New advice on when to switch the transponder from SBY to ALT or ON
From
http://www.pilotweb.co.uk/news_story.cfm?id=3043
Pilots are being asked to change the way transponders are used while in the circuit for a UK airfield.
The CAA says that, with immediate effect, you should now select and transmit code 7000 with altitude reporting (Mode C), if fitted, while airborne at all times other than the following, when:
- Air Traffic has allocated a different code;
- a special-purpose code (such as the distress code of 7700) is more appropriate;
- the aircraft is operating within a visual circuit and local procedures require the transponder to be set to Standby.
The change is a result of the increasing use of airborne collision avoidance systems (ACAS) in commercial aircraft.
