Blended Winglets Blended Winglets For Improved Performance Besides giving the airplanes a distinctive appearance, the winglets create more efficient flight characteristics in cruise and during takeoff and climbout, which translate into additional range with the same fuel and payload. Center Of Gravity Limitations Chilling Result Of Cold Temperatures On Baro Altimeters This FSF document explains the chilling result of cold temperatures on barometric altimeters. Contaminated and slippery runways Cost Index Savings De Icing and Anti Icing fluids. A must to know. Derated Climb Performance But is it always that straightforward. Is everything actually wihed prior to the flight. How is the airplane empty weight determined. This Boeing document is a very well done brochure. Effect Of Zero Fuel Weight On Aircraft Operations. Enhanced Reduced Thrust At Takeoff Erroneous Takeoff Speeds These incidents were caused by a variety of human errors that typically resulted from using an erroneously low value for gross weight or an incorrect flap reference setting when determining takeoff speeds. This document is published by Boeing and it is well illustrated. Exceeding Tire Speed During Takeoff It is common for a jet airplane tire to carry loads as heavy as 60,000 pounds while operating at ground speeds up to 235 miles per hour. To accommodate these operational conditions, each tire has specific load and speed ratings. Tires are carefully designed and tested to withstand operation up to, but not necessarily beyond, these ratings. Flex and Derate Takeoff and Climb. For a Better Understanding of Aircraft Braking Coefficient Fuel Conservation Fuel Management Getting Hands On Experience With Aerodynamic Deteriorations All ways and means to achieve this goal have to be rationally envisaged, safety being of course the prime factor in any airline operation.

Getting To Grips With Weight and Balance Jet Fuel Characteristics Low Fuel temperatures However, when market conditions dictate, operators may use some of these airplanes on shorter flights. In such instances, appropriate action by the flight crew can reduce the likelihood of brake overheating and concomitant departure delays. Maximum Altitude Operations The most limiting of these three altitudes defines the maximum operating altitude. Operations In Mountainous Areas Performance Margins Although it is not permitted to take advantage of these margins in order to increase the aircraft performance limit weight, it is of interest to be aware of the magnitude of these margins. Pilot braking Action Reports The limitations of pilot braking action reports should be understood. Principles Of Takeoff Optimization Range of V1 Recommendations For De Icing and Anti Icing This is an exhaustive brochure. Reducing Flight Operation Cost Review Of Performance Requirements Today, operating experience and data provide the most accurate means to further improve the performance requirements of modern transport airplanes. Takeoff Speed Determination at Low Weight Takeoff Thrust Setting Understanding Improved Climb How is Improved Climb used.Understanding Takeoff Thrust Setting Technique Understanding The Angle Of Attack (Part1) Virtually any book on these subjects, as well as basic texts and instructional material written for flight crews, defines AOA and discusses its many attributes. Understanding The Angle Of Attack (Part2) Recent accidents and incidents have resulted in new flight crew training programs, which in turn have raised interest in AOA in commercial aviation. Awareness of AOA is vitally important as the airplane nears stall. It is less useful to the flight crew in the normal operational range. On most Boeing models currently in production, AOA information is presented in several ways: stick shaker, airspeed tape, and pitch limit indicator.

A wide variety of different aspects have to be taken into consideration in this process, such as airline economics, airline management, flight operations, maintenance management, technical condition of aircraft. The purpose of this document is to examine the influence of the latter with respect to aerodynamic deterioration. Getting to Grips to Aircraft Noise Indeed, unlike a Mozart?s symphony, airplane noise is one of those sounds which are undesirable to most of the observers. Its various effects on man, especially on the people living in the vicinity of civilian and military airfields must be studied to be better accounted for. This shall allow the determination and continuous refinement of indices reflecting noise impact, in order to develop an appropriate noise policy. The latter has the difficult mission to conciliate both the noise reduction around airfields while not penalizing too much the airlines operations, that is to say the air transport industry as a whole. Getting to Grips With Aircraft Performance Great information. Getting To Grips With ALAR Getting To Grips With Cold Weather Operations Getting To Grips With Fuel Economy Getting To Grips With Perfomance Monitoring This brochure was designed to provide guidelines for aircraft performance monitoring based on the feedback obtained from many operators and on the knowledge of Airbus aircraft and systems. Getting To Grips With The Cost Index All ways and means to achieve this goal have to be rationally envisaged, safety being of course the prime factor in any airline operation. A wide spectrum of considerations intervene in this process stemming from airline economics, marketing management, crew scheduling, flight operations, engineering and maintenance management, technical condition of aircraft. The idea behind this document is to revisit the cost index concept with a view towards balancing both fuel- and time-related costs.

