Cpl Roger Heal, based at RAF Waddington in Lincolnshire, has been remanded in custody over the allegations.
An RAF spokesman said they were unable to supply details of the charges, or Cpl Heal's age and background.
Cpl Heal will face a hearing in Colchester on Tuesday.
He worked with air cadets, scouts and civilian sports clubs, mainly in the London, Thames Valley, Cheshire and Northumbria areas, from 2001 to 2014.
His arrest followed an investigation by a dedicated Royal Air Force Police sexual offences and child abuse investigation team.
The Service Police Crime Bureau said anyone with information on crimes of this kind should contact them.

Downing Street said "good progress" had been made on the UK's proposals but there were still "difficult issues" to resolve.
The prime minister's spokesman said there would be "substantive discussions" on the reforms instead.
The UK's PM has promised an in/out vote on EU membership by the end of 2017.
The prime minister is said to want to hold an early vote but he has said he will not set the timing of the poll until the negotiations, on Britain's terms of membership of the 28-member bloc, are concluded.

Mr Cameron spoke to German Chancellor Angela Merkel by phone on Thursday to discuss the renegotiation efforts.
After the call, Downing Street said: "The prime minister explained that his priority is to get the substance right, underlining the need for legally binding, irreversible changes.
"He noted that the scale of what we are asking for means we will not resolve this in one go and consequently he did not expect to get agreement at the December European Council.
"Instead, we should keep up the pace of discussions and use the summit for a substantive discussion of the proposed changes in each area."
The government had never committed to a deal by December but it is thought that was what the negotiating team had hoped.
BBC assistant political editor Norman Smith said it suggested Mr Cameron was "running into real difficulties" in his renegotiations, in particular over proposals to restrict EU migrants' access to benefits in the UK.
"That has always been a sticking point," he said, adding that European leaders have "serious reservations" about the proposals.
