Mission Fuel: Fuel Check

Fast, cockpit-ready fuel checks, burn-rate projections, reserve timing, mission planning, IFR climb math, and FAF-to-MAP timing—with no ads or subscriptions.

Mission Fuel is a fast, no-frills fuel-management tool for pilots who need reliable numbers in the cockpit—not a cluttered flight-planning suite. Originally designed around the needs of military rotary-wing aircrew, it works equally well for fixed-wing and helicopter pilots who want a clear picture of their fuel state.

FUEL CHECK Start the timer with your current fuel load and check in throughout the mission. Mission Fuel calculates your cumulative average burn rate, projected burnout time, and estimated time to VFR and IFR reserves. View times in local or Zulu time, set a bingo fuel threshold, and receive a clear visual warning when you reach it. Enable Precise Fuel Calculations when you want one-pound fuel increments instead of five-pound increments.

FUEL CONVERSION Quickly convert between pounds and gallons using the standard Jet A conversion of 6.7 pounds per gallon.

MISSION FUEL PRO Unlock four advanced cockpit and planning tools with one optional, one-time purchase:

CONTINUE TO MONITOR See how much fuel was burned between checks and project your fuel state 15, 30, 45, and 60 minutes ahead based on your current burn rate.

MISSION FUEL PLANNING Enter your planned mission time—or use Syllabus Mode for tenths-of-an-hour training blocks—and your expected burn rate. Calculate the fuel required for the mission, including VFR or IFR reserve options.

IFR CLIMB PERFORMANCE Enter climb speed and required climb gradient to calculate the required rate of climb in feet per minute—quick math for briefings and departure planning.

FAF TO MAP TIMER Enter the FAF-to-MAP distance and groundspeed to calculate the required approach time. Start the oversized countdown at the final approach fix and receive a clear red Missed Approach Point indication when time expires.

BUILT FOR HOW YOU ACTUALLY FLY

• Switch between pounds and gallons throughout the app
• Track external-tank fuel separately from main-tank fuel
• Set optional reminders at your preferred fuel-check intervals
• Use larger cockpit-friendly navigation targets that retain their position on smaller screens
• Keep every number on your device—no accounts or cloud sync
• Use a clean, high-contrast interface designed for cockpit readability
