The transition you give as ATC in IF has nothing to do with transition altitude and level. The transition you give as ATC is the lowest altitude you want that traffic to pass through your zone - i.e. if he stays above that altitude he won’t interfere with your landing and take-off traffic.
Funny… I don’t think we have that here… Perhaps just for the FAA? There’s only an advisory note to pilots in the AIP to not climb above 3000ft while departing as that may cause collision with arriving aircraft
As noted, all constraints (speed and altitude) are in the SID and STAR charts. I can see they are there in the charts for WSSS, this is what the pilots look at and follow, and what shows in the FMC when that SID/STAR is selected (obviously any specific ATC instruction may override that). They are designed so arriving and departing traffic do not conflict.
Yes. Those are the charts the pilots use to plan the departure and arrival, and also tie in with the constraints that the FMC includes when selecting any particular SID and STAR.
I was addressing your point about “There’s only an advisory note to pilots in the AIP to not climb above 3000ft while departing as that may cause collision with arriving aircraft”. That is irrelevant. What is relevant is what is in the charts and the altitude constraints in the charts are far more complex and SID/STAR specific.
Actually you’ve strayed off-topic more than I did… It was originally about transitions, not SIDs and STARs… I know the FAA has transition for GA aircraft to pass through busy airspaces but for us really the TL is only meant for the pilot to change the QNH to Std.
It is but you said transition level in your post not transition altitude. TA is for departure and when you go from local pressure to standard, transition level is for descent when you go from standard to local pressure. Don’t mix the terms transition altitude and transition level, they are not the same thing.
The local pressure is the pressure at the relevant departing/arriving airport. For GA when you don’t go above the TA you can get an area QNH you use to set the altimeter.
TA and TL vary all over the world. They can be as low as a few thousand feet (AMS has a TA on the SID charts of 3000ft) or as high as 18,000ft (in the US TAs are 18,000ft). TL is usually higher than the TA.
