Just wanted to clarify on this, sorry if OT.
As I said first one takes most efforts. Subsequent ones muat be much easier. Yes, there is a lot of hard work that goes in such flight testing. Nothing is left for chances, nothing is taken for granted. You have to demonstrate every thing. Only sometimes for some test points you can use simulations. For ex if Tejas is certified for IL78 and ADA can show CEMILAC to their satisfaction usong simulations that wake parameters for Su30MKI are within already demonstrated limits of IL78, CEMILAC may give certification for Su30MKI without having to go thru entire test set again. Only a few key flight tests could be enough.
Certification of tanker and the refuelling aircraft is individual. Once done, the aircraft and tanker is okay to fuel from compatible systems.
Thereafter, refueling from another certified specific tanker type may require a practice run or two but nothing much more than that. Experienced pilots may not even need that.
It is basically the mating of the probe with the drogue, establishing a specified fuel transfer rate, and the decoupling.
BTW, CEMILAC OKs only the technical part. The actual flight part of the refueling comes under the ops people, either ADA or the forces.