Understanding Airplane Turbofan Engine Operation Helps Flight Crews Respond to Malfunctions This document covers all phases of flight from the preliminary cockpit preparation to the end of of the flight. Airbus Go-Around Essentials Aircraft Energy Management During Approach This Airbus Flight Operations Briefing Note provides background information and operational guidelines for a better understanding of energy management during intermediate approach and during final approach. Airplane Upset Recovery by Airbus Airplane Upset Recovery by Boeing (Part 2) Flight crews should be aware of the compounding nature of these hazards during approach and landing. Attitude Adjustment Operations on contaminated runways are not considered during certification but the case is practically studied. This article has been published for the 10th Performance and Operations Conference in 1998. Avoiding Altitude Deviations Safety can be jeopardized when aircraft deviate from their assigned altitudes. Carefully implemented altitude awareness programs have been adopted by some airlines. These proven programs focus on improving communications, altitude alerter setting procedure, crew prioritization and task allocation, and ensuring correct altimeter settings. Avoiding Tailstrikes by Airbus Avoiding Tailstrikes by Boeing Very interesting document. Baghdad A300 Incident After having lost hydraulic power, the crew had then to learn how to fly and land an asymmetric aircraft using the only thrust control. Airbus explains this whole incredible and dramatic story. Bound Recovery and Rejected Landing Techniques Brake Energy Consideration In Flight Operation Crosswind Guidelines Crosswind Landings Technique Descent and Approach Profile Management. Either situation increases the risk of approach-and-landing accidents, including those involving CFIT.

Boeing has also developed a dedicated AOA indicator integral to the flight crewa??s primary flight displays. V1 and GO No Go Decision Wet Runway (Physics Certfication and Application) Ask around you and you should be surprised of some answers. This Boeing document explains the hidden side of the wet runway concept. Wingtip Devices When operating at reduced TOGW, reduced thrust (derate) may be used in both takeoff and climb to extend engine life and reduce maintenance cost. EGT Margin by CFM Engine Operation and Malfunctions This document will also provide pertinent information about malfunctions that may be encountered during the operation of turbofanpowered airplanes, especially those malfunctions that cannot be simulated well and may thus cause confusion. Engine Performance Deterioration by CFM These events typically have occurred in conditions that appear benign to pilots, including an absence of airframe icing and only light turbulence. Engine Regulation by CFM Although ita??s a difficult problem to isolate, airlines can take steps to deal with it, including auditing fuel suppliers to ensure that they are following applicable fuel handling requirements and replacing engine fuel filters more often. Handling Engine Malfunctions Ice Crystal Weather Threat To Engines Some types of vibration can be expected from time to time and are considered normal. However, isolated cases of abnormal vibration require prompt flight crew response and subsequent timely maintenance action. Jet Engines Basics A very well illustratated document. Preventing Engine Ingestion Injuries The risk of ingestion can be prevented with appropriate training and adherence to the safety precautions The Migration To Higher Thrust Engines And The Effect On Control Speeds This original engine was rated at 74000 pounds of thrust and was envisioned to grow to around 95000 pounds of thrust.

Performing Safe Go-Around Maneuvers Once a go-around decision has been made, flight crews must focus on ensuring that the maneuver is flown correctly by being aware of the difficulties that can occur and following the appropriate procedures to address those difficulties. A go-around maneuver can be both effective and safe when performed according to standard operating procedures by crews who are alerted to possible hazards. Preparing The Approach In Case Of Engine Failure It also reviews the case of multiple failures, use of the autopilot and autothrottle. This document contents an exhaustive study on a topic rarely detailed. Preventing Altitude Deviations and Level Busts This document can be used for stand-alone reading or as the basis for the development of an airlinea??s altitude awareness program. Preventing Hard Nosegear Touchdowns In most cases, the main gear touchdowns were relatively normal. The damage resulted from high nose-down pitch rates generated by full or nearly full forward control column application before nosegear touchdown. Flight crews need to be aware of the potential for significant structural damage from hard nosegear contact and know which actions to take to prevent such incidents. Preventing Tail Strikes In the most extreme scenario, a tail strike can cause pressure bulkhead failure, which can ultimately lead to structural failure; however, long shallow scratches that are not repaired correctly can also result in increased risks. Yet tail strikes can be prevented when flight crews understand their causes and follow certain standard procedures. Preventing Tailstrike at Takeoff Preventing Tailstrikes At Landing Proper Landing Technique It discussses the key elements that lead to a good landing. Pushback Hazards From 1964 through December 1991, a search of the Boeing Product Safety Jet Transport Safety Events data base revealed 31 reported accidents worldwide where personnel were run over by the airplane wheels during the pushback process.

