An integrated and dynamic symmetrical display of flight instruments for universal use in aircraft, wherein key instruments indicating with respect to aircraft direction are specifically arrayed with respect to key instruments indicating aircraft rate, wherein flight under instrument flight rules may be more easily learned, undertaken, and practiced with greater safety and ease of pilot workload, as compared with asymmetrical and random conventional flight instrument displays. Specifically, directional instruments are positioned in an aligned row above similarly arranged aircraft rate instruments for quick, reliable pilot scan and information utilization.

The present invention relates to software for training an aircraft pilot to respond to the failure of one or more engines of a multi-engine aircraft during flight. The software simulates engine failure through the use of software imposed power output limits on the one or more engines for which failure is simulated. In certain embodiments, the software of the present invention sets one or more of the engine condition gauges to a fictitious readings corresponding to readings that would be displayed in the event of an actual engine failure.

A system utilizing a two-circuit vacuum switch to monitor suction in the fuel system between the fuel selector valve and the engine-driven pump and warn the pilot of a restriction in the system or that the fuel tank from which the engine is feeding is exhausted of fuel.

A device is disclosed for training pilots by simulating the operation of gauges in aircraft. The self-contained device can be installed into training aircraft to be used during instruction. Alternatively, the device can be used during classroom and ground school training. A switch box control panel simulates the controls and indicators of aircraft. A logic circuit and program simulate normal operations and common malfunctions of aircraft. During malfunctions the program and circuit will evaluate the pilot's corrective control input, continuing the malfunction if the pilot's response is incorrect. The device's ability to accept inputs and to emulate characteristics of specific aircraft increases the realism of the simulation and training.

An aircraft flight simulator system adaptable to an actual inoperative aircraft not in flight provides instrument displays driven by a computer flight simulator program interacting with inputs from sensors attached to the actual aircraft control system and overlay switches. The computer may also drive visual displays placed in the cockpit windshield and side windows, as well as provide audio output and output for the operation of aircraft jacks to simulate inflight motion. All equipment may be relatively quickly and easily installed or removed so as to make maximum use of an otherwise inoperative aircraft on the ground, and by the use of computer program modifications, may be used to simulate a wide variety of aircraft. Realistic control handling is provided by feedback mechanisms attached to various aircraft control surfaces and the control column and which are coupled to the computer.
