## UAM.IDE.MVCA.140 Fuel/energy measuring and displaying equipment

(a) The VCA shall be equipped with means of measuring and displaying to the pilot in flight the remaining usable amount of fuel/energy.

(b) A conservative estimate of the amount of fuel/energy necessary to complete the remaining part of the flight shall be displayed to the pilot in flight unless provided by other means as per point UAM.OP.VCA.195(a).

## AMC1 UAM.IDE.MVCA.140 Fuel/energy measuring and displaying equipment

EQUIPMENT REQUIREMENTS

(a) The VCA should be equipped with means of:

(1) measuring the remaining usable amount of fuel/energy;

(2) providing a conservative estimate in flight of the amount of fuel/energy necessary to complete the remaining part of the flight based on the approved individual fuel/energy scheme of the operator;

(3) displaying to the PIC the comparison between points (1) and (2) updated at regular intervals, as well as upon request; and

(4) warning the PIC when the amount of fuel/energy necessary to complete the flight estimated in point (2) is greater than the remaining usable fuel/energy measured in point (1).

(b) The estimation in point (a)(2) should:

(1) be updated at intervals to allow the VCA to reach the destination following the actual flight routing with the onset of the warning in point (a)(4);

(2) take into account actual wind conditions, and updated weather information issued through dedicated service providers; and

(3) take into account any existing or possible failure or malfunction of the VCA system or any existing or possible abnormal flight condition.

(c) The VCA should be equipped with an in-flight replanning function that indicates to the PIC the area where a diversion is possible and indicate vectors to a suitable diversion location.

(d) As an alternative to points (a)(2), (a)(3), (a)(4), (b) and (c), the operator may implement a procedure in accordance with AMC1 UAM.OP.VCA.195.
