To enter a Glide descent
If not an engine failure case, before entering a descent, ask yourself – have you trim your aircraft in straight-and-level?
– do it first!
Two more thing – what’s the minimum safe altitude (MSA)? AAI set?
“CFM” check – carburetor heat on, Fuel pump on, Mixture setting check
Look out – clear left, center and below and right
(do this by temporarily banking wing to left and right then back to level in a smooth way to gain more vision)
Then, use the mnemonic – P-A-T
Power – set idle power – if not FADEC or fix-pitch propeller – my own experience in a variable pitch propeller, reduce power should reduce throttle by throttle control first – i.e reduce power : throttle control to lower power →(before) propeller control to lower r.p.m. One more thing is that my own experience in propeller type aircraft, reduce throttle, left rudder.
Attitude – set the correct attitude by ASI reading – glide speed. At this moment, coarse trim to trim off the pressure first
Trim – select-hold- (fine) trim
To maintaining the Glide descent
Performance – ASI, (AAI,) altimeter/VSI, (DI, TC)
Power + Attitude = Performance
Check the engine temperatures and pressures; during a long glide descent the engine can become cool very quickly. Warm the engine every 1000 feet by increasing RPM (to cruise power) for 3 seconds
To level off from a Glide Descent
use the mnemonic – P-A-T
Power – set the correct power – if not FADEC or fix-pitch propeller – my own experience in a variable pitch propeller, increase power should increase r.p.m by propeller control first – i.e increase power : propeller control to highest rpm →(before) throttle control to full throttle. One more thing is that my own experience in propeller type aircraft, full throttle, right rudder.
Attitude – set the climb attitude
Trim – select-hold-trim
Note: As the aeroplane starts to accelerate after selecting the cruise attitude, trim off some of the pressure to more easily maintain the attitude. Fine trim once the aeroplane is steady
