In anaircraft with a squat switch, setting the Mode switch to ALT when the aircraft is on theground should leave the transponder in GND mode; when the aircraft becomesairborne, the mode should switch automatically to ALT.Interrogations to verify the receiver sensitivity. A Mode S transponder should have aminimum triggering level (MTL) of between -77 dBm and -71 dBm. Failure to meet thisrequirement usually indicates antenna or coaxial cable problems.Interrogations to verify the transmitted power. A Class 1 installation should have no lessthan 125 Watts at the antenna (and no more than 500 Watts).
