Provided is an emergency warning device useful for quickly warning persons in danger of being struck by a disabled aircraft during an emergency landing procedure. The emergency warning device consists of a mounting assembly, a sound emitting device, a power supply, and a switch. The mounting assembly consists of a door pivotably mounted on the cowling of the aircraft, the door having an external surface substantially flush with the external surface of the aircraft such that the aerodynamic characteristics of the aircraft are not substantially altered when the door is in a closed position. The power source selectively provides power, independent from the aircraft power, to the sound emitting device. The switch connects the sound emitting device to the power source upon activation of the emergency warning device. The mounting assembly exposes the sound emitting device in an open position upon activation of the emergency warning device such that the sound emitting device is audible external to the aircraft. A portable version of the emergency warning device is also provided, which is self-contained in a unitary housing. An inverted U-shaped member is provided to allow the self-contained emergency warning device to be easily and quickly mounted on the outside of an open cockpit window in the case of an emergency.
