Abstract : TALAR IV operates at 15.5 GHz (Ku-band magnetron output), providing localizer and glide slope signals for approach guidance for aircraft equipped with a receiver. The FAA units were modified to provide glide slope angles between 6 degrees and 9 degrees, to include a transmitter monitor, and to transmit an identification code. The magnetron life is about 500 hours. The monitor is inadequate because of drift, but overall the TALAR has been a reliable and useful tool. The guidance signals are generally of good quality. The transmitter location, in relation to the runway, affects the pilot's ability to set the aircraft down at the desired touchdown point. (Author)
