The IFR Aeroflex ALT-8015 is a portable flightline test set for comprehensive testing and troubleshooting of military pulse and FMCW/CDF radio altimeters. It replicates in-flight conditions to isolate faults across installed aircraft systems, from transceivers to cockpit indicators, and supports civil and military aviation applications.
