Aircraft Geometric Height Measurement Element (AGHME)

The ground-based Aircraft Geometric Height Measurement Element (AGHME) is available in Atlantic City, NJ, to monitor all aircraft passing through its coverage volume. AGHME locations and operational status provides information about its location and associated availability dates.

The AGHME system does not require that any special monitoring devices be installed on an aircraft in order that it be monitored. It is necessary, however, that the aircraft have an operational Mode S transponder.

Any operator wishing to use the AGHME constellation to satisfy monitoring requirements should follow the instructions provided under AGHME monitoring procedures

ADS-B Out RVSM monitoring - Aircraft equipped with qualified ADS-B Out systems are height-monitored each day during normal operations in US ADS-B rule airspace at RVSM altitudes. Aircraft that are due for periodic monitoring or that must verify performance can fly any day to obtain a monitoring result. Click this link to read more on Monitoring Methods.

The complete source for all operator/aircraft RVSM information is available at RVSM documentation.
