Original U.S. WWII USAAF Fairchild A-10A Sextant - 1942
Original Item: Only One Available. WWII US Army Air Force A10 Aircraft Sextant -
A sextant is an instrument used to measure the angle between any two visible objects. Its primary use is to determine the angle between a celestial object and the horizon which is known as the altitude. Making this measurement is known as sighting the object, shooting the object, or taking a sight. The angle, and the time when it was measured, can be used to calculate a position line on a nautical or aeronautical chart. A common use of the sextant is to sight the sun at noon to find one's latitude. Since the sextant can be used to measure the angle between any two objects, it can be held horizontally to measure the angle between any two landmarks which will allow for calculation of a position on a chart. A sextant can also be used to measure the Lunar distance between the moon and another celestial object (e.g., star, planet) in order to determine Greenwich time.
This WWII Fairchild USAAF A-10A Sextant was issued during World War two to personnel from the Army Air Force (AAF). Complete with the issue wooden box, which has multiple compartments to house the different components of the apparatus and offered in excellent condition.
