Genghis - Two refuels with full load for most of a ten hour flight. One refuel for an air to air load. Sorry for not getting specific before
In large exercises, what they do is take off at the base, drop bit of their load at one corner of the country (say the desert of Rajasthan), go to another (Agra), refuel, go to a third (Hyderabad) at a second range, go to the center (Gwalior) and meet the same refueller and then land back at base. With six air to air missiles remaining.
PT6ER - The nozzles have a selector switch on the throttle, and when pressed, the nozzles respond to stick input. The degree is decided by the computer, not the pilot.
