-=====Aircraft mechanic before and after flight===== +This aircraft equipped with DB601N running C3 100 octane fuel. 
-  +very similar to standard E4 with the following exceptions.
-  - Prepare for flight+
  
-====Starting the engine====+  * ===NO WEP=== 
 +  * AUTO will target 2600RPM with Full throttle selected.
  
-  - Close the canopy (canopy handle in position „Zu“[closed]). Open right window. +====Start====
-  - 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====+  * Fuel Cock On 
 +  * Prop pitch Full fine 12:00 
 +  * Prop Pitch Manual Variable Pitch 
 +  * Start
  
-  - Open water cooler flaps as needed(crank handle right beside the seat); control device for flap adjustment on the wings (sunken rod flaps open) +====Warm up====
-  - 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====+  * Min Oil Temp 40C 
 +  * Min Coolant temp 40C
  
-  - Control repeatedly the ignition through shifting of the ignition switch at different RPM. Check if the engine is running smooth. +====Take ​off====
-  - 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====+  * 1.35ATA 2600ATA
  
-Braking is only needed, if the interval between 2 flights is more than 2 hours. +====Climb====
-**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+  ​* 1.25/2400 
-  ​- Propeller pitch to 12 o'​clock. +  ​* Climb at 250Kmh ​to 600m then 240Kmh to 8000m then 220-200Kmh ​to ceiling 
-  ​Open water cooler. At low oil temperature keep the oil cooler initially closed. +  ​* 5Min Rating 1.35/2600
-  - 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 ​ ^^ +====Landing====
-| 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 |+
  
-  ​- Check ignition again. Max. 50 U/min loss of Revs. +  * Prop Full Fine 12:00
-  - Check if engine runs smooth and steady. +
-  - Take throttle slowly back. +
-**Attention!** If water temperature exceeds 94°C immediately reduce from full throttle to 1100 U/min until water temp falls.+
  
-====Engine shut off====+====Rad Usage====
  
-  ​- Throttle ​to idle+  ​* Use Oil and Coolant Rads as required ​to control Coolant and Oil Temp
-  ​- Let the engine cool down for circa minutes in idle; set ignition for some time to „M2“, then „M1“ and after that to „0“. Water temperature should not be more than 80°C+  ​* Half open (Oil and Coolant)is generally sufficient ​for most operations except at low IAS or around 6000m 
-  ​- Close the fuel shut off valve only when the engine stopped running. +  * At high speed 1/rd Open is generally sufficient
-  - Set ignition to "​0"​.+  ​* Slow speed is the worse situationSustained slow speed high power manoeuvring with < half rads should be avoided.... suggest Full open in this part of the envelope.
  
-=====Pilot=====+====LIMITATIONS====
  
-====I. Preparation for start====+  * Max IAS 750Mkh 
 +  * Max Flap Speed 250Kmh 
 +  * Max Coolant Temp 100C 
 +  * Max Oil Temp 105C
  
-For starting the engine, warm up, braking and engine shut off see aircraft mechanic. 
-  - Close the cabin (cabin handle in position „Zu“[closed]) **Attention!** Block bolts have to connect correctly. Check if: 
-  - Fuel shut off valve is open. 
-  - Water and oil cooler flaps are open. 
-  - Temp and pressure gauges are working. 
-  - Air screw in 12 o'​clock position. 
-  - Green gear lamps glowing (observe also mechanic indication). 
-  - Elevator trimmed in position 0 to +1° (indicator in front of hand wheel). 
-  - At high air humidity and temps below 0°C activate the pitot tube heater at the switch panel(indicator on instrument panel). 
- 
-====II. Taxing==== 
- 
-  - Landing flaps in zero position. 
-  - Control that water temp doesn'​t rise above 94°C. 
-  - For tight turns roll straight ahead with increased throttle, then start the turn with the brake and throttle down. 
- 
-====III. Start==== 
- 
-  * Adjust landing flaps to 20°, wheel left, indication on left landing flap. 
-  * Start. 
-  * Out of the start increase the velocity to best climb (on ground circa 250 km/h) 
-  * Thereby retract landing gear. Landing gear handle in position „Ein“[up]. 
- 
-  Steady indication of the landing gear through mechanical Indicator.  ​ 
-  Indication of the end position through electrical indicator:  ​ 
-  red = complete retracted  ​ 
-  green = complete extracted 
- 
-  * Retract the landing flaps. Trim the A/C! (indicator on left landing flap) Both hand wheels can be turned at the same time. 
-

