Winter Instruments Altimeters

General Description

Winter Instruments Altimeter - Developed especially for gliding, the 4 FGH 40 (4030 – 4555) altimeter shows absolute altitude and relevant flight level within a range of 0 – 20,000′ or 0 – 10,000 m. The instrument works by measuring the static air pressure using an elastic diaphragm cell (aneroid cell). A rotary knob is provided for the Millibar or HG setting.

Altimeters measure static air pressure, which decreases with altitude. The pressure-sensitive measuring element is a diaphragm capsule from which the air has been removed (aneroid capsule), which reacts to the effect of changing air pressure as the aircraft changes altitude. Tempered, aged copper-beryllium diaphragms ensure highly accurate readings. Diaphragm movement is transmitted to the instrument pointers by a linkage and gearwheels – the whole is insensitive to shock and vibration. A bimetal link compensates for the effects of temperature change.

The most popular Winter Altimeter in the USA is the 57 mm 4 FGH 40 Item # 4555. 

Wing & Wheels stocks the altimeters highlighted in yellow in the table. Other Altimeters please allow approximately four weeks Winter production time.

Features
