6.2 Flight performance
Climb performance and range
6.2.1
Table 6.2-1 gives the optimum IAS to climb for best range at empty
weight with the following assumptions:
Usable fuel quantity (21.87 liters / 5.78 US gal)
Empty mass 400 kg ((882 lbs) excl. fuel).
Flight profile: Saw tooth profile
NOTE:
Optimum range is obtained by flying a saw tooth profile with
climbs at maximum continuous power and glide with engine off
and retracted.
NOTE:
The range specified in Table 6.2-1 and Table 6.2-2 applies to
both the 15 m and 18 m configurations. In 18 m configuration,
fly 3% less than specified climb airspeeds.
NOTE:
The glide distance calculated in Table 6.2-1 and Table 6.2-2
assumes a glide ratio of 50:1 at best glide speed with the
engine retracted.
NOTE
: The performance values listed in this section are theoretical
predictions based on experimental studies and aircraft in clean
configuration achieving optimal drag performance with engine
extended and retracted as required. These values will vary
depending on the atmospheric conditions and configuration of
the aircraft.