-^ Height in km |  0-10  | 
-^ °C |  100  | 
- 
-^ Fuel pressure: | min. 1,1 atü | max 1,5 atü | 
- 
-  * Fuel metering in flight 
- 
-Indicator at the instrument board. Faultless indication only in horizontal position. Switch for metering unit on the right panel. After light up of the rest fuel indicator on the instrument panel only fuel for 10 min. travel flight are left. 
- 
-  * cooler flaps adjustment 
-At normal ambient temperature water cooler half closed. At decreasing of the specified temperature close the flaps accordingly. After flap adjustment additional trimming is required. 
- 
-**Note:** The aircraft velocity depends on the flap adjustment. To reach max. velocity open flaps as far as temps doesn'​t excess max. values. 
- 
-====V. Landing==== 
- 
-  * Reduce speed to 220 km/h. 
-  * Propeller pitch to 12 o'​clock. 
-  * Extract landing gear: gear lever in position „Aus“[down]. After extraction the gear lever to position „Ruhe“[neutral]. 
- 
-  Steady indication through mechanical indicator. 
-  Indication of end position through electrical indicator.  ​ 
-  Red = complete retracted  ​ 
-  Green = complete extracted  ​ 
-  
-  * Extract the landing flaps complete (40°). Trim! Both hand wheels can be turned at the same time. 
- 
-**Attention!** Adhere the velocity limit of 250 km/h by engaged landing flaps. 
-  * Float in with circa 150 km/h indication. The aircraft is pitched strong nose down, glide angle is steep. The A/C loses in less steep angle, as an example to pull out or throttle reduction, rapidly on velocity. 
- 
-====VI. Flight under special conditions==== 
- 
-  * Dive 
-    * Adjust elevator trim, that the A/C can only be hold in a dive through light pushing. This condition is achieved at best by trimming from travel condition 1/2° to tail heavy. If noticed during the dive, that the stick force in direction push reduces, than break up the dive at once. 
-    * Throttle in idle position. 
-    * Adhere, that oil- and water temperature doesn'​t sink below 40°C. Close the water cooler half to complete dependent on weather conditions. 
-    * Propeller pitch circa 9:30 o'​clock. 
-**Attention!** Max. allowed engine revs for dive 3000 U/min[RPM]. 
- 
-  * Flight at night 
-Activate cockpit light. Especially check the elevator trim before the start. 
- 
-====VII. Emergencies==== 
- 
-  * Touch and go 
-Touch and go with full deflected landing flaps. After touch and go retract flaps slowly in adequate height above the ground and trim the aircraft. 
- 
-**Attention!** Consider even by touch and go the speed limit of 250 km/h at deflected flaps. 
- 
-  * Landing gear emergency extraction with defect oil pressure device. 
-    - Landing gear in position „Aus“[down]. 
-    - Pull the emergency lever. 
-    - If the landing gear isn't locked (end position recognizably through green lights at the landing gear indicator) locking can be achieved through banking. 
- 
-  * Emergency landing through engine fault 
-    * At low height pull up immediately,​ until V-200 km/h is attained. 
-    * Deflect landing flaps full, trim tail heavy. 
-    * Extract the landing gear through the emergency extraction. 
-**Attention!** At bad area an emergency landing is saver with retracted landing gear. At high altitude it is practicable,​ to achieve a bigger distance, to begin with landing gear and flaps extraction at a height below 1000 m. 
-    * Propeller pitch to 9:30 o'​clock. 
-    * Switch off ignition "​0"​. 
-    * Fuel shut of valve in position „Zu“[closed]. 
- 
-  * Bail out 
-    - Reduce speed if possible. 
-    - Switch off ignition "​0",​ close fuel-shut-off valve in position „Zu“[closed]. 
-    - Pull red marked cabin lever at the left side of the fuselage. (cabin will be entrained through the air stream) 
-    - Unstrap and leave the A/C.
