GMU Height Monitoring
A key component of RVSM implementation is monitoring of the height-keeping performance of aircraft that have received their RVSM Airworthiness Approval. Height monitoring can be accomplished by either trained technicians using a portable GPS-based Monitoring Unit (GMUs) or by flying over a ground-based monitoring system (AGHME). The data required for verification can be collected on either a scheduled flight or a dedicated special flight test.
AeroMech can assist with the FAA-mandated height monitoring requirement by dispatching a trained technician to perform an on-aircraft GMU test. A typical monitoring flight will take no more than two hours and consist of approximately 30 minutes of data collection at an RVSM altitude (FL290-FL410).
AeroMech is one of few companies that have recently acquired the Enhanced2 GPS-Monitoring Unit (E2GMU). This new equipment was developed using the latest GPS receiver technology, ensuring a successful flight test.
