Review UMA Aviation Aircraft Altimeter 1/8 Non Tso

The UMA 5-300-20 aircraft altimeter, manufactured by U-S Tech, is a reliable and accurate avionic instrument designed to measure and display the altitude of an aircraft above mean sea level. This altimeter is certified to meet the requirements of TSO-C11a, which is a technical standard order set by the Federal Aviation Administration (FAA).

The UMA 5-300-20 altimeter is a 1/8 inch barometric instrument, which means that the barometric pressure setting is made by adjusting the dial in eighths of an inch. The instrument is designed to operate in a wide temperature range, from -65 F to 150 F, making it suitable for use in various flying conditions.

The altimeter features a clear, easy-to-read dial with white markings on a black background. The dial is divided into two parts - the outer part shows the altitude in thousands of feet, while the inner part displays the altitude in hundreds and tens of feet. The altimeter also has a red pointer that moves across the dial to indicate the current altitude.

The UMA 5-300-20 altimeter is equipped with a fail-safe mechanism that activates a warning flag and horn when the altitude approaches a pre-set value. This feature is essential for ensuring the safety of the aircraft and its occupants by alerting the pilot to potential hazards, such as entering a cloud layer or approaching minimum safe altitude.

The altimeter housing is made of rugged and durable aluminum, making it resistant to vibration and shock. The instrument is also designed to be easy to install, with a standard 1.25 inch mounting hole and clear mounting instructions provided.

In summary, the UMA 5-300-20 aircraft altimeter is a high-performance and reliable avionic instrument that meets the stringent requirements of TSO-C11a certification. It is designed to provide accurate altitude readings in a wide range of temperatures and flying conditions, with a clear and easy-to-read dial and essential safety features such as a fail-safe mechanism.
