Rate of Climb Indicator

A Rate of Climb Indicator manufactured by The Bendix Corporation in October 1967.

Concorde Equipment Code: 66-071-087-00

Commonly known as a Vertical Speed Indicator (VSI) or Bendix Pioneer Gauge, this measured changes in static air pressure to show how fast the Concorde was climbing or descending. The indicator was connected to a static port to sense outside air pressure. Inside there is a flexible diaphragm connects directly to the pressure source giving an accurate reading.

This specific indicator was fitted to a prototype aircraft (likely 002). The final two photos display legendary chief test pilots Brian Trubshaw and André Turcat, alongside this exact indicator configuration in place on the main instrument panel of 002. Because the cockpits of prototypes 001 and 002 underwent extensive modifications to facilitate ongoing supersonic flight testing, this indicator layout was later removed to make way for weather radar equipment. As a result, neither museum-preserved prototype retains this exact gauge configuration today.

The dial is flawless with no cracks, scratches or discolouring. The casing bears its original aluminum Bendix identification tag alongside various vintage stamps tracking its overhaul and flight certification. Its unique Concorde Equipment Code has been hand painted in red and white highlighting this exact gauge was for early development engineering. The indicator was released by BAC at the closure of the test programme along with an assortment of other test-era spares.

Overall, a front-panel instrument from the historic dawn of supersonic passenger flight. At 59 years of age, it is an exceptionally well-preserved piece of Concorde history that will serve as a great centerpiece for any serious aviation collection.
