(5) Oil pressure gauge for each engine using pressure system. (6) Temperature gauge for each liquid-cooled engine. (7) Oil temperature gauge for each air-cooled engine. (8) Manifold pressure gauge for each altitude engine. (9) Fuel gauge indicating the quantity of fuel in each tank. (10) Landing gear position indicator, if the aircraft has a retractable landing gear.
