But it seems so incongruous to use a modern fj with Cobhamesque ifr. Why not buy the full kit, kc-xxx included.
That's about as logical as having to buy a new hangar because you didn't check whether the aircraft you bought would actually fit..... No-one's made that mistake, have they.....
Remind me how big the Timmy hangar is at RAF Mount Pleasant - and the wingspan of the Wanderer?
Modification / certification and training costs associated with fitting a heavy piece of LeMayesque irrelevance to the CC150T would be huge. It wouldn't even be possible on the CC-130H....
As for re-plumbing the F-35A to take a probe, anyone who believes
"It’s a relatively easy … doable change.”
is probably equally interested in buying London Bridge
!! Or has never studied the words of Miss M Rice-Davies.....
