For cruise settings see performance section
03 DESCENT
Cruising altitude should be maintained as long as practical, however a number of
factors affecting the top of descent point are:
– Altitude
– Conditions during descent (wind, turbulence, aircraft weight).
– Weather at destination and alternate.
– Terminal area procedure.
– Runway in use.
To avoid harmful vibrations and counter weight distress, power settings should
adhere to the rule that for every 1”of MAP there should not be more than 100 RPM. If
the MAP is 20”, the RPM should not exceed 2000.
For normal descent planning preference must be given to the clean configuration.
When speed reduction is mandatory, the use of gear should be considered as
reserve feature giving a greater operating flexibility.
At top of decent point gradually lower pitch, reduce power to +/- 20” MAP
and maintain cruise speed.