Quiet Climb By reducing and restoring thrust automatically, the system lessens crew workload and results in a consistently quiet footprint, which helps airlines comply with restrictions and may allow for an increase in takeoff payload. Reducing Runway Landing Overruns Reducing the Risk of Runway Excursions This was an international effort with participants representing the full spectrum of stakeholders from the aviation community. The effort initially reviewed the three areas of runway safety: runway incursions, runway confusion, and runway excursions. After a review of current runway safety efforts, specific data on the various aspects of runway safety were obtained. After reviewing the initial data, the RSI Group determined that it would be most effective to focus its efforts on reducing the risk of runway excursions. Rejected Landing Although a rare occurrence, a rejected landing is a challenging maneuver decided and conducted in an unanticipated and unprepared manner. Rejected Takeoff On Slippery Runway Response To Stall Warning Activation at Takeoff. However, the key points at the end of this briefing note are also applicable to all aircraft types, with or without flight envelope protection. Slippery Runways Stabilized Approach And Flare Against Hard Landings The accident record shows that hard landings often involve substantial damage and sometimes result in fatalities. Stall Review and Recovery Procedures The decision on whether or not to perform a rejected takeoff -specifically, on whether or not to STOP or GO- requires comprehensive flight crew awareness of the many risks involved. The aim of this Airbus Flight Operations Briefing Note is, therefore, to review the STOP or GO decision-making process, and the associated operational and prevention strategies to be applied, in order to limit the risks of taking inappropriate actions and unsafe decisions. Tailstrikes In Gusty Wind Tailwind Operations Takeoff and Landing In Icing Conditions.

Driftdown and Oxygen Procedures Over High Terrain Flying Stabilized Approaches Fuel Conservation Strategies - Cost Index Explained However, many operators don?t take full advantage of this powerful tool. Fuel Conservation Strategies: Cruise Flight As an additional benefit, the less fuel consumed, the more environmentally friendly the flight. Fuel Conservation Strategies: Descent and Approach Fuel Conservation Strategies: Takeoff and Climb If each takeoff and climb is performed efficiently, an airline can realize significant savings over time. But what constitutes an efficient takeoff. How should a climb be executed for maximum fuel savings. The most efficient flights actually begin long before the airplane is cleared for takeoff. Getting To Grips With CATII and CATIII Glasscockpit Transition Go-Around - Failure to Mitigate The timing of the decision can be critical to the maneuver?s outcome. Go-Around Study They noted that the almost complete (97 percent) failure to call go-arounds as a preventive mitigation of the risk of continuing to fly unstable approaches constituted the no. 1 cause of runway excursions, and therefore of approach and landing accidents. Hazards Of Flight In Heavy Rain The first casualty was a Korean Airlines Boeing 747 which came down on Guam, and the second, a Vietnamese Tupolev in Cambodia. Both aircraft accidents occurred in torrential rain on approach to an airport. Although it may turn out that rain was not a factor in either of these accidents, research indicates that heavy rainfall can have a significant effect on the performance of an aircraft. High Altitude Handling An understanding of handling characteristics at various CG positions and altitudes permits flight crews to use proper control inputs when manually flying throughout the flight envelope. How to Make Go-Arounds Safer One in ten go around reports records a potentially hazardous go-around outcome. This article gives some hints on how to make it more efficient and safer.

