FLIGHT MANUAL
Cruising on own power
As clearly shown by the figures of section “Flight Performance”, the longest range
results from the
“sawtooth
method”,
which consists of the following flight sections being repeated as required:
„
a climb at a speed of about
95 km/h (51 kt, 59mph)
„
a glide in “clean” sailplane configuration
Thereby the height to be consumed in glide should not be less than 500 m
(1640
ft).
The maximum range in glide is achieved at a speed of approx. 110 to 120 km/h
(59-65 kt. 68-75 mph), resulting in an average speed of about 100 km/h (54 kt, 62
mph).
Should the “sawtooth method” be impracticable due to low clouds ceiling or
because of airspace restrictions, the cruising in level flight at a speed of approx.
150 km/h (81 kt, 93 mph) is also possible. The range, however, is then
considerable less – see section 5.3.2.
For cruising flight, the “sawtooth method” should always be preferred as – besides
the longer range – the crew is also less exposed to engine noise.
