COMMERCIAL AND BUSINESS
AVIATION ADVISORY CIRCULAR
Aeroplane Upset Training
This Commercial and Business Aviation Advisory Circular (CBAAC) is intended to bring to the attention of Subpart 705 operators a proposed amendment to the Canadian Aviation Regulations (CAR) to introduce mandatory training in recovery from aeroplane upsets.
- Airplane Upset Recovery Training Aid (Boeing/Airbus)
- Aerodynamic Principles of Large Airplane Upsets (Boeing/Airbus)
Loss of aircraft control in flight is a leading cause of injuries and fatalities in the commercial aviation industry. There have been a number of accidents and incidents in recent years, where initially in the sequence of events, the flight crew was required to deal with an unfamiliar aeroplane attitude (upset). Pilots in line operations seldom experience the excessive pitch or bank angles associated with such an aeroplane upset. A variety of reasons exist for these upsets including environmental, equipment and crew factors, with the predominant number caused by various environmental factors which cannot always be avoided or controlled. Therefore, pilots must have the necessary knowledge and skills to recover from an aeroplane upset. In 1999, the Tri-national Technical Safety Committee, in response to the Tri-national Control Flight Into Terrain (CFIT) Working Group Report, agreed to require air operators to include upset recovery training in pilot training programs.
The Airplane Upset Training Aid (Reference A) provides all the information necessary to develop and deliver appropriate training. It contains descriptions of the causes of upsets and the aerodynamics involved, recovery techniques, a sample training program and simulator training exercises. Aerodynamic Principles of Large-Airplane Upsets (Reference B) provides a more comprehensive description of the aerodynamic principles involved.
Both references were distributed by Airbus and Boeing to operators using their equipment. These references can be obtained by contacting Airbus at 305-876-6711 or Boeing at 206-662-7800.
An Notice of Proposed Amendment (NPA) requiring upset training for all Subpart 705 operators will be tabled at the June 2000 Commercial Air Services Operations (CASO) Technical Committee.
Although mandatory aeroplane upset training has yet to be approved, Subpart 705 operators are encouraged to begin the development and implementation of an appropriate training program based on references A and B.
Commercial & Business Aviation
Commercial & Business Aviation Advisory Circulars (CBAAC) are intended to provide information and guidance regarding operational matters. A CBAAC may describe an acceptable, but not the only, means of demonstrating compliance with existing regulations. CBAACs in and of themselves do not change, create any additional, authorize changes in, or permit deviations from regulatory requirements.
