About this Photo
Description:
With radial engines, it is vital to check for the absence of 'hydraulic lock', which can happen when oil accumulates in the lower cylinders while the aircraft sits idle over time. Here, Craig Morrison is 'pulling through' the Nanchang's engine to check. The procedure also assists with priming the engine for start.
