Electrical supply of aircraft during parking

The elaboration discusses selected aspects of parking supply of aircraft with electricity generated by mobile, airfield sources. In terms of sublime electrical and electronic systems, as well as avionic systems installed on-board of contemporary aircraft, the quality of electricity supplied by ground sources results in their manufacturers facing with high requirements that are contained in relevant standards and regulations. The quality of electricity generated by ground sources and their compatibility have a direct impact, among others, on the calibration of aircraft avionics systems during the ground flight preparation, which directly contributes to the safety of air operations. Therefore, the possibility of constant real-time monitoring of the supplied electricity (specific parameters) enabling immediate identification, recording, adjusting the deviations, hence, preventing damage or improper preparation of an aircraft for flight, becomes a non-trivial issue.
