Definitions
- the present invention relates to a method and a device for providing to a pilot of an aircraft which is provided with a plurality of engines, information relating to the engines of said aircraft.
- the present invention aims to provide information on the maximum power that the aircraft engines can deliver for particular outdoor conditions (temperature, altitude).
- each engine is associated for each certified regime maximum thrust, in particular a maximum thrust of so-called “cold day” blowing. This maximum thrust is maintained until a fictitious outside temperature called “break point".
- an exhaust gas temperature EGT type Exhaust Gas Temperature
- EGT exhaust Gas Temperature
- This temperature (EGT) is kept constant, which corresponds to a motor thrust which decreases when the outside temperature increases. This temperature (EGT) is measured via a probe and is used to monitor the deterioration of the engine in service.
- a temperature limit value (known as "red line” in English, that is to say red line) is defined during the engine certification tests and is declared to the certification authorities. When an engine in service reaches this temperature limit, it must be removed for reconditioning, or if possible, reprogrammed for a lower certified engine speed, corresponding to a lower exhaust gas temperature. which of course has the effect of lowering the maximum thrust that the engine can then provide.
- the present invention aims to overcome these disadvantages. It relates to a method for providing a pilot of an aircraft which is provided with a plurality of engines, information relating to the engines of said aircraft, to overcome the aforementioned drawbacks.
- said method is remarkable in that: a) the effective altitude and the effective external temperature of an airport on which said aircraft is located; b) for each of the engines of said aircraft, it is determined, with the aid of said effective altitude and said effective external temperature, an ambient temperature limit for which the engine provides a predetermined maximum thrust (the maximum take-off thrust cold day aforesaid ) if it operates at a predetermined limit value for the exhaust gas temperature (the above-mentioned "red line”value); c) for each of said engines, from the corresponding ambient temperature limit determined in step b), a minimum individual flexible temperature of the engine is determined; and d) from the individual minimum flexible temperatures thus determined for all les engines of the aircraft, a minimum flexible temperature is determined "overall.
- step d it is determined, from said global minimum flexible temperature determined in step d), a maximum available thrust illustrating the maximum thrust that the engines of the aircraft are able to provide at the same time. from said airport to said effective outside temperature.
- the pilot has the maximum thrust that the various engines of the aircraft can provide a given day on a given airport.
- At least one display screen is presented to a pilot of the aircraft, at least the overall minimum flexible temperature determined in step d), and possibly said maximum available thrust.
- the overall minimum flexible temperature determined in step d) is compared with a flexible temperature selected by a pilot of the aircraft for the purpose of regulating the engines of said aircraft;
- the ambient temperature limit is determined as the imaginary external temperature for which, at maximum thrust, the exhaust temperature gas is equal to its limit value.
- T3 is the temperature of the aforementioned breakpoint
- step d) to determine the minimum-overall flexible temperature:
- the minimum maximum individual flexible temperature (corresponding to the lowest engine thrust) is selected as the overall minimum flexible temperature.
- the present invention also relates to a device for providing a pilot of an aircraft which is provided with a plurality of engines, information relating to the engines of said aircraft, for example a transport aircraft.
- said device is remarkable in that it comprises:
- fourth means for determining an overall minimum flexible temperature, based on the minimum individual flexible temperatures thus determined for all the engines of the aircraft.
- said device further comprises:
- the second and third means associated with at least one of said motors are part of a control unit of said engine.

- Figure 2 schematically illustrates a portion of the information obtained through a device according to the invention on a twin-engine aircraft.
- the device 1 according to the invention and shown schematically in FIG. 1 is intended to provide a pilot of an aircraft A which is provided with a plurality of engines 3A, 3B,..., 3n, for example an airplane of twin-engine or four-engine transport, information relating to the engines 3A, 3B,..., 3n of said aircraft A.
- said device 1 comprises, according to the invention:
- each of said means 4A, 4B, ..., 4n is formed so as to determine for the engine with which it is associated, with the aid of the information (actual altitude and actual outside temperature) received from said together 2, an ambient temperature limit known as "OATL" (for "Outside Air Temperature Limit” in English) for which the associated engine provides a predetermined maximum thrust (the usual maximum thrust of cold day off-take) if it operates at a predetermined limit value of EGT (the usual limit value called "red line”);
- each of said means 6A, 6B, ..., 6n is formed so as to determine for the engine with which it is associated, from the corresponding ambient temperature limit received from the means 4A, 4B, ..., 4n to which it is linked, a minimum individual flexible temperature for the 3A motor,
- means 8 for determining an overall minimum flexible temperature, based on the minimum individual flexible temperatures received said means 6A, 6B, ..., 6n via links 9A, 9B, ..., 9n.
- said device 1 further comprises means 10: - which are connected via a link 1 1 to said means 8; and - which are formed so as to determine, using the global minimum flexible temperature received from said means 8, a maximum available thrust illustrating the maximum thrust that the engines 3A, 3B,..., 3n of the aircraft A are able to provide at said airport at said actual outside temperature.
