1.	What are the maximum number of channels in an instrument landing system?(a) 900(b) 90(c) 40(d) 400The question was asked in quiz.Question is taken from Aviation Communication Systems topic in chapter Aviation Communication Systems of Aircraft Maintenance
Answer» Right option is (c) 40 The BEST explanation: There can be a maximum of 40 CHANNELS in an INSTRUMENT Landing System. The channels are alternatively modulated at 90 Hz and 150 Hz. Signals from these channels are transmitted by MEANS of co-located antennas.
