Abstract: A time-of-flight laser distance device includes a laser transmitter, a laser pulse return detector to receive reflected laser pulses, and comparators with respective first and second trip levels. A preliminary distance to a target is based on a linear ramp as a function of lapsed time from laser pulse generation through an effective time period wherein an associated return pulse is detected. Time-of-flight values associated with a leading edge of the return pulse are obtained at each of the first and second trip levels. A time difference is determined between the obtained values, and a correction factor is applied with respect to the preliminary measured distance based on the determined time difference. A dual ADC may be used wherein the leading edge of the return pulse is calculated by measuring a slope associated with the time-of-flight values and extrapolating a slope origin to a zero crossing point.

Abstract: Systems, computer program products, and methods for displaying navigation performance based flight path deviation information during the final approach segment to a runway and during landing of non-precision flight modes are provided. Improved graphical depictions of navigation performance based flight path deviation information provide pilots and flight crew members with clear, concise displays of the dynamic relationship between ANP and RNP, mode and aspect of flight and related procedures, intersecting flight paths, and current actual flight path deviation from a predefined flight path during the final approach segment to a runway and during landing. For example, an enhanced IAN display may include NPS-type deviation scales to show RNP/ANP relationships and predetermined RNP markers to alert the pilots and flight crew members that the FMC has transitioned from an NPS display for RNAV (LNAV/VNAV) flight procedures to an enhanced IAN display for a non-precision (non-xLS) approach and/or landing.

Abstract: Methods and apparatus are provided for optimizing runway exiting. Prior to landing, the pilot may choose to input one or more new landing parameters. Then, based on current landing parameters (e.g., any new landing parameter(s) and remaining default landing parameters) and the aircraft performance parameters, predicted landing performance can be updated and indicia of the updated predicted landing performance can be displayed to the pilot on an updated airport map and display. The updated predicted landing performance can include, among other things, a display of AUTOBRAKE landing performance. When no further changes to the current landing parameters are desired, the automatic braking system can be set to provide dynamic braking to slow the aircraft to a selected velocity at a selected position on a particular runway.

Abstract: In exemplary embodiments, braking of an airplane is controlled during a rejected takeoff. A rejected takeoff of an airplane from a runway is initiated. Position of the airplane is determined, such as by inputting aircraft position from a global positioning system. Distance remaining on the runway is determined. Deceleration to stop the aircraft in the determined distance remaining on the runway is calculated, and the calculated deceleration is provided to an autobraking system of the airplane. When the aircraft can not be stopped in the determined distance remaining on the runway, a predetermined deceleration that correlates to maximum braking may be provided to the aircraft's autobraking system. The calculated deceleration may be provided to the autobraking system until a pilot takes command of the aircraft's brakes or the aircraft has stopped.

Abstract: The present invention is a laser ranging device that incorporates an internal tilt sensor, an internal temperature sensor, and an internal pressure sensor. The tilt sensor is used to measure the target's vertical angle relative to the horizontal reference plane. Digital signal processing circuitry controls the firing of the laser pulse, calculation of time-of-flight range, measurement of the vertical angle of the tilt sensor, measurement of ambient temperature and storage of tilt sensor and temperature sensor calibration data. The digital signal processing circuitry then provides the user temperature corrected ballistic ranging information, including corrected horizontal range. Additionally, an automatic gain control system minimizes the effects of target to target variance in reflectivity and its associated errors. It is also an object of this invention to electronically minimize errors in the measurement of a vertical angle caused by housing vibration and by temperature variance errors.
