Under what condition is a fuel emergency declared according to GM4 UAM.OP.VCA.191?

A fuel emergency is declared if the final fuel/energy reserve can no longer be protected in flight.

Does the guidance require that the final fuel/energy reserve remain after landing from any point along the route?

Yes, the flight is planned so that from any point along the route a safe landing can be performed with more than the final fuel/energy reserve remaining after the landing.

Q: What is the objective of the final fuel/energy reserve protection?

To ensure that a safe landing can be performed when unforeseen circumstances may not allow the completion of the flight as originally planned.

Q: How is the flight planned to protect the final fuel/energy reserve?

The flight is planned in such a way that allows from any point along the route a safe landing to be performed with more than the final fuel/energy reserve remaining after the landing.

FINAL FUEL/ENERGY RESERVE

(a) The objective of the final fuel/energy reserve protection is to ensure that a safe landing can be performed when unforeseen circumstances may not allow the completion of the flight as originally planned.

(b) For that purpose, the flight is planned in such a way that allows from any point along the route a safe landing to be performed with more than the final fuel/energy reserve remaining after the landing. If the final fuel/energy reserve can no longer be protected in flight, then a fuel emergency is declared.
