Gliding Number; Air Pressure During Landing - Gatewing X100UAS System Manual

6.6.2

Gliding number

The X100 has a gliding number of 1/8. This means that, from an altitude of 100 m, the aircraft
will fly a distance of 800 m holding an angle of 7.125 ° before touching ground. The gliding
number is defined in ideal conditions (ISA, no wind).
N : During final the aircraft will always aim for the landing point. Once the aircraft passed
OTE
the point or the level (under or overshoot), it will continue in glide phase.

Air pressure during landing

Pressure drop
If the air pressure drops during the whole flight, the pictures will have a different size (offset).
The altimeter is set by a given reference and follows that reference. If the reference line has
changed compared to its true height, the actual height of the aircraft will be lower but this will
not be shown on the altimeter. No new results are put in.
