Abstract

Systems and methods are provided for promoting intersection takeoff awareness. The system includes a database storing runway data that includes identifications and locations of runways, identifications and locations of intersections along the runways, and lengths of the runways, a sensor system configured to generate aircraft position data that includes a current position of the aircraft, a display device, and a controller configured to, by a processor: retrieve the runway data, receive the aircraft position data, identify a first intersection of a first runway as the aircraft approaches the first intersection, determine a runway distance available from the first intersection, and display, on the display device, prior to the aircraft entering the first runway, the runway distance from the first intersection and/or an indication as to whether the runway distance from the first intersection is sufficient for takeoff based on performance parameters of the aircraft and safe takeoff criteria.

First claim

What is claimed is:

1 . A method for promoting intersection takeoff awareness for a crew of an aircraft at an airport, the method comprising:
receiving, with a processor onboard the aircraft, runway data that includes identifications and locations of runways, identifications and locations of intersections along the runways, and lengths of the runways; receiving, with the processor, aircraft position data that includes a current position of the aircraft; identifying, by the processor, a first intersection of a first runway as the aircraft approaches the first intersection based on the runway data and the aircraft position data; determining, by the processor, a runway distance available from the first intersection based on the runway data; and displaying, on a display device onboard the aircraft by the processor, prior to the aircraft entering the first runway via the first intersection, the runway distance from the first intersection and/or an indication as to whether the runway distance from the first intersection is sufficient for takeoff based on performance parameters of the aircraft and safe takeoff criteria: comparing the first intersection with an assigned intersection as stored within a flight management system of the aircraft; determining a computed runway distance between the first intersection and the assigned intersection; and displaying, on the display device, a notification in response to the computed runway distance exceeding an intersection distance threshold.

2 . The method of claim 1 , wherein the displaying step includes displaying, by the processor, the runway distance from the first intersection as a numerical value on the display device in a manner that indicates whether the runway distance from the first intersection is sufficient for takeoff.

3 . The method of claim 2 , wherein the numerical value has a color indicative of whether the runway distance from the first intersection is sufficient for takeoff.

4 . The method of claim 1 , wherein the displaying step includes displaying, by the processor, an alert in response to a determination that the runway distance from the first intersection is not sufficient for takeoff.

5 . The method of claim 1 , further comprising displaying, on the display device by the processor, the identity of the first intersection.

6 . The method of claim 1 , wherein the runway distance is determined in a first direction along the first runway, the method further comprising, by the processor:
determining a second runway distance available from the first intersection as measured in a second direction along the first runway opposite of the first direction based on the runway data; and displaying, on the display device, prior to the aircraft entering the first runway via the first intersection, the second runway distance from the first intersection and/or an indication as to whether the second runway distance from the first intersection is sufficient for takeoff based on the performance parameters of the aircraft and the safe takeoff criteria.

7 . The method of claim 1 , further comprising, by the processor:
comparing the first intersection with the assigned intersection as stored within a flight management system of the aircraft; and displaying, on the display device, a notification in response to the first intersection not matching the assigned intersection.

8 . The method of claim 1 , wherein the display device displays a terrain environment including representations of the first runway and the first intersection, wherein the displaying step includes displaying, by the processor, at least one visual graphic on the terrain environment representing the runway distance from the first intersection and/or the indication as to whether the runway distance from the first intersection is sufficient for takeoff.

9 . The method of claim 1 , wherein the steps of identifying the first intersection, determining the runway distance, and displaying the runway distance and/or the indication as to whether the runway distance is sufficient are all performed while the aircraft is in a designated hold short position.

10 . A system for promoting intersection takeoff awareness for a crew of an aircraft at an airport, the system comprising:
a database storing runway data that includes identifications and locations of runways, identifications and locations of intersections along the runways, and lengths of the runways; a sensor system configured to generate aircraft position data that includes a current position of the aircraft; a display device; and a controller operatively coupled with the database, the sensor system, and the display device, the controller configured to, by a processor:
retrieve the runway data from the database;
receive the aircraft position data from the sensor system;
identify a first intersection of a first runway as the aircraft approaches the first intersection based on the runway data and the aircraft position data;
determine a runway distance available from the first intersection based on the runway data;
display, on the display device, prior to the aircraft entering the first runway via the first intersection, the runway distance from the first intersection and/or an indication as to whether the runway distance from the first intersection is sufficient for takeoff based on performance parameters of the aircraft and safe takeoff criteria;
compare the first intersection with an assigned intersection as stored within a flight management system of the aircraft; determine a computed runway distance between the first intersection and the assigned intersection; and display, on the display device, a notification in response to the computed runway distance exceeding an intersection distance threshold.

11 . The system of claim 10 , wherein the controller is configured to, by the processor, display the runway distance from the first intersection as a numerical value on the display device in a manner that indicates whether the runway distance from the first intersection is sufficient for takeoff.

12 . The system of claim 11 , wherein the controller is configured to, by the processor, display the numerical value in a color indicative of whether the runway distance from the first intersection is sufficient for takeoff.

13 . The system of claim 10 , wherein the controller is configured to, by the processor, display an alert in response to a determination that the runway distance from the first intersection is not sufficient for takeoff.

14 . The system of claim 10 , the controller is configured to, by the processor, display, on the display device by the processor, the identity of the first intersection.

15 . The system of claim 10 , wherein the controller is configured to, by the processor:
determine the runway distance in a first direction along the first runway; determine a second runway distance available from the first intersection as measured in a second direction along the first runway opposite of the first direction based on the runway data; and display, on the display device, prior to the aircraft entering the first runway via the first intersection, the second runway distance from the first intersection and/or an indication as to whether the second runway distance from the first intersection is sufficient for takeoff based on the performance parameters of the aircraft and the safe takeoff criteria.

16 . The system of claim 10 , the controller is configured to, by the processor:
compare the first intersection with the assigned intersection as stored within a flight management system of the air
