Subchapter 9.3 – Minimum Fuel Declarations

When to declare minimum fuel:
  • You encounter stronger-than-forecast headwinds that reduce ground speed.
  • You are vectored off course or held for traffic, consuming fuel unexpectedly.
  • An engine is running rough, increasing fuel consumption.
  • You discover a fuel leak or crossfeed issue and have lost more fuel than planned.
  • Weather forces a longer approach or go-around, consuming reserves.
How to declare minimum fuel:
Address ATC on your current frequency. Example:
"Zurich Approach, HB-CDA, minimum fuel."
ATC will immediately:
  1. Note your fuel status in their records.
  2. Prioritize your approach and landing.
  3. Minimize vectoring and holding.
  4. Clear airways ahead of you.
  5. Ensure emergency services are on standby.
