How to enter, maintain and exit Descending Maneuver?

[Ref FTA material 2016]

To enter a Glide descent

TEM:

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

ALALP

Performance – ASI, (AAI,) altimeter/VSI, (DI, TC)

Note:
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

Look out

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
