Abstract

A method and device for aiding piloting of an aircraft, during at least one flight phase including piloting steps. The device includes a unit for real-time acquisition of flight parameters of the aircraft, a calculation unit for calculating in real time with the parameters, for each of the piloting steps, a distance between current position of the aircraft and a position along a flight trajectory followed by the aircraft, at which the aircraft will reach the corresponding piloting step. At least one display unit is provided for displaying, in real time, characteristic signs each illustrating one of the piloting steps, the characteristic signs being integrated into the environment viewed with the aid of the screen and being positioned so as to make it possible to locate a place of the environment along the flight trajectory followed by the aircraft, at which the aircraft will reach the piloting step.

First claim

The invention claimed is:

1. A method of aiding piloting of an aircraft, during at least one flight phase including a plurality of piloting steps, a piloting step being a decision step or an action step, the method comprising:
an acquisition step for carrying out real-time acquisition of flight parameters of the aircraft;
a display step for displaying in real time, on at least one screen of a flight deck, a plurality of characteristic signs, each of the characteristic signs illustrating one of the piloting steps, wherein displaying the characteristic signs includes displaying a representation of the predicted flight trajectory of the airplane in a form of a virtual strip and, for each piloting step of at least a decision piloting step and an action piloting step, displaying on either side of the virtual strip a virtual panel including a label that specifies the piloting step and height, pressure altitude, or speed information for the piloting step; and
a calculation step for calculating in real time, with aid of the flight parameters, for each of the piloting steps, a distance between current position of the aircraft and a position along a flight trajectory followed by the aircraft, at which the aircraft will reach a corresponding piloting step, and wherein in the display step the characteristic signs are integrated into environment viewed with aid of the screen and are positioned to locate a place of the environment along the flight trajectory followed by the aircraft, at which the aircraft will reach the piloting step.

2. The method of claim 1 ,
wherein at least one of the piloting steps is defined at a given value of an altitude parameter.

3. The method of claim 2 ,
wherein the altitude parameter is a height relative to the ground, the distance D being calculated, in the calculation step, with aid of the following expression:

D



in which:
Ht is a height relative to the ground and corresponds to the given value of the altitude parameter;
H is a current height of the aircraft relative to the ground;
γ is the current climb or descent slope of the aircraft relative to the ground and is one of the flight parameters; and
D is the distance between the current position of the aircraft and the position of the point along the flight trajectory at which the aircraft will reach the height Ht.

4. The method of claim 2 , wherein the altitude parameter is a pressure altitude, the distance D being calculated, in the calculation step, with the aid of the following expression:

D

Vgnd

in which:
ZPt is a pressure altitude and corresponds to the given value of the altitude parameter;
ZP is a current pressure altitude and corresponds to the altitude parameter;
VZb is a current barometric vertical speed and is one of the flight parameters;
Vgnd is a current speed relative to the ground and is one of the flight parameters; and
D is the distance between the current position of the aircraft and the position of the point along the flight trajectory at which the aircraft will reach the pressure altitude ZPt.

5. The method of claim 1 , wherein at least one of the piloting steps is defined at a given value of a speed parameter, the distance D being calculated, in the calculation step, with aid of the following expressions:
if J ≠0: T =(√{square root over ( A*A− 2* J* ( V−Vt ))}− A )/ J

D=V*T+A/ 2* T*T+J/ 6* T*T*T
if J= 0 and A≠ 0: T =( Vt−V )/ A
D=V*T+A/ 2* T*T
in which:
Vt is an air speed corresponding to the given value of the speed parameter;
V is an air speed of the aircraft;
A is a ground or air acceleration of the aircraft and is one of the flight parameters;
J is a time derivative of the ground or air acceleration of the aircraft and is one of the flight parameters; and
T is the time required to reach the air speed Vt on the basis of the flight parameters of the aircraft.

6. The method of claim 1 ,
wherein in the display step, at least one of the characteristic signs is displayed:
as a conforming view on a screen forming part of a head-up device so that it is superimposed on the place of the environment to be located, which is visible through the screen; and/or
on a screen forming part of a head-down device which displays at least one view of a part of the environment in front of the aircraft and is positioned as a view conforming with the appropriate place of that part of the environment which is reproduced on this screen.

7. A device for aiding piloting of an aircraft, during at least one flight phase including a plurality of piloting steps, a piloting step being a decision step or an action step, the device comprising:
a unit for real-time acquisition of flight parameters of the aircraft;
at least one display unit configured to display, in real time, on at least one screen of the flight deck, a plurality of characteristic signs, each of the characteristic signs illustrating one of the piloting steps, wherein displaying the characteristic signs includes displaying a representation of the predicted flight trajectory of the airplane in a form of a virtual strip and, for each piloting step of at least a decision piloting step and an action piloting step, displaying on either side of the virtual strip a virtual panel including a label that specifies the piloting step and height, pressure altitude, or speed information for the piloting step; and
a calculation unit configured to calculate, in real time, with aid of the flight parameters, for each of the piloting steps, a distance between current position of the aircraft and a position along a flight trajectory followed by the aircraft, at which the aircraft will reach a corresponding piloting step, and wherein the display unit is configured to integrate the characteristic signs into the environment viewed with aid of the screen and to position them to locate a place of the environment along the flight trajectory followed by the aircraft, at which the aircraft will reach the piloting step.

8. An aircraft comprising a device for aiding piloting according to claim 7 .

9. A method of aiding piloting of an aircraft, during at least one flight phase including a plurality of piloting steps, a piloting step being a decision step or an action step, the method comprising:
an acquisition step for carrying out real-time acquisition of flight parameters of the aircraft;
a display step for displaying in real time, on at least one screen of a flight deck, a plurality of characteristic signs, each of the characteristic signs illustrating one of the piloting steps; and
