The Aeroflex Inc. Test Solutions Group in Wichita, Kan., is introducing the ALT-8000, the RF-based portable radio altimeter flight line test and measurement set, a portable simulator for testing radio altimeters installed in aircraft and unmanned aerial vehicles (UAVs). The ALT-8000 lightweight universal test set, which is for 4.3 GHz frequency modulated continuous carrier wave (FMCW) radio altimeters and pulse radio altimeters, has a 12-inch color touch screen. The ALT-8000 may be directly coupled to the radio altimeter transmitter/receiver (TX/RX) ports or may be connected via supplied TX/RX antenna couplers, which accommodate most aircraft antenna variants.
RF simulation of radio altitude from -100 feet to +50,000 feet (+/- 1.5 foot accuracy) is provided and altitude rate may be set to provide a smooth ramping altitude simulation to verify decision heights and altitude trips, for auto-land systems and altitude data feed to enhanced ground proximity warning systems (EGPWS). As many as three ALT-8000 test sets may be linked via an altitude sync line for executing 2- or 3-channel coordinated altitude simulation for dual or triple installation auto-land system testing.
