A disk has imprinted around its outer periphery various sailboat trim conditions, from beat to run. In the central portion of the disk is an index in the shape of a boat hull. Between this index and the outer periphery of the disk in a rotatable annular index with arrows for indicating the wind direction. By maintaining the central index in alignment with the longitudinal axis of the sailboat hull and rotating the annular index so that it is aligned with the wind direction, one obtains from the ...

A training device for teaching individuals the proper positioning of a sailboat's boom relative to the boat in a given wind. The device has three planar members, a front (base) member indicating wind position and having sailing terms printed therein, a second planar member representing the boat and a third planar member representing the boom of a sailboat. Three axis members interconnect the planar members for proper relative rotation. The first axis member secures the free end of the boom to th...

Stainless steels possessing a superior cold workability and hot workability, which are yet economical. The stainless steels comprise not more than 0.04% carbon, not more than 0.60% silicon, 2.2-3.8% manganese, 2.5-4.0% copper, 6-8% nickel, 17-19% chromium, and the remainder being iron together with impurities. And, not more than 0.002% sulfur is decreased to provide stainless steels which possess superior corrosion resistance, and not more than 0.010% nitrogen are decreased in the stainless stee...

On one side of a portable case are mounted aircraft instruments, a control wheel and a throttle to simulate the instrument panel and controls of an airplane. The control wheel and throttle are movable and interconnected by compound lever mechanism which is connected to actuate the tachometer, the airspeed indicator, the artificial horizon elevationally, the rate-of-climb indicator and the altimeter. The control wheel is connected independently of the compound lever to actuate the turn indicator,...

A visual simulation device for producing pictorial motions of the real wo relative to the inside of a cockpit in terms of roll, pitch, yaw and altitude. A first attitude-direction indicator or "eight ball, " positionable in accordance with computed flight parameters, is located on an instrument panel. The calibrated markings on a second eight ball, driven in parallel with the first, are replaced with a suitably scaled rendition of sky and terrain. An image of a portion of the second eight ball's...

A simulator-display stand, including a control stick and linkage to simulate flight movement with a toy airplane. The linkage includes five elements, two of which includes integral living hinges for transmitting motion of the control stick to parallel motion of the airplane in an easily manipulated, inexpensive and exciting fashion.

An entirely mechanical VOR instruction device suitable for use in training pilots and student pilots in the use of VOR equipment is disclosed. An OBS control knob through a first mechanical linkage controls a course selector dial, a to/from indicator, and a right/left indicator. In addition, an aircraft position simulator arm, through a second mechanical linkage, controls the to/from indicator and the right/left indicator. In operation, after the device is initially set up, movement of the aircr...

A flight simulator instrument trainer has operational controls and instruments similar to a conventional aircraft. An AC driven position simulator moves a simulated station position according to simulated power, attitude, flap condition direction and distance traveled to control simulated ADF, ILS and VOR instruments. Angularly offset phases are generated and are provided to potentiometers on directional instruments. Wipers on the potentiometers move with simulated direction indicators. Signals ...

A seat cushion for providing realistic acceleration cues to an aircraft simulator pilot. A plurality of contiguous seat cushion compartments with each including an air cell with a non-compressible surface underneath the air cell are provided with apparatus for separately controlling the pressure in the air cells. Apparatus are provided for initially controlling the air pressure in the air cells to allow the two main support areas, the tuberosities, of the simulator pilot to touch the non-compres...

A navigation training device for use with any pilot training text on radio navigation, the device has a visual representation of three actual aircraft instruments with movable parts to simulate the actual related readings on the instruments. A set of instructions are provided to instruct the student in the operation of the training device.
