Problems solved by technology

Demonstrating compliance with those regulations is a very expensive process that includes simulations, flight testing, statistics, and analysis.
Because the failure to perform the landing safely can cause catastrophic results, the associated systems have to go through the most rigorous Design Assurance Level (DAL), DAL A.

Embodiment Construction

[0008]While embodiments of the invention may be implemented in any aircraft environment using an autoland system, it is currently contemplated to be implemented in a software partition of an aircraft, where the autoland system is to be certified to a high level of design assurance level (DAL), such as in commercial aircraft. Thus, a brief summary of the contemplated system environment should aid in a more complete understanding.

[0009]Modern aircraft contain avionics systems to perform individual or system functions for the aircraft. Examples of these electronic systems include communications, navigation, the display and management of multiple systems, collision-avoidance, weather radar, and even health and usage monitoring systems.

[0010]One specific avionics system is the flight control system (FCS), a system of flight control surfaces, cockpit controls, engine controls, and the necessary operating mechanisms to control an aircraft's direction in flight. This system allows for contr...

Abstract

A method and system for operating an aircraft having an autoflight system comprising flight guidance functionality and autoland functionality providing input to a flight control system such that both the autoflight and autoland functionality and their corresponding systems are operated at a Design Assurance Level A.

Description

BACKGROUND OF THE INVENTION [0001]In aviation, the autoland system fully automates the landing phase of an aircraft's flight, with the human crew supervising the process. Responding to external stimuli, the autoland system is primarily engaged in conditions of poor visibility and calm or steady winds.[0002]A typical autoland system consists of an instrument landing system (ILS) radio, having an integrated glideslope receiver, localizer receiver, and perhaps GPS receiver as well, to receive the localizer and glideslope signals. The output of this radio will be a “deviation” from center which is provided to the flight control computer to direct the flight control system and aircraft control surfaces to maintain the aircraft centered on the localizer and glideslope. The flight control system will additionally control throttles to maintain the appropriate approach speed. After aircraft wheels-down, the autoland system may also include automatic braking to a full stop, in conjunction wit...
