The left side of the instrument panel is occupied by the following switches and instruments. In the topmost corner are the navigation light switch and flap selector, here in the "up" position. The twin instruments immediately below are oxygen supply indicators. Still lower and positioned somewhat randomly there is the rectangular landing gear indicator with UP / DOWN lights. To the left of it there is the clock, one of the many different clock types to be found on Spitfires. The two flip switches in the lower left corner control the magneto ignition. The lowest instrument in this view is the brake pressure gauge. The last instrument, slightly above and to the right is the elevator trim tab indicator.
