Abstract

An aircraft pilot kneeboard is provided including a bottom member having an inner compartment. A top member is connected to the bottom member by a first axle. Flanges extend outwardly from the bottom member. Straps are attached to the flanges. Springs are located in the flanges for holding writing instruments. The springs have turns distanced less than a diameter of the writing instruments. Clamps are located at lower and upper edges of the top member. A tiltable surface is connected to an upper surface of the second clamp by a second axle. The second axle extends widthwise across the kneeboard. The kneeboard further includes a light emitting diode for lighting a top surface of the top member. The kneeboard further includes an interactive screen attached to the tiltable surface for providing a military moving map and a brownout/obscured landing system.
