  • Page 26: Loss Of Coolant

    Aircraft Operating Instructions (AOI) CTLS Page: 3-9 Type: Series: 3.9. Loss of coolant A loss of engine coolant does not mean that a forced landing must be carried out immediately. The coolant is used solely to cool the cylinder heads. The cylinders are air-cooled. As coolant temperature is only indirectly indicated via the cylinder head temperature of the hottest cylinder, engine temperature monitoring is still possible even after a total loss of coolant.

  • Page 27: Failure Of Flap Control

    Aircraft Operating Instructions (AOI) CTLS Page: 3-10 Type: Series: 3.11. Failure of flap control The flap motor is activated by a controller which allows the preselection of the desired flap position. The flap position is indicated digitally.

  • Page 39: Take-Off And Climb

    Aircraft Operating Instructions (AOI) CTLS Page: 4-11 Type: Series: 4.8. Take-off and climb The airfoil of the CTLS offers good climb characteristics, even in the cruise-optimized flap position. Normally on short runways, the flaps are set to 15° for take-off. On hard surface runways, however, take-off is more efficient with the flaps set to 0°.
  • Page 40 Aircraft Operating Instructions (AOI) CTLS Page: 4-12 Type: Series: should be brought to mind when taking off from a short runway with obstacles. Wing flap settings may be adjusted once a safe altitude of 50 m (150 ft) has been reached.

  • Page 41: Cruise

    Aircraft Operating Instructions (AOI) CTLS Page: 4-13 Type: Series: 4.9. Cruise Normal cruise is performed with the flaps set at -6°. The airfoil offers the lowest drag in this setting and fuselage airflow is the most favorable. This is immediately apparent when the flaps are adjusted to this setting - the aircraft accelerates markedly.

  • Page 42: Turns

    Aircraft Operating Instructions (AOI) CTLS Page: 4-14 Type: Series: Warning: The tanks in the CTLS have return flow flapper valves on the fuel tank anti-sloshing rib (refer to Chapter 7 Systems description). They prevent fuel from quickly flowing into the outer tank area during side slipping where it could not be fed into the engine.

  • Page 43: Stall

    Aircraft Operating Instructions (AOI) CTLS Page: 4-15 Type: Series: 4.11. Stall Stalling speed for the CTLS with a weight of 600 kg (1320 lbs) is 72 km/h (39 kcas) with the flaps set at 35°, 77 km/h (42 kcas) with the flaps set at 0° and 81 km/h (44 kcas) with flaps set at -6°.
  • Page 44 Aircraft Operating Instructions (AOI) CTLS Page: 4-16 Type: Series: example, hangars are often found at right angles to the touch-down point, causing dangerous leeward turbulence which cannot be avoided.

  • Page 45: Shutting Down The Engine

    Aircraft Operating Instructions (AOI) CTLS Page: 4-17 Type: Series: 4.13. Shutting down the engine Under normal conditions, the engine cools sufficiently during descent and taxiing that it may be shut down by switching off the ignition. All electrical equipment along with the alternator should be switched off before the engine is shut down in order to protect the equipment from damage caused by a voltage spike.

  • Page 46: Performance

    Aircraft Operating Instructions (AOI) CTLS Page: 5-1 Type: Series: 5. PERFORMANCE Performance data is based on an aircraft in good condition and correct settings. Even the smallest adjustments to the controls or the omission of a small piece of fairing can adversely affect aircraft performance.

  • Page 47: Flight Altitude And Density Altitude

    Aircraft Operating Instructions (AOI) CTLS Page: 5-2 Type: Series: 5.2. Flight altitude and density altitude In order to determine exactly the aircraft performance available for a particular flight, the density altitude must be calculated. The CTLS is equipped with a carbureted engine, the performance of which varies according to ambient temperature and pressure.
  • Page 48 Aircraft Operating Instructions (AOI) CTLS Page: 5-3 Type: Series: An example is given in this diagram. Outside air temperature is -10°C (14° F.) and the altimeter shows a (pressure) altitude of 8000ft. Warning: pressure altitude can be obtained with the reference pressure of the altimeter set to standard atmosphere = 1013.25 hPa (=29.92 in Hg) only.

  • Page 49: Significance Of The Wind Component

    Aircraft Operating Instructions (AOI) CTLS Page: 5-4 Type: Series: 5.3. Significance of the wind component Wind directly affects the flight path and thus aircraft performance. Two diagrams are presented below which show the significance of the wind component. 5.3.1. Wind influence on take-off roll and landing To determine whether the aircraft can take-off safely, it is necessary to determine the prevailing crosswind component.
  • Page 50 Aircraft Operating Instructions (AOI) CTLS Page: 5-5 Type: Series: 5.3.2. Wind influence on cruise Wind also has a noticeable influence on the forward progress of the aircraft over ground in cruise. The relevant components can be easily calculated from the graph. Calculation procedures are analogous to those used to determine take-off procedures, the only difference being the possible inclusion of a tailwind component.

  • Page 51: Engine Performance Subject To Altitude

    Aircraft Operating Instructions (AOI) CTLS Page: 5-6 Type: Series: 5.4. Engine performance subject to altitude Engine performance decreases with increasing (density) altitude. The following data may be used to determine available engine performance. Engine Power at Altitude and Power Setting 2 .

  • Page 52: Calculating The Take-Off Distance

    Aircraft Operating Instructions (AOI) CTLS Page: 5-7 Type: Series: 5.5. Calculating the take-off distance Takeoff distances in the following charts have been analyzed for varying conditions and takeoff weights using FAA approved analysis methods. Warning: Important for the usage of these charts is again the correct density altitude.
  • Page 53 Aircraft Operating Instructions (AOI) CTLS Page: 5-8 Type: Series: 5.5.1. Take-off distance charts The take-off roll distance defines the distance between the begin of the take-off roll and the point where the aircraft leaves the ground. This distance is given for short mown grass on a hard and dry level soil, without wind influence.
  • Page 54 Aircraft Operating Instructions (AOI) CTLS Page: 5-9 Type: Series: 5.5.2. Influences to take-off distance Take-off performance for conditions different to the ones named before can be estimated by using the following rules of thumb. Again the basis is an aircraft in good condition and a well trained pilot.

  • Page 55: Calculating Climb Performance

    Aircraft Operating Instructions (AOI) CTLS Page: 5-10 Type: Series: 5.6. Calculating climb performance The aircraft is nearly always operated under different conditions than ISA standard atmosphere.
