liftwartbertl 2 Posted December 5, 2017 Share Posted December 5, 2017 Normally for approach not the transition altitude but the transition level is the relevant data to know when to change from QNE to local QNH. Is the Airbus automatically calculating the transition level (based on the TA entered)? Link to comment Share on other sites More sharing options...
Emi 5161 Posted December 5, 2017 Share Posted December 5, 2017 You're talking about the transition altitude fiel on the approach page, right? This value is a company option. Our reference bus had it set to transition altitude, but we had feedback of other pilots in our beta whose busses were set to TL instead of TA. It depends on the company philosiphy of when the alerter should start blinking. Some companies want it to start blinking only when flying on STD below the transition altitude as that would definitely be wrong. In no case however the Airbus will automatically calculate the TL. It is dependant on much more than just the altimeter setting, it also depends on temprature at altitude, etc. The TL is always calculated by the controller and published in the ATIS (or published as a fixed value on the chart, depending on the country). We will consider changing it to Transition Level for the 2018 series. No final choice made yet on this. Link to comment Share on other sites More sharing options...
