Abstract
The device comprises a means for measuring a dynamic temperature on the outside of the aircraft, a means for determining a static temperature around the aircraft, using said dynamic temperature, a means for determining, using said static temperature and a thermodynamic equation, a second temperature value corresponding to an estimated temperature at said destination altitude, a means for determining the difference between said first and second temperature values, and a means for emitting a warning signal when said difference is greater than a predetermined value.
