1. Are you planning to use a TRA? E.g. ED-R-302 for GINI Anchor, a typical German AARA.
2. KC-135 speed would be around 280 KIAS, 210 is way too slow!
3. 30 miles is too early for the tanker to control all comms unless in a dedicated TRA.
4. MARSA would only be acceptable once the receivers were visual with the tanker, at which point they should be pushed to the boom freq. with SSR at Sby.
5. Typically, in an AARA the formation will fly a racetrack pattern. E.g. in GINI Anchor, 34 x 14 nm with left turns. Minimum block for a formation refuelling at FL290 would be FL270B300 as in GINI.
6. 10 min is probably all the time that the F-16s would need once with the tanker.
