Air pressure during cruise flight
Pressure drop
If the air pressure drops during cruise 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.
C
: Mind the 25 m vertical separation when there is a high risk of air pressure drops.
AUTION
Pressure rise
If the air pressure suddenly rises during cruise flight, the X100 will climb in height.
Sudden air pressure drops
The air pressure can drop suddenly:
●
When there are big differences in temperature on a very short distance
●
After a local thunderstorm
●
When a cold or warm front is passing through
