An emergency oxygen mask, which conventional procedure will cause to be donned at the first sign of smoke, is provided with an eye protecting face plate for viewing a heads up display of flight data critical for safely maneuvering the aircraft. When the oxygen supply is started, the heads up display is activated, for example by the pilot pressing a maximum O2 flow valve. Video data from an interface to the aircraft's ARINC 429 data bus is sent to the heads up display to provide the pilot with aircraft attitude, (pitch and bank), altitude, and heading so that the aircraft can be controlled and emergency procedures can be conducted.
