Abstract

A device for aiding the piloting of an aircraft during a final approach phase includes a flight management system and an approach selecting device for automatically selecting an approach to be used during landing of the aircraft. A method for aiding the piloting of an aircraft includes automatically selecting an approach to be used during landing of an aircraft by selecting an approach with the smallest decision height that can also be technically implemented by the aircraft.

Claims

1. A method for aiding the piloting of an aircraft during an approach final phase for a landing at an airport, the approach final phase being implemented according to one of a plurality of different approaches, each approach defining a decision height, the method comprising, the following steps carried out by a flight management system on the aircraft and devices connected to the flight management system:

allowing a crew member to select a landing way of the airport that will be used during the landing;

extracting the possible approaches for the selected landing way from a database, the extracted possible approaches including predetermined characteristics for the possible approaches, including the decision height defined by each of the possible approaches;

automatically selecting an approach for the landing on the selected landing way, wherein the automatically selected approach is selected from amongst the number of possible approaches for the selected landing way, wherein the selected approach (i) presents the lowest decision height of possible approaches; and

(ii) is technically capable of being implemented by the aircraft, wherein the determining of whether a selected approach is technically capable of being implemented further includes checking if a detection device likely to detect signals that have to be used during the selected approach is available on board the aircraft, and checking if this detection device is suitably detecting the signals; and

using the automatically selected approach to activate an approach which will effectively be implemented by the aircraft.

2. The method according to claim 1, wherein automatically selecting the approach for the landing further comprises:

selecting an approach that presents the lowest decision height from among the possible approaches;

checking the aircraft equipment to verify that the selected approach can be technically implemented by the aircraft; and

when the selected approach cannot be technically implemented by the aircraft, repeating the selecting and checking steps in an ascending order of decision height until a selected approach can be technically implemented.

3. The method according to claim 1, wherein automatically selecting the approach for the landing further comprises:

initially selecting each of the possible approaches that can technically be implemented by the aircraft; and

finally selecting an approach that presents the lowest decision height from the initially selected approaches that can be technically implemented.

4. The method according to claim 1, wherein automatically selecting the approach for the landing further comprises:

receiving a recommended approach from an air traffic controller via a communication device;

sorting the possible approaches into a list in which the approaches have increasing decision heights and the recommended approach is placed at the beginning of the list; and

finally selecting a first approach in the list that can be technically implemented by the aircraft.

5. The method according to claim 1, wherein automatically selecting the approach for the landing further comprises:

receiving a recommended approach from an air traffic controller via a communication device;

initially selecting each of the possible approaches that can technically be implemented by the aircraft;

when the recommended approach can be technically implemented by the aircraft, finally selecting the recommended approach; and

when the recommended approach cannot be technically implemented by the aircraft, finally selecting an approach that presents the lowest decision height from the initially selected approaches.

6. The method according to claim 1, wherein using the selected approach further comprises:

automatically implementing the selected approach.

7. The method according to claim 1, wherein using the selected approach further comprises:

presenting the selected approach to a member of the aircraft crew for validation with a validation device; and

implementing the selected approach if the member validates the selected approach.

8. The method according to claim 1, wherein using the selected approach further comprises:

presenting a plurality of selected approaches to a member of the aircraft crew with a validation device; and

implementing a manually validated approach when the member selects one of the plurality of selected approaches.

9. The method according to claim 1, wherein automatically selecting the approach for the landing further comprises:

sorting the possible approaches for the selected landing way according to at least one of the following criteria;

the type of approach;

or

the approach device.