Insidious Ice Landing on Contaminated Runways Aircraft Landing Performance data takes account of the deceleration issues in scheduling the Landing Distance Required (LDR), and the Aircraft Limitations specified in the AFM can be expected to impose a reduced maximum crosswind limitation. Operator Procedures may further restrict all such operations, or impose flight crew-specific restrictions or requirements. Despite all procedural precautions, contaminated runway landings are a rare event for most flight crews and although this serves to ensure a full focus on the task, the lack of real experience, and the limited ability to create realistic scenarios in most simulators, means that a full understanding of the issues involved can be an additional safeguard. Landing On Slippery Runways This document reviews available landing data, certified data, QRH adisory data and many other topics. Landing Overruns Let's Be Careful During Visual Approaches The training is conducted in an aerobatic single-engine airplane and in a multi-engine jet modified as a variable-stability in-flight simulator. Moment of Truth Operations On Grooved Runways Optimum Use Of Automation. Overweight Landing What to Consider A pilot may consider making an overweight landing when a situation arises that requires the airplane to return to the takeoff airport or divert to another airport soon after takeoff. In these cases, the airplane may arrive at the landing airport at a weight considerably above the maximum design landing weight. The pilot must then decide whether to reduce the weight prior to landing or land overweight. The weight can be reduced either by holding to burn off fuel or by jettisoning fuel. There are important issues to consider when a decision must be made to land overweight, burn off fuel, or jettison fuel (when possible).

Takeoff Rotation This document is specific to Airbus pilots. Takeoff Safety Training Aid Takeoff With Upper Wing Frost Taxi Procedures This Airbus document reviews some safety precautions specific to Airbus aircraft, pushback and taxi techniques (One-Engine Taxi - A340 Two Engines), powerpush, taxi with Deflated Tires, etc. Taxing with Carbon brakes. Analysis has revealed a difference between the wear characteristics of carbon versus steel brakes. It is believed that improvements in carbon brake life can be achieved through better understanding of the operational factors affecting carbon brake life. Teaching UPRT For most of their instructors, too, these places until recently were unfamiliar territory. This article explains why that is the case, and will help newcomers to this subject quickly grasp the essentials of the paradigm shift under way. Understanding Runways Excursions The excursion may be intentional or unintentional.Understanding The Stall Recovery Procedure For Turboprop in Icing Conditions Unreliable Speed Use Of Rudder On Airbus Aircraft. The purpose of this Airbus FCOM Bulletin is to re-emphazise proper operational use of the rudder, highlight certification requirements and rudder control design characteristics. Use Of VNAV On NPA One of the most profound capabilities being exploited recently is the aircraft?s capability of navigating vertically on an instrument approach without reference to an external electronic guidance signal such as an ILS glideslope or MLS elevation signal. Vertical command information may be retrieved from the aircraft?s aeronautical information database or from the pilot?s input into the Flight Management System (FMS). Vertical command information while conducting VNAV on a conventional non-precision approach is normally retrieved entirely from the aircraft?s aeronautical database.

V1 Other revisions change the method of compensating for the time required by pilots to take action to reject a takeoff; require accelerate-stop data based on airplanes with fully worn brakes; and require wet-runway takeoff-performance data in airplane flight manuals. Visual Approaches An interesting review initiated by Captain Fred H. LORENZ has been published sometime ago. Visual Illusions Wake Turbulence Awareness and Avoidance What Lies Below Why and When To Perform a Go Around Maneuver Most runway excursions can be attributed at least in part to unstabilized approaches, and runway excursions in several forms are the leading cause of accidents and incidents within the industry. Airlines should emphasize to flight crews the importance of making the proper go-around decision if their landing approach exhibits any element of an unstabilized approach. Training recommendations and strategy. Accumulated Stress Air It Out Analysis of Crew Conversations Provides Insights for Accident Investigation Antidepressants in Aviation Approach and landing Risk Reduction Guide This guide should be used to evaluate specific flight operations and to improve crew awareness of associated risks. This guide is intended for use as a strategic tool (i.e., for long-term planning). Calculating Errors Challenging Behavior Cognitive Engineering Analysis Of VNAV These two types of overloading, resulting in modal input devices and ambiguous feedback, are well known sources of operator confusion, and explain, in part, the operational issues experienced by airline pilots using VNAV in descent and approach. A proposal to modify the existing VNAV design to eliminate the overloading is discussed. Communicate Positively with your Passengers Conducting Effective Briefings Effective briefings should be short, structured, concise and adapted to the particular conditions of the takeoff or approach-and-landing.

