This black & white educational U.S. Navy Training Film is one of a series made to train lookouts. This one is about using the position angle system when reporting incoming aircraft. Copyright 1944.

Opening: U.S. Navy Training Film - Position Angle (:06-:21). A sailor serving as a sky lookout uses his binoculars to scan for enemy planes. His job is to report incoming aircraft and their incoming bearing position angle so that the ship can be defended. A plane in the sky as seen through binoculars. Diagram with the line of sight and the horizon, the position angle, and zenith pointed out. The sky above you is a half circle divided by degrees. A plane entering that circle is shown (:22-1:40). A lookout uses an alidade, a sighting device or pointer for determining directions or measuring angles (often used in surveying and formerly astronomy). Diagram shows where the angle you should see the plane is. The diagram shows 'not here' versus 'here' as to where the plane should be sighted. 'Too late' also shows how a plane can evade detection and drop its bombs. A sky lookout uses binoculars and speaks to a telephone talker about the bogey's position angle. The telephone talker radios in the information, the other keeps his eyes on the enemy in the sky (1:41-2:49). End credits (2:50-2:58).
