Start Up Before you go flying, you'll need to learn how to start the engines. This tutorial will take you through starting the Cessna 172p.

In this lesson we'll go through starting the aircraft. 10 The fuel selector is set to BOTH and the carb heat is off. 344.0 -48.7 0.0 -0.2 0.235 0.36 50.0 Make sure fuel mixture is set to fully rich. 346.8 -25.8 0.0 -0.2 0.2 0.4 62.3 -0.3000 0.0800 -0.2050 3.0000 Use the m key or mouse to select fuller mixture. /controls/engines/engine/mixture 0.85 /controls/engines/engine/mixture 0.85 Open the throttle slightly. Use your joystick throttle control, or PgUp to increase throttle to about 10%. 346.8 -25.8 0.0 -0.2 0.2 0.4 62.3 -0.3342 -0.0027 -0.2289 3.1156 Push in the throttle using PgUp, or your joystick throttle control. Open the throttle a bit more. /controls/engines/engine/throttle 0.05 That's a bit too much. Pull it out slightly using your joystick throttle control, or PgDn. That's a bit too much - pull it out slightly. /controls/engines/engine/throttle 0.2 /controls/engines/engine/throttle 0.05 /controls/engines/engine/throttle 0.2 Prime the engine for start. You'll have to pull the primer lever all the way towards you and then push it in, several times. 12.2 -35.2 0.0 -0.2 0.3 0.4 35.0 -0.3000 -0.4258 -0.2417 2.6500 Pull and push the primer lever /controls/engines/engine/primer 3 /controls/engines/engine/primer 2 Now, we'll check no-one is about to walk into our propeller. 2 44.0 -15.7 0.0 -0.2 0.3 0.4 55.0 Looks clear. 2 296.6 -10.4 0.0 -0.2 0.3 0.4 55.0 Turn the master switch on. 12.2 -35.2 0.0 -0.2 0.3 0.4 35.0 -0.3000 -0.3858 -0.1917 1.9333 /sim/model/hide-yoke true Click the battery master switch to turn it on. /controls/engines/engine/master-bat 0 /controls/engines/engine/master-bat 1 We need to switch on the magnetos. Click the middle hotspot three times, or use your mouse scroll wheel, so the key is set to BOTH. 12.2 -35.2 0.0 -0.2 0.3 0.4 35.0 -0.3689 -0.3663 -0.2985 3.0000 Click the middle hotspot three times, so both magnetos are on and the key is set to BOTH. /controls/engines/engine/magnetos 3 /controls/engines/engine/magnetos 3 Finally, we can start the engine. Hold down s, or the right hotspot until the engine catches. 12.2 -35.2 0.0 -0.2 0.3 0.4 35.0 -0.3689 -0.3663 -0.2985 3.0000 Wrong way - set the magnetos back to BOTH. You need the magnetos on to start the engine. Set them to BOTH by clicking the middle hotspot or pressing ]. /controls/engines/engine/magnetos 3 /engines/engine/running 1 Great, the engine is running. Adjust the throttle so we're running at between 800 and 1000 RPM. 360.0 -23.0 0.0 -0.2 0.2 0.4 60.0 -0.3791 -0.3089 -0.1320 3.8622 /sim/panel-hotspots false You can release the starter motor now - the engine is running /controls/engines/engine/starter true That's a bit high. Reduce throttle to below 1000 RPM using PgDn, or your joystick throttle control. /engines/engine/rpm 1000.0 That's too low. Increase throttle to above 800 RPM with PgUp, or your joystick throttle control. /engines/engine/rpm 800.0 /engines/engine/rpm 800 /engines/engine/rpm 1000 Now turn the master alternator switch on. 12.2 -35.2 0.0 -0.2 0.3 0.4 35.0 -0.3375 -0.4142 -0.2242 1.6333 /sim/model/hide-yoke true Click the alternator master switch to turn it on. /controls/engines/engine/master-alt 0 /controls/engines/engine/master-alt 1 Finally, switch on the master avionics. 12.2 -35.2 0.0 -0.2 0.3 0.4 35.0 -0.3500 -0.3233 -0.2583 1.6333 Flip the master avionics switch. /controls/switches/master-avionics 0 /controls/switches/master-avionics 1 Great, our lesson is complete. We're now ready to taxi to the runway. /sim/model/hide-yoke false 360.0 -10.0 0.0 -0.2 0.2 0.4 60.0
