Generally, the maximum attack height of MANPAD is not more than 10000 feet, so it is the safest to maintain a sufficient height. If it is necessary to lower the height, remember to complete and disengage quickly, and when the height is reduced, throw the flares at a certain interval.
In addition, if you confirm that you have been attacked by MANPADs, you must reduce the throttle valve, and then throw a larger number of flares, which can greatly increase the probability of cheating missiles.
Never increase the throttle valve (afterburning), which will make your infrared signal more obvious and easier to be hit.
