Building a new aerodrome

[nomorecatering]

I was asked a question the other day, about building a new aerodrome.

Is there any restriction on the distance between aerodromes, if both are to have instrument approaches......that is there is an established aerodrome with an instrument approach and ou wat to build another.

Was I was groing up it seems to be 10 nm. Is there a manual that spells out the conditions?

I wonder if CASA might have the answer.

Interesting question and I too would be curious to the answer.

Thought: Tullamarine and Essendon are 3nm from each other from memory and I wonder how that works! :ugh:

What about Hobart and Cambridge? - they even sort of 'share' the ILS approach.

What went before, and what would be allowed today could be quite different. The law of precedent is unlikely to apply. Suggest you dig around the MOS (Manual of Standards) and ICAO documentation on instrument approach criteria. That's the basic compliance stuff.
Then find out from the city or shire council, environmentalists etc what they say. Then the local ratepayers. If it is a new airfield, what part of the word 'NO' do you not get?
