It only takes a minute to sign up. 0, 180 indication should a pilot receive when a VOR station is undergoing maintenance and may be considered unreliable? -The CDI must then center within _ degrees of the radial. A course deviation indicator (CDI)[1] is an avionics instrument used in aircraft navigation to determine an aircraft's lateral position in relation to a course to or from a radio navigation beacon. terminology - What is Full scale deflection? - Electrical Engineering Radio beams are not perfectly accurate, nor are receivers. tailored course width provides for 700 feet between the full-scale The airborne DME may appear normal, but there will be no code tone. On the standard CDI, full scale deflection is indeed 2.5 degrees in ILS mode. What were the most popular text editors for MS-DOS in the 1980s? (Refer to Figure 64) The course deviation indicators (CDI) are centered.
