1.	Which of the following is one of the countermeasures for IR detection?(a) Decoy(b) Temperature increase(c) Engine exhaust temperature increase(d) Not mixing plume with outside airThe question was posed to me in an interview for internship.I need to ask this question from Configuration Layout Considerations in portion Configuration Layout Considerations of Aircraft Design
Answer» Right ANSWER is (a) Decoy The EXPLANATION is: A decoy is an off-board system. Decoy is a COUNTERMEASURE that is ejected from and separated away from the aircraft. Decoy will TRY to LURE the missile track away from the aircraft.
