An aircraft crew vision mask (10) is provided which is especially designed to be used during emergency flight conditions where smoke is present in the cockpit. Preferably, the mask (10) includes a transparent lens (14) supported by a peripheral face seal (16), and has a breathable gas mask (18). In order to provide important aircraft flight information to the wearer (12), the mask (10) is equipped with a display device such as a retinal scanning display device (26) having an output (28). The device (26) is operably coupled to an aircraft information input (46) which supplies digital information such as airspeed, attitude, altitude, heading, vertical speed, navigation information, video inputs or flight manual information to the device (26). A smoke condition sensor (48) and manual input control (50) serve to initiate operation of the device (26) with selective on/off and channel select control capability.
