GROUNDSPEED AND TIME-TO-GO COMPUTER

摘要

A groundspeed and time-to-go computer for an aircraft. The groundspeed computation is implemented by counting the pulses from a fixed frequency pulse generator during an interval established by the units transmitter of distance-measuring equipment (DME), and which interval is inversely proportional to groundspeed. The time-to-go computation is implemented by counting down the count from units, tens and hundreds DME transmitters until zero is reached and noting the interval.
