What is EMC?(a) Electromagnetic capture(b) Electromagnetic compatibility(c) Electromagnetic combat(d) Electromagnetic courseThis question was posed to me in an interview.Query is from Fly-by-Light Flight Control in division Fly by Wire Flight Control of Avionics

Answer»

Right choice is (b) Electromagnetic compatibility

For explanation: EMC or Electromagnetic compatibility is the ability of the aircraft equipment to withstand HIGH levels of EMI. This is a necessary condition as many cases have occurred of aircraft experiencing SEVERE transients in the automatic FLIGHT control SYSTEM placing the aircraft temporarily out of control whilst overflying high power radar/radio transmitters. This has been due to the susceptibility of the flight control system analogue ELECTRONICS to EMI because of inadequate electro-magnetic screening.
