Abstract
An airspeed indicator with quantitative voice output converts an electrical or pressure value to an indicated airspeed value and provides the numerical airspeed value to the pilot vocally. The device uses a precision pressure transducer to convert pitot tube pressure to an equivalent electrical signal, which is used to operate an indicator on the instrument panel and to operate a voice synthesizer to announce the current airspeed value to the pilot, either through a speaker in the aircraft cabin, in the pilot'"'"'s headset or in the device itself. The vocal output from the airspeed indicator can be enabled or disabled, according to the pilot'"'"'s needs. The frequency with which the device provides updated airspeed values to the pilot can be adjusted to suit the pilot'"'"'s preference.
