If the fuel/energy measuring and displaying equipment does not provide conservative estimations in-flight, what must be done during pre-flight planning?

The operator's policy and procedures should ensure that conservative estimations are made during the pre-flight fuel/energy planning for specified check points along the planned route, including the amount of fuel/energy necessary to complete the remaining portion of the flight to the destination vertiport or the VEMS operating site, and the amount of fuel/energy necessary to reach a vertiport or a diversion location along the route.

Q: What should the pilot-in-command monitor in-flight regarding fuel/energy, and what should it be compared against?

The PIC should monitor in-flight the remaining amount of usable fuel/energy and compare it with a conservative estimate of the fuel/energy necessary to proceed to the destination vertiport or the VEMS operating site where a safe landing can be performed.

Q: What is the purpose of retaining fuel/energy data and estimations for 5 years?

The data and estimations are retained to be used as a follow-up to incidents and other technical reports and to identify and make adjustments to the fuel/energy system performance.

ED Decision 2025/010/R

IN-FLIGHT FUEL/ENERGY CHECKS

(a) The operator’s policy and procedures should ensure that the PIC monitors in-flight the remaining amount of usable fuel/energy and compares it with a conservative estimate of the fuel/energy necessary to proceed to the destination vertiport or the VEMS operating site where a safe landing can be performed, either through dynamic checks or checks at regular intervals of the fuel/energy measuring and displaying equipment.

(b) If conservative estimations of the fuel/energy necessary to complete the remaining part of the flight are not provided by the fuel/energy measuring and displaying equipment in-flight, the operator’s policy and procedures should ensure that the following conservative estimations are made during the pre-flight fuel/energy planning for specified check points along the planned route:

(1) amount of fuel/energy necessary to complete the remaining portion of the flight to the destination vertiport or the VEMS operating site; and

(2) amount of fuel/energy necessary to reach a vertiport or a diversion location along the route.

The specified check points should be regularly distributed along the planned route to allow for the safe management of the fuel/energy in-flight.

The PIC should monitor in-flight the indications of the fuel/energy measuring and displaying equipment to establish the remaining usable amount of fuel/energy as the VCA proceeds towards the destination vertiport or the VEMS operating site and, at the specified check points, compare this amount with the conservative estimations for those check points made during the pre-flight fuel/energy planning.

(c) The relevant fuel/energy data and estimations should be recorded by the operator’s safety management system and retained for 5 years to be used as a follow-up to incidents and other technical reports and to identify and make adjustments to the fuel/energy system performance.
