Instinctive Cut Off Switch
« on: January 15, 2015, 10:28:50 PM »
Been wondering what this switch is and found it in the 'Instruments and Controls' documentation but I have no idea what it does.
It's called the Instinctive Cut Off Switch (on pilots column).

What does it do? sounds like a 'Dead Mans Handle' sort of function but you can't put the brakes on at 50,000ft!!!!!

Zap - straight to AP112C-0800-1A - Autopilot Mk 10A - This is the cut out switch for the Autopilot system the should be one on the P2 stick as well

"6.   The autopilot can be disengaged at any time by pressing either of the pilot’s
instinctive cut-out buttons. These form part of the aircraft cut-out circuits and break
the supply to the ENGAGE switch, causing the channel relays to de-energize."

This is the same on aircraft fitted with Mk 10B

Terrific, thanks again Deeleyt, I know I can always rely on excellent advice and answers on this forum.
Another question I can answer when people ask. In this case it was during a primary school trip, they were 10/11 year old and came up with some great questions, 99% I could answer, this was the 1% I couldn't!
Cheers
Dave
