A flight helmet, sometimes nicknamed a "bone dome", is a special type of helmet primarily worn by military aircrew.
A flight helmet can provide:
 |
| A visor to shield the eyes from sunlight, flash and laser beams. |
 |
| Noise attenuation, headphones and a microphone (except when included in a mask). |
 |
| Impact protection to reduce the risk of head injury (e.g. in the event of a parachute landing) and protection from wind blast (e.g. in the event of ejection). |
 |
The design of a flight helmet may also consider:
Comfort - including the weight, centre of gravity and provision for cooling and ventilation.
|
 |
| Compatibility with an oxygen mask (for high altitude flight and NBC protection). |
