Chapter 13 Abnormal and Emergency Procedures Introduction This chapter contains information on dealing with abnormal and emergency situations that may occur in flight. Aeronautical decision-making (ADM), a systematic approach to determine the best course of action in response to a given set of circumstances, should always be used rather than making a quick decision without determining the best outcome. Most emergencies can be prevented by making the proper decisions. This may be the fi rst go/no-go decision of whether to fl y, when to fl y, or where to fl y. All safe fl ights start with proper prefl ight planning.Throughout this chapter, all abnormal and emergency decisions should be based on ADM. Some situations allow more time than others to evaluate the outcome. ADM should be applied to any unplanned or unexpected situation presented. In addition to ADM, the key to any emergency situation, and/or preventing a abnormal situation from progressing to a true emergency is a thorough familiarity with, and adherence to, the procedures developed by the manufacturer and contained in the Aircraft Flight Manual and/or Pilot’s Operating Handbook (AFM/POH). The following guidelines are generic and not meant to replace the manufacturer’s recommended procedures. Rather, they are meant to enhance the pilot’s general knowledge in the area of abnormal and emergency operations. If any of the guidance in this chapter confl icts with the manufacturer’s recommended procedures for a particular make and model weight-shift control (WSC) aircraft, the manufacturer’s recommended procedures take precedence. Ballistic Parachute System (BPS) The ballistic parachute system (BPS) provides an additional safety margin to fl ying WSC aircraft. However, if utilized when other alternatives would produce a better outcome or if not deployed with the proper procedures, BPS system use could create a worse situation than not using a BPS. The BPS should be used only as a last alternative and only after other options have been evaluated through ADM. [Figure 13-1] The choice of adding a BPS as an additional system for emergencies is up to the pilot. This decision should be made by evaluating the disadvantages of an additional system, its advantages, and the situations in which the system would be utilized. Advantages of a BPS: • BPS can be used if there is a total loss of control of the WSC. The term “loss of control” is key to when the BPS should be deployed. Always fl y the aircraft fi rst, but if the pilot cannot control or regain control of the aircraft (loss of control), this is when the BPS should be used. Loss of control might result from midair collisions or wake tip vortices with other aircraft. A loss of control could also result from structural failure due to inadequate prefl ight or lack of proper maintenance. • BPS can be used if the engine quits and there are no suitable landing areas. Although pilots try to have a suitable landing area within gliding distance, there are times when a parachute could be used with an engine failure, such as over high trees. • Pilot incapacitation is a situation where the BPS could be used. This could be a pilot-in-command (PIC) illness, such as a heart attack, or an external factor, such as a bird strike in the face temporally blinding the pilot. For example, if the pilot is incapacitated by a bird strike, the pilot could feel for the handle and pull it. Other designs allow the pilot and passenger to be able to reach and actuate the BPS, while other designs have two separate handles for the pilot and a passenger. Many passengers feel safer if they know they can actuate the BPS if the pilot is unable to fl y the aircraft. • Pilot disorientation with loss of control of the aircraft is a situation where the BPS could be used. In the unusual situation of severe vertigo or spatial disorientation preventing the pilot from differentiating up from down, such as severe turbulence, night fl ying, or fl ying into bad weather, a BPS could be used. Attempts should always be made to regain composure; if attempts fail, then the BPS is an option. Disadvantages of having BPS: • It provides a false sense of security. A pilot might believe that the BPS can save him or her from hazardous situations, which could cause the pilot to develop hazardous attitudes, exceed limitations, and make bad decisions.
