| - | ===== III. Engine Start, Warm Up And Braking ===== | ||
| - | ====1. Engine Start==== | + | Powered by Jumo211D with Constant Speed prop. WEP lever present but deactivated. |
| + | Supercharger operation with nominal height of 1500 m. | ||
| + | Auto Dive Recovery and weapon release. Armament Single rearward facing 7.92mm MG | ||
| + | 2 x 7.92mm Forward Firing MG, Various bomb types | ||
| + | Dive Angle reference lines are scribed on the Right hand canopy pane | ||
| + | The aircraft is equipped with the AFN-2 gauge which is utilised for beacon homing and Lorenz approach system | ||
| - | * Lever for the dive brakes in position "0". | + | ====START==== |
| - | * Lever for the landing flaps-elevator trim in position "0". | + | |
| - | * Check fuel reservoir. | + | |
| - | ====Electrical Start==== | + | * Fuel Cock Open (Fully Up) |
| + | * Rads Closed (Coolant use Push button, Oil use lever) | ||
| + | * Prop pitch Full fine (Forward) | ||
| + | * Start “I” | ||
| - | - Set lever for the propeller pitch (left fuselage side) to "Start". | + | ====AFTER START==== |
| - | - Pull the handle for the shift blower in position "Bodenlader"[ground blower]. | + | |
| - | - Set shut off valve (instrument panel left below) in position "l+r Behälter und Handpumpe". | + | |
| - | - Use the fuel hand pump (Instrument panel right below) and check at pressure gauge. Use only hand pump by shut off valve in top position or in position "r Behälter II und Handpumpe". | + | |
| - | This circuit breaker is only a saveguard for the device, actuation of the rich-lean-shifting occur through the propeller pitch lever. (Only for engines with rich-lean-device.) | + | |
| - | - Set throttle to idle respectively a little forward. | + | |
| - | - **Push** the starter lever (instrument panel left below) circa 10 sec.( at cold weather at most 20 sec.), until starter is winded. | + | |
| - | - **Pull** the starter lever until engine is running. After engine start release the lever immediately. Pumping with the throttle lever is useless. If the engine doesn't start, let the starter rest first for 1-2 minutes before the next start up attempt. | + | |
| - | ====2. Warm Up==== | + | Warm up with Rads Closed till |
| - | * If the engine runs with diluted oil, then long warm up are detrimental to the engine. | + | * 38 C Coolant Temp |
| - | * **Shortest departure times,** that is from the point of starting to braking, are: | + | * 30 C Oil Temp |
| - | | at 0°C | 1,5 min | | + | Modulate Coolant and Oil rads as required. Suggest full open for Ground operations. |
| - | | at -10°C | 2,5 min | | + | |
| - | | at -20°C | 3,5 min | | + | |
| - | * This departure times can be a little bit exceeded, without damaging the engine. | + | ====TAKE OFF==== |
| - | * After start-up let the cold engine run with 600 U/min[RPM] until oil pressure rises. | + | |
| - | * If the oil pressure doesn't raise after 15 seconds, **stop** the engine immediately. | + | |
| - | * When the oil pressure reaches the max permissible value of 7 atü, adjust the throttle lever as high, that this value is held, but not exceeded. | + | |
| - | * Is the highest revolution and manifold pressure reached, then **short braking**, afterwards departure. | + | |
| - | * **The water temperatures** at cold start through oil dilution **don't** need to be observed. | + | |
| - | * **The oil inlet temperature** should preferably not lie above 30°C. | + | |
| - | * Keep the **water cooler flaps** closed as long as possible, until at departure circa 40°C or more are reached. | + | |
| - | * **Checks at warm up** (with and w/o cold start device, by first one mind the times). | + | |
| - | * **a) Landing gear brakes** | + | |
| - | * The aircraft must be hold [in stand] at n = 1600 U/min[RPM]. | + | |
| - | * **b) Landing Flaps** | + | |
| - | *The landing flaps have to be deployed multiple times. | + | |
| - | * **c) Dive Brakes** | + | |
| - | * Set lever slowly in position "Bremsen"[brake]. | + | |
| - | * **d) Aileron** | + | |
| - | * The aileron must be full movable at deployed landing flaps. | + | |
| - | * **e) Propeller** | + | |
| - | *Activate the propeller pitch adjustment at running engine several times. | + | |
