Blenheim IV cockpit

Engine Boost. Shows your throttle setting for both engines. If either engine takes damage you will see the effects here.
Clock. Measures game time, not your local time.
Magnetic compass. This one is rather tricky to read. Use the slave compass instead (11).
Engine oil temperature. One gauge per engine.
Engine oil pressure. One gauge per engine. If you are leaking oil, pressure drops and temperature increases (gauge 4).
RPM. Shows the revolutions of your propeller in units of hundreds per minute, e.g. 20 = 2000 RPM. See the effects on this gauge by changing from Economy to Continuous and Maximum RPM with ‘ key.
Indicated Airspeed. Readout is in tens of MPH, e.g. 14=140 MPH. The inner scale shows speeds over 340 MPH.
Artificial Horizon. Shows the position of your wingline relative to the horizon.
Vertical Speed Indicator (VsI). Shows whether you are climbing or sinking in thousands of feet/min.
Altimeter. Readout is in hundreds (long arm) and thousands of feet (short arm). This Blenheim is currently at 320 feet Above Sea Level (ASL).
Slave compass. Add a 0 to the readout to determine your compass heading, e.g. 9 = 90 degrees (east), 27 = 270 degrees (west).
Inclinometer. Shows your Turn and Bank and your Yaw (when you skid by applying rudder).
Landing Gear Indicator. Arm down means wheels are down, arm up means wheels are… yeah, up.

Fuel gauges. Not shown in this picture – look right and behind you to watch fuel levels.

Nice and roomy! Manipulate your controls and see the levers move.
