Japanese Patent JPS5010675
Kind Code:
A
Abstract:
An airport altimeter setting indicator system includes a barometric pressure sensor that provides a signal in accordance with the local barometric pressure at the airport. The local barometric pressure signal is converted to a corresponding local pressure altitude signal in accordance with standard day conditions. A signal proportional to airport elevation is subtracted from the pressure altitude signal providing an altitude difference signal. The altitude difference signal is converted to a corresponding barometric pressure signal under standard day conditions to provide the desired altimeter setting pressure.
