Name: Fuel Burn – Fuel Timer for Pilots

Author: Freitag

WARNING: The app is intended only as an in-flight aid and should not be used as a primary information source. If the app contains a barometric altimeter, it will not function in a pressurized aircraft and should not be used in a pressurized aircraft.

Your fuel gauge on the wrist: Fuel Burn shows how much fuel you have left —
or how much you have used — while you fly. Everything is calculated from
the flight timer and your aircraft's hourly fuel burn.

GET STARTED (in the Connect IQ Store app: My Device / My Data Fields /
Fuel Burn / Settings)
1. Enter your burn rate, e.g. 15 liters per hour
2. Enter your fuel on board, e.g. 80 liters
3. Start the activity — your fuel counts down while you fly

WHAT YOU SEE
- A cockpit-style fuel gauge from F (full) to E (empty). Green while you
  have plenty, amber when it gets low, red at your reserve
- Your remaining fuel as a large number, e.g. "34.5 L"
- ENDURANCE: how long you can still fly. TO RSV: how long until you reach
  your reserve
- At your reserve, the watch pops up a warning and vibrates

GOOD TO KNOW
- No fuel on board entered? The field simply shows fuel USED instead
- Taxi & run-up fuel can be added automatically when the timer starts
- Pauses don't burn fuel — only timer time counts
- Liters or US gallons
- Your fuel estimate is saved with the activity. After refueling, compare
  it with the real amount and fine-tune your burn rate
- TIP: put the field on a data screen with the single-field layout to get
  the big full-screen gauge. In smaller slots it shows a compact view

All settings live in the Connect IQ Store app on your phone (My Device /
My Data Fields / Fuel Burn / Settings) and take effect immediately — even
in flight.

IMPORTANT — SAFETY NOTICE: This data field is a simple time-based estimate.
It does not measure actual fuel flow or fuel quantity. Do NOT use it for
flight planning, fuel management or any safety-critical decision. Always rely
on your aircraft's fuel instruments, your POH and official flight planning.
