The often misunderstood source of system anomalies.
Throughout my flight test career, when asked to troubleshoot flight test events like a rudder kick in a turn, pressurization bump in descent, indicator lights flickering, or noise on a communication radio, the investigation resulted with a common thread through all these situations, electromagnetic interference or EMI.
There are many famous examples of electromagnetic interference, ranging from nuisances to catastrophic failures with loss of life. One of the earliest tragic accidents occurred in 1967 onboard the US aircraft carrier Forrestal, which was deployed off the coast of North Vietnam. An uncommanded missile launch from one of the aircraft parked on the flight deck, causing an explosion and fire from the erupting fuel tanks. 134 servicemen died in the accident which was thought to be caused by the ship’s high-powered radars generating a high voltage within the missiles fire control system.
Another serious example was the series of fatal accidents of the UH-60 Black Hawk helicopter started in 1982 that killed a total of 22 servicemen. Investigations discovered that the electronic flight control system was susceptible to the radio frequency energy when flying near high powered radio transmitters.
All these occurrences required extensive investigation, ground and flight testing and airplane wiring modifications to find and correct the interference.
