Mexico's Dirección General de Aeronáutica Civil (DGAC) has validated Butler Avionics’ FAA supplemental type certificate (STC) for the Garmin GTS 8000 TCAS II Change 7.1 for Learjet 35 and 36-series aircraft. The Olathe, Kansas-based aircraft special mission integrator and avionics modifier received the STC approval as a new installation or as a replacement for a previously installed system.
The STC'd system features the GTS 8000 TCAS II processor that interfaces with existing compatible or newly installed TCAS II/transponder controllers and the resolution advisory/vertical speed indicator displays. It also is compatible with the Garmin GTN 750 Xi upgrade, for which Butler also holds an STC.
“The cost-effective Garmin TCAS II Change 7.1 solution in Mexico is ideal for Learjets,” said Butler Avionics director Gary Morris. “We are receiving many inquiries about the TCAS II installation and are extremely pleased to offer Learjet operators a quality alternative.”
