Product Description
The 550-684 is a vertical speed indicator (VSI) that displays aircraft climb and descent rates on the flight deck. This mechanical instrument uses precision capsules connected to the static pressure system to measure altitude change in feet per minute. Pilots reference the VSI during climbs, descents, and approaches to maintain controlled vertical flight.
The instrument mounts in standard panel cutouts and connects via static line to the aircraft's pressure system. Installation and calibration must follow the aircraft maintenance manual and FAA-approved procedures to ensure accurate airspeed readings.
