One of the leading causes of fatal general aviation accidents is loss of control.
When the airplane attitude is that not normally required for flight, you have entered an unusual attitude. Unusual attitudes may also be referred to as a “unintended” or “unexpected” attitude.
It is important to note, that in order to recover from an unusual attitude, it is first necessary to properly detect the unusual attitude in order to issue the correct control inputs to resolve the issue. Recovering from unusual attitudes becomes more difficult in IMC, or “Instrument Flight Conditions”, as outside visual references can no longer be relied upon. Under these instances, it is possible, to lose control of the aircraft without even realizing it.
When in IMC, it is essential that you rely upon your instruments and not your senses.
When in IMC it is possible to loose control of the aircraft without realizing it
During IMC conditions you should rely on the instruments and not your senses
Neutralize controls (stick and rudder), analyze and evaluate the situation to determine recovery
Occurs when the perceived aircraft attitude and the actual aircraft attitude different
The real attitude may or may not be extreme relative to the horizon
To ensure you can recover under the worst conditions (unaided night/IMC) you will be expected to follow a mini-checklist (this is a form of an emergency)
Results from turbulence, disorientation, instrument failure, confusion, preoccupation, carelessness, errors, lack of proficiency
To maintain aircraft control when faced with these or other contributing factors, the pilot must be aware of situations where LOC-I can occur, recognize when an airplane is approaching a stall, has stalled, or is in an upset condition, and understand and execute the correct procedures to recover the aircraft
Yes, what you are about to embark upon will be quite unusual. Your CFI is about to make you close your eyes while wearing a view-limiting device, and put the airplane into either a steep nose up or steep nose down attitude, and ask you to open your eyes and rapidly recover. While this may seem a little crazy, it is actually quite a bit of fun, and incredibly important to master this skill to have a better chance of recovering from such a situation should you accidentally put yourself into such a scenario when you are out flying.
Unusual Attitude Recovery Procedure:
Nose High:
Level the wings using coordinated aileron and rudder
Add full power
Lower the nose to just slightly above the horizon to ensure the aircraft will accelerate (airspeed) and climb away from the ground
Re-trim as necessary
Nose Low:
Level the wings using coordinated aileron and rudder
Reduce power to idle
Raise the nose to just above the horizon to ensure the aircraft will accelerate as well as climb away from the ground
Add full power and establish a climb
Re-trim as necessary
