There are various types of aircraft that operate into certain London airports, from king air’s to 744’s,all have very different handling characteristics, ie slowing down, speeds on final approach. We all know how congested the London airspace is, and sometimes, as mentioned in previous posts, it is difficult to go down and slow down, especially in the larger jets, ie 6000,descend 3000,level in 10 miles, and reduce speed (from 220-250 assigned speed) to 180 kts………it can be done, but its dirty ie flaps and speed brakes, increasing the noise footprint and fuel burn. i think a good sugestion would be to have ATC controllers on regular jumpseat rides into the airspace they control (if the CAA would allow?!), in order to experience and indeed highlight the problems and visa versa, maybe we pilots should get a chance to see them at work…
