EXTRA 500 Performance
5.4.d Landing
Note Average fuel density is 0.814 kg/l.
Jet Fuel density will vary with its temperature.
To obtain the landing weight, the weight of required fuel
(520.7 l = 424 kg) must be subtracted from the aircraft ramp
weight!
The calculation therefore is:
In kilogram: 2130 kg minus 424 kg = 1706 kg.
In pounds: 4696 lbs minus 935 lbs = 3761 lbs.
For the above calculated landing weight and the assumed
atmospheric conditions, the landing distance chart will give the
following result:
Ground roll: 295 m (967 ft)
Total distance to clear 50 Feet obstacle: 680 m (2230 ft)
Therefore the distances are well within the runway length.
For a possible balked landing the climb speed can be found in
figure 5-12, sheet 1. For 1769 kg, 3000 ft, climb speed of
80 KIAS and ISA +10 °C, the climb rate is 1455 ft/min.
Caution If the balked landing climb gradient cannot be maintained
for a certain weight and temperature, it is prohibited to
attempt to land at that airfield.
