Flight management system for an aircraft
First Claim
1. A flight management system (FMS), comprising:
- a computer electrically connected to a Multipurpose Control and Display Unit (MCDU) that includes a display screen and an input keyboard;
wherein the computer includes a memory device that includes a stored flight plan having referenced waypoints, including a start point, an end point and intermediate waypoints, each waypoint having a display marker;
wherein the stored flight plan further comprises a predetermined threshold fuel quantity, and a pseudo-waypoint, corresponding to a point where the predetermined threshold is passed;
wherein the computer is configured to execute a fuel consumption monitoring function stored in the memory, the monitory function based upon said referenced waypoints, said pseudo-waypoint, and a specified fuel quantity at the start of the flight plan, the monitoring function comprising;
a threshold-passing estimation function for estimating if a quantity of fuel remaining on board drops below the predetermined threshold value at any point in the flight plan between the start point and the end point, andan inserting unit function for inserting the pseudo-waypoint in the flight plan, corresponding to the point where the threshold is passed.

Abstract
A flight management system for an aircraft, for executing a flight plan comprising referenced waypoints comprising a start point, an end point and intermediate waypoints, the said aircraft having a specified fuel quantity at the start of the said flight plan, executes a function of monitoring the fuel consumption with respect to at least one threshold value. The function comprises an operation for estimating if the quantity of fuel remaining on board drops below a threshold at any point in the flight plan included between the start point and the end point, and inserts a corresponding pseudo-waypoint in the flight plan, corresponding to the point where the said threshold is passed. The inserted pseudo-point is displayed on screens for displaying the flight plan.
