- | =====Aircraft mechanic before and after flight===== | + | ====Start==== |
- | + | ||
- | - Prepare for flight | + | |
- | ====Starting the engine==== | + | * Fuel Cock On |
+ | * Prop pitch Full fine 12:00 | ||
+ | * Prop Pitch Manual Variable Pitch | ||
+ | * Start | ||
- | - Close the canopy (canopy handle in position „Zu“[closed]). Open right window. | + | ====Warm up==== |
- | - Gear lever in position „Ruhe“[neutral]. | + | |
- | - Fuel shut off valve lever in position „Auf“[open]. | + | |
- | - Throttle to idle. | + | |
- | - Let the starter be charged (Press [B]I[/B] to start the engine). | + | |
- | - Inject with the injector pump 2 or 3 times at charging(at cold weather 4 or 5 times). By hot engine only 1 or 2 injections. | + | |
- | - Control oil pressure: by cold engine within the first 3 to 5 seconds the pressure must have risen to 6 to 8 atü; if not stop the engine immediately. | + | |
- | - If engine doesn't start: before the restart wait some minutes, then repeat the procedure. | + | |
- | ====Warm up of the engine==== | + | * Min Oil Temp 40C |
+ | * Min Coolant temp 40C | ||
- | - Open water cooler flaps as needed(crank handle right beside the seat); control device for flap adjustment on the wings (sunken rod = flaps open) | + | ====Take off==== |
- | - At colt weather close the oil cooler (lever left beside the seat). | + | |
- | - After engine start slowly increase the RPM by beginning fall of oil pressure to max. 1000 RPM. Keep here the oil pressure between 5 and 6 atü. | + | |
- | ====Checks during warm up==== | + | * 1.3ATA 2400ATA |
+ | * WEP 1.45 2400ATA (1 Min Clockwork timer) | ||
- | - Control repeatedly the ignition through shifting of the ignition switch at different RPM. Check if the engine is running smooth. | + | ====Climb==== |
- | - At circa 1400 RPM control the fuel pump: switch the fuel shut off valve for an half minute to „P2“ and „P1“ and check the fuel pressure for intense unsteadiness or rough running engine. | + | |
- | ====Braking the engine==== | + | * 1.2/2300 |
+ | * Climb at 250Kmh to 600m then 240Kmh to 8000m then 220-200Kmh to ceiling | ||
+ | * 5Min Rating 1.3/2400 | ||
- | Braking is only needed, if the interval between 2 flights is more than 2 hours. | + | ====Landing==== |
- | **Attention!** Trim full tail heavy. Position the A/C exact opposite to the wind. If possible strain the tail. | + | |
- | - Check if the cabin is closed. | + | * Prop Full Fine 12:00 |
- | - Propeller pitch to 12 o'clock. | + | |
- | - Open water cooler. At low oil temperature keep the oil cooler initially closed. | + | |
- | - Only braking at min. 30°C oil entry temp (push button on gauge) and max. 80°C water temp at beginning of braking. | + | |
- | - Pull the Stick and hold it. | + | |
- | - Push the throttle steady to full throttle. | + | |
- | - At full throttle check gauges. | + | |
- | ^ Values at braking ^^ | + | ====Rad Usage==== |
- | | Revs (at 12 o'clock) | 2200 to 2250 U/min[RPM] | | + | |
- | | pressure | 1,35 ata | | + | |
- | | oil pressure | 2,5 to 5 atü (normal 3,5) | | + | |
- | | water temperature | max. 94°C | | + | |
- | | oil entry temperature | min. 30°C | | + | |
- | | fuel pressure | 1,0 to 1,5 atü | | + | |
