Corresponding look at the right side of the instrument panel reveals a set of engine instruments. The largest one at the top is the engine RPM counter, also known as the tachometer. The red-coloured one is boost pressure gauge, accompanied by the warning lamp for fuel pressure to its left. In the lower row, left-to-right are the yellow oil pressure gauge, orange oil temperature gauge and the green radiator temperature gauge. The lowest instrument in this view is the fuel gauge providing information about number of gallons left in the bottom main tank. The gauge did not provide continuous information, to activate the readout the pilot had to press a small button visible to the left of the instrument display.
