This is the original, developed by Hendricks Sewing Company and tested to 9 ½ G’s in an F-15 Eagle at Eglin AFB. This kneeboard has also survived ejections and stayed with the pilot on the way down. Very compact design for tight cockpits, made of Cordura with ABS clipboard and is the only kneeboard of this type approved by NAVAIR for carrier operations. Has checklist ring holders in both spines and adjustable elastic legstrap with nylon, anti-FOD side release buckle. Kneeboard is the size of a 5” x 8” mini-legal pad with stabilizers on both sides of the leg. It features a clear strap to hold approach plates. This is the kneeboard the military has relied on for over 20 years.
