Problems solved by technology

In such a situation, if the power is not changed, the aircraft will lose speed while it maintains altitude, or the climb rate will decrease while it maintains speed, which of course can become very dangerous and unacceptable

Embodiment Construction

[0109] exist figure 1 The device 1 according to the invention illustrated in FIG. 1 is a device for detecting and warning of degradation in the performance of an aircraft (not shown), especially a transport aircraft. Although said device 1 is not specifically intended to detect performance degradation due to severe or excessive icing problems on an aircraft, it is particularly intended to detect such performance degradation.

[0110] For this purpose, the device 1 carried on board the aircraft is of the type comprising the following components:

[0111] - information source group 2;

[0112] - a central unit 3 connected to said group of information sources 2 via a connection 4, capable of detecting degradation of said aircraft; and

[0113] - A warning device 5 connected to said central unit 3 via a connection 6 .

[0114] According to the invention, said central unit 3 comprises:

[0115] - means 7 for calculating at least one current weight W of the aircraft;

[0116] -...

Abstract

The method involves calculating an actual mass of an aircraft, a theoretical drag of the aircraft from the mass, and an actual drag of the aircraft. A set of comparisons which comprise a comparison between the actual and theoretical drags is implemented using a comparison implementing unit (10). An existence of the degradation of the performance of the aircraft is determined from the set. An independent claim is also included for a device for detecting and warning degradation of performance of an aircraft.

Description

technical field [0001] The present invention relates to a method and a device for detecting performance degradation of an aircraft. Background technique [0002] It is well known that, despite confirmed compliance with regulations, aircraft, especially transport aircraft, can experience significant aerodynamic degradation without the aircrew's knowledge. This situation can cause a surprise effect which can lead to an inappropriate reaction of the aircrew, thus changing the flight quality even more and the control of the aircraft becoming more difficult when the aerodynamic degradation is significant. [0003] Known causes of performance degradation are specifically icing, icy fuselage on the ground without deicing, snow, freezing rain, application of deicing or anti-icing fluids, insect disturbance on wing leading edges, Parts of the control panel on the wing leading edge or flight surface are missing. [0004] When an aircraft is confronted with one of the aforementioned ...
