Don't think it has been mentioned before but a application has been lodged with the CAA last November for a RNAV approach www.caa.co.uk/Commercial-industry/Airspace/Airspace-change/Decisions/Blackbushe-Airport-RNAV-instrument-approach-procedures/ . After googling it a RNAV approach is carried out using GPS waypoints and descent paths. It is not as accurate as a full ILS system and the decision height is higher, but it is a hell of a lot cheaper! There seem to be hundreds of these approaches at smaller airports in the US. In the UK Halfpenny Green, Coventry, Sherbun, Booker and Shoreham have also applied. Hopefully will bring in more winter visitors? Rob

Thanks for the info, Rob. It's nearly 20 years since I worked at Aerad, and as you say RNAV approaches are/were very popular over there - looks as though they've taken a while to catch on over here! Regulatory issues, maybe?

Thanks Simon. The Fairoaks/Dunsfold issue was covered a few weeks back... blackbusheairport.proboards.com/post/6348Given some hangars and an engineering facility Blackbushe could be well placed, residents at the Surrey airfields are looking around! The new approach system will be one positive step forward, some more tree cutting on Blackbushe 'east' will be taking place during the next week or two - a requirement with new approach aid I'm advised.

If RNAV approaches are to be published for Blackbushe will full ATC be required?

If RNAV approaches are to be published for Blackbushe will full ATC be required? I believe not, should still be at the pilots discretion? Im guessing that RNAV approaches will not be numerous, and only in bad weather? Rob

That's the point.. what happens if more than one aircraft wish to fly RNAV? Where do they hold and who is responsible for them?

The CAA document here link is worth looking at, as it raises and proposes solutions to the type of questions raised above. One particularly relevant excerpt in Appendix 1: Absence of an Approach Control Service.... Absence of an Approach Control Service
Where an applicant presents an argument that it would not be reasonably practicable to provide an approach control service, safety arrangements shall be developed to make robust provision for no more than one aircraft at a time to use the IAP and any associated holding pattern. Such procedures will need to be properly documented, restrictions made known to users, for example by marking them appropriately on the relevant approach plates, and must be reviewed regularly for their effectiveness as part of an agreed process.

= cost?
