The
Js are indeed comming back from theatre...because the job is all but done, most of the the troops are home. A K is staying for one option, for which the J is not cleared. It will be by the end of the year however. I don't know how a K operator can poke fun at an aircraft going U/S.
And Hooker, the prop vibration, at high speed, is a problem but it only effects a couple of seats (those in line with the blades). However, as we normally carry mixed loads it has not caused any major snags. The para doors can now be opened in flight. QQ said that the door weighed too much for one loady to open. However, since they found out that the K door is also above the H&S limit, and fitted a stronger spring, it is cleared for use.
Roboabert, you are right that the US use a different method of achieving the despatch floor angle, and they fly in 2000 ft trail (more wake turb). However, that has nothing to do with the mechanics of CDS. We envisaged using the CDS system, but dropped as an ME/AE at 4000 ft trail. Meanwhile QQ are turning it into son of AE.
