Statoscope

 

a device for recording the change in altitude of an aircraft according to the measured difference between the atmospheric pressure and the pressure within the device. Stato-scopes are designed primarily for aerial surveying in the production of maps. The most widely used type is in the form of a liquid differential-pressure barometer consisting of two identical, automatically shifting manometric systems connected as communicating vessels. The barometric altitudes at which photographs are taken as well as changes in altitude are calculated relative to the observed difference in the levels of alcohol in the manometric tubes and the pressure and temperature at the flight altitude. The accuracy achieved is of the order of 0.5–1.0 m.

For aerial photography, aircraft were fitted with gyrostabilizers (to ensure the stability), and readings of radio altimeter and statoscope were registered.
