collision or converted rapidly. Students should be prepared to successfully complete all
conversion intercepts with DB off.
Tactical Conversion Rules
There are only four rules that apply to tactical conversions at VT-86:
The maximum cut allowed is 90º plus .1 IMN speed increase.
The bogey bearing must be within the scope limits no later than 20 nm.
The conversion is over by 14 nm. There will be no reconversions inside 14 nm.
However, inside of 14 nm, the fighter may turn to: 1) attack heading (goal achieved), 2)
collision heading (not at goal TA within rounds and TA is drifting in the wrong
direction, i.e. blow through), 3) 0 cut, 4) keep the bogey on the scope or 5) lead for a F-
The bogey must then be successfully attacked and reattacked.
Sparrow Attack from Head-On / Advantages of low TA
The Sparrow missile guides more accurately with higher rates of closure caused by a low
target aspect situation. The highest probability for a Sparrow kill is from the head-on (0° TA)
position, which also allows for a maximum range Fox-1 shot. No lead computation or turn to
lead from collision is required and the missile will require minimum inflight guidance
corrections. However, should the Sparrow not guide to a kill, the lack of lateral displacement,
coupled with a small radar cross-section and vulnerable fighter position, could limit the fighter's
success later in the intercept.
