It is very, very quiet here on a wet Saturday morning.
No GA and only two aircraft within range.
On the Flightaware web page I can see a third plane, VH-YXK, at 20,000 about 15 km from here at MEN which is not visible on any of the 6 piaware I have in Melbourne. It is also not visible on Planefinder nor Flightradar.
The aircraft is an Agusta AW139 helicopter
and the tracklog shows it climbed from the deck to 20,000 in one minute. The tracklog also shows that it is ADS-B and not MLAT.
- Service ceiling: 6,096 m (20,000 ft)
- Rate of climb: 10.9 m/s (2,140 ft/min)
Is there any explanation for this information?
