Abstract

549,941. Measuring angles. KRONFELD, R. Sept. 6, 1941, No. 11396. [Class 97 (ii)] [Also in Group XXXIII] To teach an aircraft pilot to maintain his aircraft at a predetermined attitude to the horizontal or to another aircraft or to a marker on a towing rope, a pair of horizontally spaced sights 11, 13 is mounted so as to be vertically adjustable upon a column 4 to suit the normal line of sight of the pilot. The device may be used in a ground trainer or in a towed glider. The sights 11, 13 are mounted on rods 9, 10 connected to a friction plate 5a angularly adjustable with respect to a plate 5 on a bracket capable of being clamped to the column 4 by a screw 6, the column having graduations co-operating with a pointer 7 on the bracket to enable it to be readily reset to any position. The sight 11 may have end markers 12 and the sight 13 may support additional adjustable bars 16, 17 to mark permissible deviations from the normal direction. The bracket carries an air speed indicator 20, and a side-slip indicator comprising a pivoted wind vane 21.
