Hi Scifi,
I know - it is very sad... But people have to eat! So I respect this.
But when people keep telling me that us light GA don't pay... It does annoy me quite a bit because we do pay, at Biggin its presently around £15 for a touch and go, and £30 for a landing of a PA28 that's definitely not insignificant. Most other airfields that I know of charge £5 per T&G and £10-£15 per landing! As I mentioned above, I think my average payments are around £2k per year to the airfield in landing, approach, and TG fees... Although - it is true that they don't charge UKBA Customs fees when coming back from abroad.
Anyway - its just a shame, because now its just Southend that will accept GA and has IAP, hard runway and lights within an acceptable distance from London...
