The U.S. Air Force is introducing a
new neck muscle exercise machine in air force gyms frequented by fighter
pilots. This is because the new helmets (the JHMCS, or Joint Helmet Mounted
Cueing System) weighs 4.3 pounds, which is about fifty percent more than a
plain old helmet. That extra weight may not seem like much, but when making a
tight turn, the gravitational pull (or "Gs") makes the helmet feel like it
weighs 38 pounds. You need strong neck muscles to deal with that. For decades
now, fighter pilots have had to spend a lot of time building upper body
strength in the gym, in order to be able to handle the G forces. Otherwise,
pilots can get groggy, or even pass out in flight, as well as land with
strained muscles. All this gym time is one reason fighter pilots are such chick
magnets. It's unknown if the thick necks, required to handle the JHMCS,will change this.
The JHMCS allows a pilot to see displayed on his
visor, critical flight and navigation information. Sort of like a see-through
computer monitor or Head Up Display. Most importantly, the pilot can turn their
head towards a target, get an enemy aircraft into the crosshairs displayed on
the visor, and fire a missile that will promptly go after target the pilot was
looking at. There is an additional advantage in letting the pilot look around
more often without having to look down at cockpit displays, or straight ahead
at a HUD (Head Up Display.) This kind of freedom gives an experienced pilot an
extra edge in finding enemy aircraft or targets, and maneuvering to get into a
better position for attacks. JHMCS is also useful for air to ground attacks.
