Beags - you and me both mate! Also, I think it was Brain who pointed-out the question of monitoring a student ('following-through') during rcvr AAR.
I've found little to no info on the development of rcvr capabilitiy so far and, although the current test pilot does have experience of AAR, I'm not sure he is fully up to speed on current techniques, if he is on procedures.
I'm sure the development will be complete before delivery....
On the other hand - it won't matter to the RAF - they'll just need to know how to wind the hoses in and out!
