Performance
TAKE-OFF
Take-Off Distance is shown by Fig. 5.5
Example:
-T/O Weight: 870 kg (1918 lbs)
-Ground Roll: 112 m (367 ft)
-Total Distance to clear a 50 ft obstacle: 248 m (813 ft)
These distances are well within the available field length incl. the 8 Kt headwind.
RATE OF CLIMB
Fig. 5.6 shows the Rate Of Climb using Takeoff Power
The Rate of Climb at 2000 ft : 2320 ft/min
The Time to Climb from 2000 ft to 8000 ft is acc. to Fig. 5.7:
=> (4,0 - 0,9) min = 3,1 min
The Fuel to Climb from 2000 ft to 8000 ft is:
=> (5,8 - 1,4) Liters = 4,4 Liters (1.2 US Gal.)
CRUISE
Cruise Altitude and Power Setting should be determined for most economical fuel
consumption and several other considerations. In an altitude of 8000 ft and a Power Setting
of 65 % a Fuel Consumption of 52 L/H (13.7 US Gal/H) and 3,25 NM/L (12.3 NM/US Gal)
can be obtained by Fig. 5.9.
RANGE AND ENDURANCE
Fig. 5.8 presents Range and Endurance values for a T/O Weight of 920 kg (2028 lbs)
including fuel for warm up and Take-Off from SL, max continuous Power climb to cruising
altitude, and a reserve of 21 liter (5.5 US Gal.) for 45 minutes with 45% Power. 2 liters (0.53
US Gal.) unusable fuel is taken into account.
For the sample problem (appr.)
Total Fuel 171 L (45.17 US Gal.)
Warm Up & T/O- 5 L (1.32 US Gal.)
Reserve - 21 L (5.55 US Gal.)
Unusable Fuel - 2 L (0.53 US Gal.)
====== ============
Usable Fuel 143 L (37.8 US Gal.)
Range 415 NM (768 km)
Endurance 2.49 HRS
