All SID's are 5000'???
e.g. Sampton departure off 08R LGW
The SID has an intermediate 3000' level off. The engine noise is noted when having retracted the flap and maintaining 250 knots, the controller cancels the restriction and the pilots accelerate at 3000' in a level flight profile.
STN Compton 3R SID has a clearance limit of 3000'.
