These static air pressure sensing instruments were made for Elliott Bros by Munro to carry out gain switching for the autostabilisers on the early Lightning as a function of altitude. They were incorporated in the Mk13 Computer Unit.
They also incorporated an Elliott AC pick-off to give the height lock signal for ILS conflict approach.
