SIMULATING FLIGHT CONDITION OF HFSSB ON GROUND
2015
HF (high frequency) system is used for long distance communication in aircrafts from air to ground or ground to ground.Since it is not line of sight communication it is difficult to get reception in closed areas like hangars.If the communication system is found unserviceable during flights it is difficult to determine whether the problem lies in the LRU (line replaceable unit) or the loom (wiring).If the wiring is found proper it is still difficult to recognize and replace faulty LRU.To overcome these problems and to check the functionality we simulate flight condition on ground using test kit.
