I tend to just ignore these things and start when I feel it's needed, but am risking possible consequences like fines from the airport.
that’s all nice, but do those airport authorities switch off their ac and heating for the environment/noise? Unless the airport provides ground air of a temperature that keeps the cabin comfortable summer and winter my tail will be making noise.
