Raytheon earns STC for Hawker 700 RVSM avionics
Raytheon Aircraft Services in Atlanta received an STC to upgrade existing Hawker 700A and 700B height-keeping equipment to digital altimeters with data-acquisition units to meet RVSM requirements. The installed cost averages $112,000. Downtime is about three weeks (less if the aircraft already has an air-data computer). Another RVSM option for Hawker 700As and 700Bs is Midcoast Aviation. Its RVSM packages range from $149,900 to $250,000, depending upon the extent of modifications required.
