The BDA was an utter sod! I was launched on Q with 3 tanks and 8 missiles to prod the thing, having never had any previous dual or even a brief. Teach yourself BDA prodding wasn't a deal of fun, but eventually I worked out what to do and topped up - then we heard that the Bears had turned for home....
Debrief after RTB- "What's the big deal? A tanker is a tanker"...
Strangely enough, the same ar$e wrote a signal some months later saying that a dual trip with an AARI was essential for KC-135 BDA prodding. In Charlie fit without missiles, no doubt.
A 3000 ft airspace block was always the norm on routine AARAs, but for CARR or en-route trail RVs 2000 ft is surely adequate?
