Abstract: A method in a trail aircraft for monitoring the separation distance between the trail aircraft and a lead aircraft during a flight deck interval management paired approach (FIM-PA) procedure is provided. The method includes: receiving an assigned spacing goal (ASG); receiving traffic information regarding the lead aircraft that indicates the position, heading and ground velocity of the lead aircraft; retrieving a predetermined tolerance limit and traffic information regarding the trail aircraft that indicates the position, heading and ground velocity of the trail aircraft; setting a range limit that is at least as great as the absolute limit indicated by the ASG plus the tolerance limit; monitoring the range and ground speed differential between the lead aircraft and the trail aircraft; and generating a caution alert indicator when a monitored condition detected from monitoring the range and ground speed differential indicates a potential problem.

Abstract: Methods and system use blockchain technology for recording information pertaining to the licensing or usage of aviation software products. For example, a method may include: receiving, from a user of aviation software products, a purchase order to purchase a license to use an aviation software product; creating a first block including license issuance information representing issuance of the license to the user; adding the first block to a copy of a blockchain; providing the aviation software product to the user; receiving, from the user, a second block including usage information indicating usage of the aviation software product by the user; and adding the second block to the copy of the blockchain.

Abstract: A method is provided. The method comprises: identifying a vehicle; providing, to a remote processing system, an interval between the vehicle and a preceding vehicle; providing, to the remote processing system, the preceding vehicle identifier; obtaining, on the remote processing system, a location and a direction of the vehicle; obtaining, on the remote processing system, a location and a direction of the preceding vehicle; determining, on the remote processing system, a speed of the vehicle necessary to maintain the interval; and providing, to the vehicle from the remote processing system, the speed of vehicle necessary to maintain the interval.

Abstract: Technologically improved Flight Deck Interval Management Paired Approach (FIMPA) system and methods are provided that provide safe speed guidance to a trail aircraft. The FIMPA system comprises a processor operatively coupled to a memory and a database of aircraft-specific parameters. The processor is configured to: receive instantaneous target traffic state data; receive instantaneous state data of a trail aircraft; process the state data, target traffic state data, and aircraft-specific parameters to determine a safe speed zone to perform paired approach, and a recommended speed; render, on a cockpit display, a paired approach bar (PAB) with indicators for (i) a current location of the target traffic, (ii) a current trail aircraft speed, and (iii) the recommended speed; and wherein the indicators are separate and visually distinguishable from each other; determine a wake risk area; and render the wake risk area in a visually distinguishable manner on the PAB.
