LOW-LEVEL AND TACTICAL FORMATION
11. NATOPS brief
The T-44/TC-12 uses approximately 600 lbs/hr and 720 lbs/hr respectively, at 500 feet AGL.
Figure D-2 demonstrates how to estimate fuel for the LL route. Use NATOPS performance
charts to determine time/fuel required to climb.
We frequently fly two local IR routes: IR 136 and IR 166. By a Letter Of Agreement (LOA)
with Kingsville, we call them SR 136 and SR 166, but schedule them as VR routes. This
eliminates the required two-hour prior notification to schedule them. We also fly one local VR
route: VR 151. To schedule any of these routes, contact Kingsville Base Operations and ask if
the routes are available (T-45s use them as IR and VR routes). Tell them you want SR
136/166/151 and schedule a block time for the routes. If Kingsville says you need to wait two
hours before you can enter, remind them of the LOA and that we are treating them as SR routes.
You may enter the route any time during your scheduled block, however, you must abort the
route at the end of the block (even if not completed) since Kingsville can schedule T-45s for the
route at the end of our block. IR 147 is also covered by the LOA but is not flown by VT-31.
(This includes IR 136/166 since we fly them as SR routes per the LOA.)
For standardization, all TOTs will be whole times in multiples of
five (i.e., 1000, 1005, 1010, etc.).
For T-44/TC-12 operations, use yellow arcs (530 lbs.) as required reserves and 125 lbs. for
recovery and landing.
Since all routes that we fly are local routes, the flight schedule covers the requirement for a DD
Form 175. Ensure the duty office knows which routes will be flown prior to departure.
