A method and apparatus for providing mass storage of vocal information by means of a digital communication system for use with a training simulator is disclosed. Unlike prior art analog records and playback systems, such as tapes, etc., the inherent advantages and flexibility available with respect to a digital system including randomly accessible voice messages, convenience of editing the stored data, and management and control by the computational system of the training simulator are available with the present invention. In general, the system of this invention comprises an input device, such as a microphone (30), an encoder (54) for encoding the analog information from the microphone (32) to digital format, a digital processing controller or computer (20) for processing the digital communication data in response to a stored program such that it is suitable for use with the computational system, and a mass storage media (38) for storing the processed digital data. To provide audio response and playback from the stored digital data, the system includes a processor (36) for selectively reading stored bulk data and processing the selected data into a form suitable for decoding, a decoding means (66) for translating the digital data to analog information, and an output device (42) for providing an audio or vocal output to a listener.

Aircraft simulator digital audio system

A digital radar landmass simulator system for an aircraft flight simulator including a mapping radar portion using a computer to transfer pertinent blocks of terrain defining parameters stored in a high volume memory to a high speed memory and a processor accessing the high speed memory for collecting those parameters which correspond to each radar sweep line and for developing therefrom a mapping radar display driving signal and a terrain following radar portion having a profile line memory for storing those sweep line parameters which are collected by the mapping radar portion processor and which coincide with the azimuth angle of a simulated terrain following radar antenna, and a pair of processors for developing therefrom both a terrain following radar display driving signal and an autopilot driving climb/dive signal.
