Which one of the following is not an essential factor in integrating the HMD with the helmet?

A)

Geometry of the cockpit

B)

Overall minimum weight for comfort

C)

Must not interfere with the oxygen mask

D)

Protect eyes and head during high-speed ejection

Correct Answer : Geometry of the cockpit

Explanation : The geometry of the cockpit does not affect the HMD nor the helmet as the helmet is worn by the pilot and the FOV of the HMD moves with the pilot’s head. Some of the factors that are essential are the minimum weight for comfort while wearing the helmet for long flight hours and in high g maneuvers, crashworthiness of the helmet with HMD and communication systems integrated no interference with other objects in the cockpit such as oxygen mask as it is crucial at ejection at high speeds.
