In the UK there is a discrete frequency allocated for use when approaching or transitting airfields which otherwise have no frequency allocated.
The service is called 'Safetycom' and it's on 135.480 mHz and is strictly for that purpose and NOT for 'air to air' chat.
Surely you have enough frequencies available in your country to be able to allocate a discrete frequency even on 25 kHz channels without using 8.33 kHz ones