The information provided in this document has been expanded on purpose to provide an opportunity to review and discuss in details each briefing item. Coping With Long range Flying During long-haul rotations, partial or complete compliance with these recommendations should allow pilots to better manage their levels of alertness in flight, limit sleep loss related to night flights, facilitate, if applicable, adaptation to local layover times, depending on time zone differences. The choice of recommendations will of course have to be adapted to the circumstances. Partial reliance on these recommendations is therefore also acceptable. Crew Alertness On Ultra Long Range Operations Specialists at these meetings forged operational guidelines that will help the airline industry to expand the operational envelope while maintaining safety. CRM Aspects In Accidents and Incidents In incident and accident reports, the flight crew's contribution often is considered to be just what the flight crew did or did not do. This briefing is a focused but limited overview of the broad CRM subject. Decision Making The decision-making process produces a choice of action or an opinion that determines the decision maker's behavior and therefore has a profound influence on task performance. Decision making in an aeronautical environment involves any pertinent decision a pilot must make during the conduct of a flight. In aeronautics, decision making is of particular importance because of the safety consequences of poor decisions. Decision Trees and Bowties Discipline as Antidote Discipline in Aviation Its objective is to reinforce the importance of discipline as the foundation of airmanship and the need to follow procedures to ensure safe operations. The article also demonstrates that poor discipline is the direct result of attitudes that may lead a pilot to deviate from Standard Operating Procedures (SOPs).

It also describes defenses and controls for these attitudes that will enable flight crews to enhance flight safety through improved personal discipline. Dry and High Effective Pilot and Controller Communications Enhancing Flight crew Monitoring Skills Can Increase Flight Safety Monitoring can be degraded because of several factors, including preoccupation with other duties. Enhancing Situation Awareness It explains the complex process of gaining and maintaining situational awareness, focuses on how it may be lost and proposes prevention and recovery strategies. This briefing note is intended to help the reader gain and maintain situational awareness, to prevent falling into the traps associated with the loss of situational awareness and to avoid the adverse effects of the loss of situational awareness on flight safety. Error Management Explaining Leadership and Followership It is a continuation of the project to identify leadership and followership skills used in CRM, and builds on the previous published manual Cockpit Leadership and Followership Skills: Theoretical Perspectives and Training Guidelines. Flight Crew Briefing Handling an emergency For those who do pull the short straw however, there are some basic considerations that apply, regardless of the specific problem(s). The desired outcome for any emergency situation is a controlled rate of descent onto a prepared surface. How To Deal With A Fire in flight. Human Factors Aspects In Incidents and Accidents This summary may be used either to assess: the company exposure and develop corresponding prevention strategies,or the readera??s individual exposure and develop corresponding personal lines-of-defense. Ultimately, human factors are involved in all incidents and accidents. Whether crew-related, ATC-related, maintenance-related, organization-related or design-related, each link of the safety chain involves human beings and, therefore, human decisions and potential human errors.

Human Factors Considerations for Performance Based Navigation Pilots must allow adequate time to properly load and brief their SID, STAR, and approach charts. While containing many elements common with existing procedures, these procedures can be more detailed than their conventional counterparts. Considering the increased reliance on the FMS for RNAV and RNP procedures, airlines may benefit from reviewing their training programs and ensuring that they meet pilot workload and situation awareness demands. Human Factors In Accidents and Incidents It may be used either to assess the company exposure and develop corresponding prevention strategies, or, the readera??s individual exposure and develop corresponding personal lines-of-defense. Human Factors Report Propulsion System Malfunction Plus Inappropriate Crew Response The NTSB findings in this event strongly suggested that a warning light intended to indicate the activation of a recovery function was falsely interpreted as an engine failure and led to inappropriate crew action. The FAA recognized that there were additional data suggesting that this accident was one of a number of similar accidents, and that a study would be appropriate to look into all commercial transport accident histories where an inappropriate crew action may have been taken in response to what should have been a benign propulsion system malfunction. Hurry Up Syndrom. The Air Line Pilots Association (ALPA) conducted an eighteen month, three country investigation of this accident, with an emphasis on the human factors of flight crew performance, ALPA found that the KLM crew had strong concerns relating to duty time, specifically that they would be able to return to Amsterdam that evening and remain within their duty time regulations. They also expressed concern about the weather and its potential to delay the impending take-off. Identifying Possible Risk Of Hearing Loss Increasing Efficiency of Communication.
