Hi all,
we use NVG (Anvis5) as well, me having 760 + hrs so far with them.
Some of our older pilots, who donīt use them frequently, seem to get problems with their neck quicker even with less total NVG hours logged.
I myself had problems with pain in the elbow, which went away after treatment of the neck (some nervs just didnīt like the tension of my muskels there)
It helps to straighten up the neck frequently.
Including sitting straight in the bird, whenever you can.
Also, get with you back so close to a wall, that you nearly fall forward and get your back and head on to the wall, lifting your arms horizontal and your forearms vertical and holding that position for half a minute or so. Even if it looks funny to bystanders, do that a couple of times a day.
It helps to reduce the problems you might encounter flying NVG.
Greetings Udo
