A traffic awareness system displays ground-track heading information on a traffic information screen for other aircraft within the proximity range of the host aircraft. Symbols identify other aircraft locations by position on the traffic information screen and show ground-track heading by display and orientation of a ground-track heading indicator.

A flight display for use in an avionics system has a visual display format to show an enhanced vertical situation of an aircraft. Included is a vertical terrain profile display that displays terrain in front of the aircraft over a selected range and a selected swathe width. The vertical terrain profile display shows a side-on terrain profile view with a digital display of the selected swathe width and a display of range in front of the aircraft. A plan view of the aircraft position is included t...

A mechanical gripper frame unit for devices utilized for lifting parallel-walled containers or the like is disclosed. The novel frame unit or apparatus includes two pairs of rotary locking means disposed thereon for gripping the containers at the upper corners thereof. The longitudinal displacement of the pairs of rotary locking means so as to account for different lengths of containers to be lifted is adjustable by displacing each of the rotary locking mean pairs upon a support frame. When the ...

Systems and methods are provided for integrated control, access, and customizable presentation of navigation related, flight information data on a multifunction display (MFD) within a cockpit. The MFD includes a bezel having controls located thereon which are adapted for controlling display formats, communication devices, navigational devices, and equipment sensors. A display is located adjacent to the bezel. The display is adapted to include at least one display region having navigation related...

A diaphragm-type control valve for installation in drain lines and the like to prevent backflow of water through said drain line which sometimes occurs due to floods and the like. A generally conical tubular body is provided with spiral vanes thereon reinforced with pins to prevent eversion of the diaphragm and apertures are provided at the lower portion of the diaphragm for ventilation purposes.

Four lights are positioned in a square. When a directional correctional signal from an autopilot exists for a predetermined length of time and is above a given magnitude, lights at one or the other sides of the square are lighted to indicate that face and the direction involved. When a pitch correctional signal from the autopilot exists for a predetermined length of time and is above a given magnitude, lights at one or the other ends of the square are lighted to indicate that fact and the partic...

A combination gyrohorizon instrument for aircraft which visually indicates in addition to the dial display presentation of the instrument, by means of signal lamps appropriately placed with respect to the instrument dial and an audible signal indicative of energization of any one of the signal lamps, departures from straight and level flight that exceed reasonable limits of pitch and bank. The signal lamps, indicating "nose up," "nose down," "left wing down" and "right wing down" are in circuits...

A direct gyro-driven instrument assembly for use in an aircraft, providing in a combined display a compass dial, a course heading selector needle, Left-Right indicator, and To-From indicator. The entire instrument assembly of the apparatus is direct driven by a non-slaved gyro and is supported at the front end by ball bearings mounted on a front transparent cover. A double fulcrum caging mechanism, operable from either a compass adjust knob or a course selector adjust knob, provides for caging o...

The digital dual mode VOR indicator is a digital aircraft navigational instrument intended to replace the current dial or needle type VOR indicators. The new indicator has two modes of operation. In the first mode the instrument functions like a conventional omni while during the second mode of operation the VOR indicator constantly reads out the plane's bearing from the VOR station. The bearing information is displayed in a large three numeral, lighted, digital display. The invention covers the...

VOR navigation apparatus is provided with reference and variable phase signals from a received transmission of a VOR station, the phase difference between said signals being proportional to the actual station radial of an aircraft receiving the transmission. The apparatus includes digital phase measurement circuitry for repetitively calculating the digital phase difference between the signals. A solid state display arrangement is responsive to this digital phase difference and has an indicator f...
