As many will know, the Transition level (When altitude readouts change from ft to Flight Level) in the US is FL180/18000ft. This is what is followed in IF, in the whole of the world. The problem is the transition level varies heavily in different countries:
UK (London): 3000 in open airspace, 6000 in the London airspace, sometimes different in airport CTRs (East Midlands for example is 4000)
France (Paris): 4000 (unless different on airport charts)
Malaysia, Singapore (Singapore and KL): 11000
Australia (Sydney): 10000
The Netherlands (Amsterdam): 3000
Germany (Amsterdam): 5000
Yet 18000 is used all of the time. So what about the altitude speech and selection changing according to the flight level? Even if it is just a general for each region (not using the airport charts).
Nice idea! I also think that it needs to be lower than FL180 in Infinte Flight because realistically not many players fly above 18,000 feet on live because airports are relatively close in comparison to global flights so there isn’t much need to go far above FL100, and therefore not many people would be using the ‘Center’ ATC frequency in IF if they followed the FL180 transition. I think that it should be lowered to FL100 to contact ATC Center in IF
