Cruising on own power
As clearly shown by the figures of section "Flight Performances", 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 - 100 km/h, (51 - 54 KIAS,
59 - 62 mph)
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 about 120
km/h (64 KIAS, 74 mph), resulting in an average speed of about
110 km/h (59 KIAS, 68 mph).
Should the "sawtooth"-method be impracticable due to low cloud
ceiling or because of airspace restrictions, then cruising in level
flight at a speed of about 150 km/h, (80 KIAS, 88 mph) is also
possible. The range, however, is then considerably less – see page
5.3.3.
For cruising flight, the "sawtooth" method should always be
preferred, as besides the longer range the pilot is much less
exposed to engine noise (RPM’s in climb are less than in level
flight).
