Abstract: An aircraft test system generates stimuli that emulate the stimuli received by an aircraft when in flight is disclosed. The aircraft test system includes a number of instruments for generating the number of processor-controllable instruments for generating stimuli received by an aircraft when in flight. The system also includes a number of instruments that monitor the response of the various aircraft components to the stimuli to which the aircraft is exposed. A processor in response to the output signal from the aircraft components directs the stimuli generating instruments to produce stimuli that emulate those received by the aircraft as it moves through the air. The system thus generates an initial set of stimuli similar to what an aircraft would be exposed to when in flight; monitors the response of the aircraft to the stimuli to which it is exposed; and, in response generates an updated set of stimuli to the aircraft.

Abstract: Temperature measurement with thermocouples is made more accurate, and the cost of disposable thermocouples is reduced by locating the cold junction close to the hot junction, utilizing a thermistor in thermal communication with the cold junction in developing a compensating voltage which varies with temperature as does the voltage produced by the cold junction, and applying the compensating voltage to cancel the cold junction voltage. The presence of radio frequency fields in the region of the thermocouple is detected and utilization of the thermocouple voltage is interrupted in intervals when the interference is greater than some preselected intensity. Further, the thermocouple voltage information is utilized to simulate the resistance a thermistor would have at the temperature represented by the thermistor voltage information and that simulated resistance is applied to instrumentation designed to measure temperature with a thermistor.

Abstract: A modulated VLF signal source has the capability for providing radio sign suitable for performance testing and operator training relative to VLF digital data receiving systems. A number of separately proven components are utilized to implement a relatively low cost, reliable compact and easily transportable system. A digital modulator is driven through suitably adapted microprocessor circuits by selective information stored on floppy diskettes. Operator input commands actuate the modulator to generate representations of data in the continuous shift keying, frequency shift keying, or minimum shift keying output modes to provide a modulated VLF output which can be received by several receive systems. Prolonged data transmissions can be produced by merely selecting the appropriate floppy diskettes to initiate the desired modulated sequences.

Abstract: An inflight IFR procedures simulator for generating signals and commands to conventional instruments provided in an airplane. The simulator includes a signal synthesizer which generates predetermined simulated signals corresponding to signals normally received from remote sources upon being activated. A computer is connected to the signal synthesizer and causes the signal synthesizer to produce simulated signals responsive to programs fed into the computer. A switching network is connected to the signal synthesizer, the antenna of the aircraft, and navigational instruments and communication devices for selectively connecting instruments and devices to the synthesizer and disconnecting the antenna from the navigational instruments and communication device. Pressure transducers are connected to the altimeter and speed indicator for supplying electrical signals to the computer indicating the altitude and speed of the aircraft.

Abstract: Aircraft navigation testing apparatus includes circuitry which produces digital signals on an output bus corresponding to a desired simulation of aircraft glideslope, localizer and very high frequency, omnidirectional (VOR) positions. Localizer and glideslope circuitry respond to the signal on the bus to produce the desired final value signal at the dictated rate. VOR circuitry responds by activating selected switches in a switchbank, thereby programing a conventional VOR generator to produce the VOR signal at the desired rate.
