HMD & Neck Injuries:---

[khansaheeb]

Radar with side antennas is ergonomically better than Helmet mounted system. Not only in ejection but also in looking for targets consistently in case of engagement as well as with the neck movement more than desired.

Solution is simple : have an inverse force pressure bag to counter the force on the neck during ejection.

Hi,

Seems like the helmets equipped with HMD's are not a safe bet for pilots with not so strong neck muscles---.

Helmets with HMD are heavier than conventional pilot helmets & in case of a deployment of an ejection seat from an aircraft may result in severe injuries to pilot's neck due to the weight of the helmet and resulting forces produced due to accelerated motion.

It could possibly result in the broken neck of the pilot or severe injuries to the neck.

The first article talks about minimum body weight for a pilot wearing HMD.

The other articles are informative as well---.

Looks like that pretty soon we would be seeing pilots with thick strong necks flying the modern aircrafts with HMD's

Sir ji ,,, watch this video carefully. This incident shook the NATO. They were surprise russian ejection seat tech. Rest discuss later.
Ejection 2 second before crash.no injuries.

Yes but ejection was at slow speed and stresses low.

speed is slow , but look at the angle and distance from point of ejection to ground. Which is unbelivable.
