We all have an equal right to be there.
Which is exactly the sort of attitude that makes some GA pilots unwelcome at busy airports.
And I say that as one who has spent hundreds of happy hours in little aeroplanes as well as Her Majesty's fleet. Some understanding of the other guy's problems makes for an easier life for all.
While I don't condone the pilot of a commercial jet making an issue of his displeasure on the R/T, how else is it to be made clear to some occasional visitor anxious to brandish his civil rights that he is being the proverbial ache in the fundament?
Obviously some of you have little concept of the time pressures many short haul commercial pilots operate under. Do you really think you should have equal status with a large jet with a slot time for take off?
