Descent after Release
66.
Descent and recovery profiles are designed to minimize the effects of shock cooling on
the engine while maintaining operational efficiency. There are two descent profiles which are
executed immediately after glider release.
NOTE
To continuously monitor the cooling rate, enter manual mode on the
EDM-930 and STEP to the cooling rate parameter.
67.
Primary Descent Profile:
a.
reduce throttle to 21-
23” MAP;
b.
retract flaps to 0°;
c.
ensure the cowl flaps are closed;
d.
reduce propeller speed to 2300 RPM for noise abatement;
e.
increase IAS to approximately 130 MPH;
f.
initial cooling rate should be approximately 40° to 60° /minute;
g.
monitor the cooling rate and maintain at less than 60° /minute;
h.
as the cooling rate decreases to about 40° /minute,
reduce power to 18” MAP;
i.
cooling rate will increase, and then begin to decrease;
j.
when back down to approximately 40° /minute, reduce power by 2” of MAP;
k.
continue repeating this cycle until at about 13” MAP;
l.
reduce IAS to below 110 MPH and lower 10° of flap;
m.
extend up to full flap below 90 MPH; and
n.
complete a circuit and landing IAW local procedures.
