In the air now from the volunteer receiver network
None of this operator's aircraft is in the air over the United States right now, as far as the network can hear. See them on the live map. Counted here: aircraft on the certificate. No callsign is on file for this operator, so flights under another code are not counted. Aircraft whose owners asked the FAA not to be displayed are left out.
Where the aircraft are in the air, on the ground, parked, or not heard lately · refreshed every half minute
None in the air, 4 not heard since the site began listening.
Positions from the volunteer receiver network: an aircraft is "parked" when it was last heard on the ground within 7 days (it may have moved under a hangar roof or flown with the transponder off); "not heard" means nothing has been received since the date shown. Aircraft whose owners asked the FAA not to be displayed are left out.
