Pull Up Master Caution Warning Button / Indicator by KORRY.

Pull up Master Caution Indicator button by KORRY.

Part of GPWS, the item will sound and light to direct crew to pull up to avoid terrain. It can be de-activated by pressing.

The button/illumination has not been tested, but is in 'as removed' condition and therefore the item should function as intended.

The part was used within the glareshield of various classic aircraft, prior to the introduction of automated and computerised systems.
