In the details of the report (Appendix 7, Annex 8, Figure 4.5) their own figures suggest that at small, "low movement" airfields (they use Dunsfold as an example) the fee will equate to almost £5 per movement.
Can small airfields afford to swallow such a cost? Can they afford to put up their landing fees by a fiver or go non-radio (both putting pilots off visiting and hurting them again)?
They don't seem to think so: "This does not in itself imply that the landing charges under AIP would be unaffordable, just that there would be a discernable impact."
