KV-11

KV-11 System Overview

The KV-11 is an aircraft altitude corrector designed as part of the AP-34B automatic flight control system, providing altitude-dependent correction signals for vertical stabilization.

KV-11 Functional Purpose

The unit converts barometric altitude changes into proportional electrical signals used to stabilize vertical flight, maintain commanded altitude, and reduce pilot workload during various flight modes.

KV-11 Aircraft Application

The corrector is used on Mi-8 / Mi-17 helicopter series, including Mi-8T, Mi-8MT, Mi-8AMT, Mi-8MTV-1 and related variants, within autopilot-controlled flight systems.

KV-11 System Integration

The unit operates within the AP-34B autopilot system as part of the vertical stabilization channel, interacting with onboard amplifiers and executive control elements. The product is also known under designations KV11, KV-11, KB-11.
