Review KOLLSMAN Used Aircraft Altimeter Mph Pn# Piper Cub Aeronca fits 230

The Kollsman 657K-07-3758 is a high-performance aircraft altimeter specifically designed for use in general aviation aircraft, such as the Piper Cub and Aeronca models. This altimeter is a key instrument in ensuring safe and efficient flight by providing accurate and reliable altitude readings to the pilot.

The 657K-07-3758 altimeter is a mechanical barometric instrument, featuring a large, easy-to-read dial with white digits on a black background for enhanced visibility. The dial is graduated in feet and inches, allowing precise altitude readings up to an impressive 30,000 feet. The altimeter housing is made of durable aluminum, making it lightweight and resilient to the harsh conditions of flight.

One of the standout features of the Kollsman 657K-07-3758 altimeter is its ability to compensate for airspeed up to 230 mph. This feature, known as a "PIM" or "pressure-compensated, integrated, mechanical" system, allows the altimeter to provide accurate altitude readings even in high-speed flight conditions. This is particularly important for pilots of faster aircraft or those flying at higher altitudes, where pressure changes can significantly affect altitude readings.

The Kollsman 657K-07-3758 altimeter also includes a built-in manually-set adjustment for correction of barometric pressure differences between different airfields or locations. This feature allows pilots to easily set the altimeter to the local barometric pressure at their departure or arrival airfield, ensuring consistent and accurate altitude readings throughout their flight.

In terms of installation, the 657K-07-3758 altimeter is compatible with standard 1-inch diameter instrument panels commonly found in general aviation aircraft. It comes with all necessary mounting hardware, making installation a straightforward process for most pilots or aircraft maintenance personnel.

In summary, the Kollsman 657K-07-3758 is a high-precision, high-performance altimeter designed for use in general aviation aircraft. Its ability to compensate for airspeed up to 230 mph, large, easy-to-read dial, and built-in barometric pressure correction make it an essential instrument for any pilot seeking accurate and reliable altitude information during their flights.
