Hey everyone had a quick question relating to the departure (SID)
When you choose a departure it may have a waypoint with a alternative altitude attached to it i was wondering if you had to follow these altitude restrictions or can you simply just ignore them and fly straight up to your deserted altitude!
Hopefully i can get a response to my questions thank you :)
From my expreince 99% of the time these restrictions on SIDS are ‘at or above’ ones meaning they are the minimum altitude to pass the waypoint, with the maximum being unlimited (or limited by ATC climb clearance where applicable).
Only way to tell what kind of altitude limit it is is using IRL charts though.
For some more information on what the altitude restrictions mean, please see the post below:
Please don’t do this. A “check in” is all that is needed. The controller responding “radar contact” gives you permission to fly your flight plan and altitude of your choice. The radar controller will issue you an altitude restriction if a potential conflict exists.
Asking for an altitude is unnecessary on departure and just adds unnecessarily to the controllers workload.
