LESSONS FOR THE BOMB AIMER No.3 [Main Title]

Technical instructional film for bomb aimers, focusing on how to measure the direction and speed of the wind by use of timing bead and wind gauge bar.

Addresses the effect of drift on bombing and calculating angles of drift using course setting bomb sight. Examples of different methods of usage: “Set terminal velocity to infinity and enemy speed to zero”, “Set maximum wind speed and computed air speed”, “Set height slider to computed height on the red scale”, “Level the sight”, “On any course adjust for drift”. Effect of trail when bombing should be taken into account. If aircraft moves into a layer of air with a different wind direction then a new calculation will be required.
