AF Form 4140: C-130J Inflight Refueling Worksheet Download – U.S. Air Force aircrew and mission planners rely on AF Form 4140 for precise fuel planning during complex special operations missions involving the C-130J variants. This specialized worksheet ensures safe, efficient in-flight refueling (AAR) operations, critical for extending range and supporting special operations forces (SOF) in contested or remote environments.
What Is AF Form 4140?
AF Form 4140, titled Special Operations C-130J Inflight Refueling Worksheet, is an official U.S. Air Force form used primarily by crews operating MC-130J Commando II, AC-130J Ghostrider, and related special operations C-130J aircraft. It supports detailed calculations for fuel loads, burn-off, reserves, and multiple air refueling scenarios.
The form breaks down into structured sections covering:
- Takeoff to EAR #1 (Enroute Air Refueling point)
- EAR #1 to A/R #1 Abort Base
- EAR #1 to EAR #2
- EAR #2 to A/R #2 Abort Base
- EAR to Destination
Key fields include aircraft configuration, gross weights, temperature deviations, enroute fuel, reserves (including CAT I), identified/unidentified extra fuel, recovery fuel, and planned onloads. Notes on the form clarify exclusions like approach fuel or STTO (Start, Taxi, Takeoff) while including standard approach allowances (often ~700 lbs).
It works alongside master flight plans and is referenced in technical manuals such as DAFMAN 11-2EC-130JV3.
Why This Form Matters for Special Operations?
The C-130J family, especially MC-130J and AC-130J variants under Air Force Special Operations Command (AFSOC), performs infiltration/exfiltration, airdrop resupply, and aerial refueling of SOF helicopters and tiltrotor aircraft in low-visibility, politically sensitive areas.
In-flight refueling extends mission endurance far beyond internal fuel capacity, enabling long-range clandestine operations. AF Form 4140 helps crews:
- Calculate precise fuel requirements to avoid shortages.
- Plan for multiple refueling events and abort scenarios.
- Account for variables like temperature deviations, reserves, and wing relieving.
- Ensure compliance with minimum landing fuel, holding, and alternate requirements.
Proper use reduces risk during high-stakes missions where margins are tight.
Who Uses AF Form 4140?
- Pilots and copilots on C-130J special operations aircraft.
- Combat Systems Officers (CSOs) and mission planners in AFSOC units.
- Loadmasters and aircrew involved in fuel management and tanker/receiver operations.
- Units at bases supporting MC-130J and AC-130J missions, such as those under the 1st Special Operations Wing.
It is a mandatory planning tool referenced in flight operations manuals for EC-130J, MC-130J, and related variants.

Best Practices:
- Use it in conjunction with approved Computer Flight Plans (CFP) and aircraft-specific technical orders.
- Fill out leg-by-leg calculations starting from takeoff gross weight through each refueling and destination phase.
- Double-check notes for items like CAT I reserves, approach fuel exclusions, and negative fuel adjustments (which require adding to required ramp fuel load).
- Maintain a copy for mission records and post-flight review.
Always consult the latest DAFMAN 11-2 series publications or unit standardization/evaluation for current procedures, as aviation guidance evolves.
