Pointer,
trust me {and so ya should ;-)) } we don't try to make life hard for ya. If ya get a stepped climb that seems pointless then bear in mind what PPrune Radar said. Depending on where we (controllers [and i use the term loosely]) work we have lots of different things to take into account. Not speaking from personal experience now but, i know there are units in the UK that have to work (literally) under the shadow of others. These units have to give you stepped climbs due to traffic in and out of other airfields and also to do with the constraints of controlled airspace. LCA is a prime example where the whole system was designed for low performance aircraft. The newer aircraft, such as yours, out-perform the airspace allowed for them and therefore are pushing the limits of the CTR as it exists now. If in the UK we could poach more airspace for you from the private flying fraternity then maybe we could get somewhere toward alleviating the problem for you. Until that happens please bear with us as we are trying our best with the tools and space available to us.
Spot the difference next time you fly to LHR, where the aim is to give you a Continuous Descent (and therefore low noise) Approach as opposed to LGW where it always seemed to be an 'as low as early as possible approach'.
