notes: label: Description
content: This instrument is in a metal case painted black. It is designed to carry out several calculations needed by pilots. One scale allows one to set the magnetic variation and the true track and read off the magnetic heading. Other scales allow one to set the true speed, and the direction and velocity of the wind and read off the ground speed. Scales on and around a disc attached to the inside of the case allow one to correct readings of air speed and of altitude for temperature and to perform other calculations relating to distance and to fuel.
