4.11 Engine Shut-down and Restart in flight : SHUT-DOWN 1. Throttle -------------------------------- Close to IDLE (for 2 minutes) 2. All electrical equipment not needed ----- OFF 3. Ignition -------------------------------- OFF 4. Propeller control ----------------------- PULL - TURN LEFT The propeller is now feathered and the wind-milling effect on the engine will cease. RESTART 1. Choke (with cold engine) -------------- PULL 2. Ignition -------------------------------- ON 3. Propeller Control ----------------------- TURN TO START POSITION The wind-milling effect should cause the engine to start. Should the speed not produce the wind-milling use the starter to effect RPM. 4. Throttle -------------------------------- IDLE (until oil temperature indicates 500 C) . To return to cruise flight the propeller control must be again set as in Par. 4.l0. 4.12 Soaring: When updrafts are encountered reduce power to idle. If positive vertical velocity, shut off engine as in Par. 4.11 Circle climb while maintaining a speed of 90— 95 km/h (56 — 6o mph). To. return to powered flight refer to Par. 4.11. 4—9

33 Hoffmann 4 H 36 DIMONA Normal Procedures 4.14 Decent and Approach : Decent with power as required to obtain 180 km/h (112 mph). When entering pattern the propeller should be switched to START position. When turning base leg reduce power to bring the RPM under 1500 RPM. On final electric Boost Pump - ON, Airspeed — 95 km ( 60 mph), Yellow Triangle. 4.15 Landing: Airspeed - Reduce Airbrakes - as required Throttle - Closed Touchdown - Back pressure on stick to produce 3 point attitude CAUTION Do not apply full airbrake at touchdown. The coupling with the brake system will result in landing with blocked wheels! 4.16 Engine Shut-Down : Parking Brake ----------------------- As required Throttle ------------------------------- Closed (idle engine for 2 minutes for cooling) Radios and NAV. Equipment ----- Off Electrical Switches ----------------- Off Ignition ------------------------------ Off Master switch ----------------------- Off CAUTION If, due to taxiing the brakes have been used excessively, over-heating may result. Do not set the parking brakes until the brakes have cooled. 4-11

33.1 Hoffmann 4 H 36 DIMONA Slip 4.17 Slip : 4.17.1 Entry and Recovery : Slip is practicable from 80 km/h (43 kt) (50 mph) to 120 km/h (65 kt) (75 mph). Throttle idle Apply aileron control in direction of intended slip. Apply opposite rudder simultaneous. To maintain desired airspeed apply aft stick. Use airbrakes additionally if required. Recover: Reset controls in neutral position. 4.17.2 Characteristics: Yaw up to 35* and bank up to 10* are practicable with full rudder and suitable aileron control. High yaw angels require extensive elevator deflections up to the rear stop of the stick. NOTE Stall is not possible in the slip. At rear C.G. positions, nose pitches down slowly. Speed after recovery is not less than 80 km/h (43 kt) (50 mph). Rates of descent from 3 m/s (600 ft/mm) to 8 m/s (1600 ft/mm) are attainable dependent on airspeed and yaw.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
