Hello all,
What is wrong in receiver software or hardware because many light aircraft (including my N446MM) seen in FR24 are temporary indicating 0 ft altitude.
Or is the problem somewhere else? Have a look at these examples:
There are no similar problems with airliners which are typically using enhanced surveillance S-mode transponders.
Is the problem related to elementary surveillance S-mode ADS-B transponders which are mainly used in light aircraft?
Or is this problem related only to a certain type of transponder?
Currently the following ADS-B S-Mode transponder types are typically used in light aircraft.
- Trig TT21, TT22, TT32,
- BendixKing KT74
- Avidyne AXP340
- Garmin GTX-330 with ES
My transponder is BendixKing KT74.
ATC is happy with my altitude although FR24 is indicating 0 ft.
Where is the problem?
