METHODS AND SYSTEMS FOR MANAGING AIR TRAFFIC
First Claim
1. A method of negotiating air traffic trajectory modification requests received from multiple aircraft that each has trajectory parameters comprising altitude, speed and lateral route thereof, the method comprising:
- transmitting from at least a first aircraft of the multiple aircraft at least a first trajectory modification request to alter the altitude, speed and/or lateral route of the first aircraft;
performing a first conflict assessment to determine if the first trajectory modification request of the first aircraft poses a conflict with the altitudes, speeds and lateral routes of any other of the multiple aircraft;
granting the first trajectory modification request and notifying the first aircraft of the first trajectory modification request being granted if a conflict is not identified by the first conflict assessment step, or not granting the first trajectory modification request and notifying the first aircraft of the first trajectory modification request not being granted if a conflict is identified by the first conflict assessment step; and
thenif the first trajectory modification request was granted, monitoring the altitude, speed and lateral route of the first aircraft to assess whether the altitude, speed and lateral route of the first aircraft complies with the first trajectory modification request;
orif the first trajectory modification request was not granted, placing the first trajectory modification request in a queue, periodically processing the queue to perform at least one subsequent conflict assessment to determine if the first trajectory modification request of the first aircraft still poses a conflict with the altitudes, speeds and lateral routes of any other of the multiple aircraft, and then granting the first trajectory modification request and notifying the first aircraft of the first trajectory modification request being granted if a conflict is not identified by the subsequent conflict assessment step.

Abstract
Methods and systems suitable for negotiating air traffic trajectory modification requests received from multiple aircraft that each has trajectory parameters. The methods include transmitting from at least a first aircraft a first trajectory modification request to alter the altitude, speed and/or lateral route thereof. A first conflict assessment is then performed to determine if the first trajectory modification request poses a conflict with the altitudes, speeds and lateral routes of other aircraft. If a conflict is not identified, the first trajectory modification request is granted and the first aircraft is notified of the first trajectory modification request being granted. Alternatively, if a conflict is identified, the first trajectory modification request is not granted and the first aircraft is notified thereof. If the first trajectory modification request was not granted, the first trajectory modification request is placed in a queue, which is periodically processed to perform subsequent conflict assessments.

20. A system adapted to negotiate air traffic trajectory modification requests received from multiple aircraft that each has trajectory parameters comprising altitude, speed and lateral route thereof, the method comprising:
-
means for monitoring the altitudes, speeds and lateral routes of the multiple aircraft; means for transmitting at least a first trajectory modification request from at least a first of the multiple aircraft to alter the altitude, speed and/or lateral route thereof; means for performing conflict assessments to determine if the first trajectory modification request transmitted from the first aircraft poses a conflict with the altitudes, speeds and lateral routes of any other of the multiple aircraft; means for notifying the first aircraft if the first trajectory modification request thereof can be granted on the basis of whether a conflict was identified by the conflict assessments performing means; a queue in which the first trajectory modification request is placed if the first trajectory modification request cannot be granted on the basis that a conflict was identified by the conflict assessments performing means; and means for periodically processing the queue to perform subsequent conflict assessments to determine if the first trajectory modification request of the first aircraft still poses a conflict with the altitudes, speeds and lateral routes of any other of the multiple aircraft. - View Dependent Claims (21, 22, 23, 24)
