When he pleaded guilty to affray before Judge John Burgess last month, he called him a "prat".
Jonathan Straw, mitigating, had said: "It seems the general consensus is he is, for want of a better word, a prat.
Judge Burgess agreed: "Prat is a good word."
Then, at his sentencing hearing this week, Judge Andrew Hamilton told Wilkinson he had acted as "a complete idiot for a couple of seconds".
He said the lorry driver was not to know Wilkinson was not a criminal who was about to commit a serious offence.
And he ordered the 20-year-old to pay £200 compensation to Mr Hutchinson - not only for the momentary fear but also for reporting him. Wilkinson will have to pay £600 court costs and do 100 hours of unpaid work over the next year.
He offended after being in the RAF for four years.He was not on duty when the incident happened in London Road, Newark, on July 23 last year.
Mark Knowles, who mitigated at the sentencing hearing as opposed to Jonathan Straw at the earlier hearing, said on Wilkinson's behalf: "This was a moment of madness from his point of view."
Wilkinson's flight lieutenant attended court with him.Mr Knowles said any form of custodial sentence would result in his client's discharge from the RAF.
A Ministry of Defence spokesman confirmed after the hearing that Wilkinson, who is based at RAF Coningsby, Lincoln, will be facing disciplinary action as a result of the incident.
