A method for managing a premature descent envelope during descent of an aircraft is provided. The method receives glideslope deviation data by an instrument landing system (ILS) onboard the aircraft; compares, by the ILS, the glideslope deviation data to an acceptable band of glideslope deviation values; and when the glideslope deviation data is within the acceptable band, expands, by a terrain awareness and warning system (TAWS), the premature descent envelope to produce an increased premature descent envelope for the aircraft.

A method is provided for monitoring a landing approach of an aircraft. The method includes receiving instrument landing system (ILS) signals; determining a glideslope deviation from the ILS signals; disabling, when the glideslope deviation is less than a first predetermined threshold, at least one glideslope alert function; evaluating a current glideslope condition by comparing a designated glideslope angle to a glideslope check value; and re-enabling the at least one glideslope alert function when the glideslope check value differs from the designated glideslope angle by more than a second predetermined threshold.

An approach is provided for constructing a delivery path that enables a UAV to safely access a delivery surface and avoids restricted access surfaces from the open sky. The approach involves determining at least one delivery path to at least one delivery surface, wherein the delivery path represents at least one three-dimensional variable width path along which an aerial delivery vehicle can access the at least one delivery surface. The approach also involves transecting the delivery path with one or more planar surfaces. The approach further involves determining one or more shapes on the one or more planar surfaces, wherein the one or more shapes represent one or more intersections of the delivery path and the one or more planar surfaces. The approach also involves constructing at least one delivery path data object comprising at least one ordered list of the one or more shapes to represent the delivery path.

A dynamic runway indicator is displayed overlying a conformal runway for assisting a pilot in completing an approach to landing on a runway. The dynamic runway indicator includes a polygon, that by changing position with respect to the conformal runway, provides advanced instrumentation cues to the pilot for adjusting the aircraft flight path to a normal, or recommended, path to the runway for landing, thereby assisting the pilot to improve the accuracy and safety of the approach and landing.

An emergency landing procedure that includes a sequence of control settings is continuously generated. An aircraft is landed, including by using the sequence of control settings and a set of one or more inertial sensors to control an actuator.

A method of autonomous landing of an aircraft in a landing area includes receiving, with the processor, sensor signals related to the landing area via a sensor device; obtaining, with the processor, a template of the landing area in response to the receiving of the sensor signals; matching, with the processor, one or more features of the template with the features of the acquired images of the landing area; and controlling, with the processor, each of the sensor device and aircraft control system independently based on said matching.

Methods and systems are provided for generating an interim route that facilitates navigating a vehicle to an intended destination. One exemplary method facilitating an aircraft landing at an intended destination involves obtaining a current position of the aircraft, obtaining one or more time constraints for the intended destination, determining an interim route from the current aircraft position to the intended destination that veers towards a conditional diversion destination based at least in part on the one or more time constraints for the intended destination, and providing indication of the interim route to an aircraft operator, for example, by displaying a graphical representation of the interim route on a navigational map on a display device.

Embodiments of the present invention provide an alternative distributed airborne transportation system. In some embodiments, a method for distributed airborne transportation includes: providing an airborne vehicle with a wing and a wing span, having capacity to carry one or more of passengers or cargo; landing of the airborne vehicle near one or more of passengers or cargo and loading at least one of passengers or cargo; taking-off and determining a flight direction for the airborne vehicle; locating at least one other airborne vehicle, which has substantially the same flight direction; and joining at least one other airborne vehicle in flight formation and forming a fleet, in which airborne vehicles fly with the same speed and direction and in which adjacent airborne vehicles are separated by distance of less than 100 wing spans.

A landing receiving apparatus for aircraft landing, and a control method thereof are provided, in which the landing receiving apparatus includes a flight management system (FMS) which is inputted with, by a user, destination airport, destination runway, and a receiver mode, a data storage portion which stores approach path data for landing of the aircraft; a receiver portion which calculates aircraft position information by using Global Navigation Satellite System (GLASS) signals and Satellite-Based Augmentation System (SBAS) signals transmitted from an antenna portion, when a receiver mode inputted by a user is a GNSS/SBAS combination mode, and a landing guidance information generating portion which generates landing guidance information by using approach path data corresponding to a destination airport and a destination runway inputted by the user, and the aircraft position information, and transmits the generated landing guidance information to the FMS.
