Abstract: The invention is a wheel jack having a cradle for a wheel. The cradle has a first surface and a second surface. The second surface is spaced from the first surface to form a wheel space. An actuator moves the first surface relative to the second surface along a horizontal direction to lift or lower the wheel in the cradle.

Abstract: A flap simulator for an aircraft has a support with a handle. A first couple is on the support and is selectively engageable to a flap track for guiding an aircraft flap. A second couple is also on the support and is selectively engageable to a flap actuator for moving the aircraft flap along the flap track. The support may have an adjustment feature that allows a size of the second couple to be changed to accommodate the flap actuator. The support is apart from the aircraft flap.

Abstract: A drill press assembly has a drill chuck mounted to an extendable stand. The drill chuck is inverted to receive a drill bit oriented to drill in an upward direction. The stand extends between a first height and a second height. The second height is higher than the first height relative to ground. An actuator allows the stand to apply an upward drilling force from ground to the drill chuck at any selectable height.
