Laryngoscope assembly

A method, apparatus, and computer program product for identifying air data for an aircraft. The lift for the aircraft is identified. The number of surface positions for the aircraft is identified. The angle of attack during flight of the aircraft is identified. A synthetic dynamic pressure is computed from the lift, the number of surface positions, and the angle of attack.

Alternative method to determine the air mass state of an aircraft and to validate and augment the primary method

A method and a system for indicating a target idle running speed, a predicted core speed, a predicted time to running, current engine state or automation modes of an operating aircraft engine, and indicating that the current core speed of the aircraft engine is less than a target idle running speed or is abnormally decreasing towards a target idle running speed. The indicators may be visual or aural. The visual indicators may include graphical or numeric symbols indicating the target idle running speed, the direction of core speed change, the predicted core speed at some future time, or current engine state or automation mode.

Method and apparatus for indicating operational state of aircraft engine

A system and method are provided for automatically alerting a flight crew of an airplane when takeoff is attempted on a wrong runway. Identification data for an origin runway from which takeoff of an airplane is desired is entered via an operator interface. Stored position data for the origin runway is retrieved. Sensed position data for the airplane is input from a plurality of sensors. The stored position data for the origin runway is compared with the sensed position data for the airplane. A determination is made whether the sensed position of the airplane is within a predetermined position difference from the stored position of the origin runway, and a determination is made whether takeoff is attempted. An indication of wrong runway is provided when takeoff is attempted and the sensed position of the airplane is greater than the predetermined position difference away from the stored position of the origin runway.

Wrong runway alert system and method

A navigation performance based flight path deviation display assembly includes a display and a display processor capable of generating an image upon the display. The image includes at least one flight path scale comprising a reference point bounded by end markers extending in at least one of a lateral and vertical direction. The display also includes at least one moveable deviation pointer disposed on the flight path scales. Additionally, the image includes a representation of at least one extendable navigation error disposed on the flight path scale, and extending from at least one of the end markers toward the reference point based upon an actual navigation performance (ANP) and the RNP for the aircraft. The image may also include at least one moveable intersecting flight path pointer disposed on the flight path scales.

Assembly, computer program product and method for displaying navigation performance based flight path deviation information

A numerical input to a computer, such as an input of runway altitude to an aircraft control system, is controlled by a switch having five positions as follows: 'off' for maintaining the current value, 'slow increment' for increasing the value slowly, 'fast increment' for increasing the value more quickly, 'slow decrement' for slow decrease in the value, and 'fast decrement' for faster decrease in the value. A processor monitors the current switch position. Depending on the period that a particular position is selected, the value fed to the control system and shown on a display can be 'bumped' unit by unit (small units for a 'slow' selection, and large units for a 'fast' selection) or scrolled up or down at a rate which accelerates. Bumping is achieved by toggling the knob quickly from the off, or the next closest position, to the desired slow or fast position. Scrolling or 'continuous slew' is selected by maintaining the switch in the desired slow or fast position.

Variable slew selector switch system

An air data computer outputs a data stream indicative of measured airspeed of an aircraft, for use in generating a display of airspeed to a pilot. To correct for the inherent processing delay, a correction factor is added to the data stream, so that the display is more closely related to the actual airspeed of the aircraft at the time of the display. The correction factor can be calculated by determining the average rate of change of airspeed during a preceding time interval and multiplying the average rate of change by the processing delay.
