During descent use the auto-pilot (VS mode) to control the rate of descent, and the throttle to control airspeed. In order to effect the initial speed reduction, the place the throttle in idle. As you deploy the larger flaps levels (15+) the aircraft can slow down quite quickly, and you will have to actively manage the throttle to avoid a dramatic loss of airspeed. Particularly for the full flaps extension it is very difficult to maintain sufficient airspeed to prevent fast descent so deploy these only when you are quite near the runway. | |||

=== When and how fast to descend? === | |||
The following rules-of-thumb apply will give you a glide slope angle of 3 deg and are easily worked out using basic trigonometry. | |||
* Altitude above airport ground (ft) should be about 318 times distance left to fly to runway head (nm) | |||
Examples: | |||
# You are flying at 20000 ft, and the airport is at 1000 ft. Your descent should start at about (20000-1000)/318 ~ 60 nm left to fly | |||
# You are 10 nm from the airport. Your altitude should be airport altitude plus 318*10 ~ 3200 ft | |||
* Assuming you are at about the correct altitude your vertical descent speed (ft/min) should be 5.3 times your speed relative ground (kts, from GPS, NOT airspeed) | |||
Example: | |||
# You are flying at 200 kts rel. ground. Your vertical descent speed should be 200*5.3=1060 ft /min | |||
