Section 1 - DESCRIPTION GENERAL a. The Me-262 is a single-place, jet-propelled aircraft used as a fighter-bomber. The low swept-back wing is a symmetrical airfoil section with square tips. Automatic leading edge wing slots are incorporated in the wing design. The fuselage of of the Me-262 is triangle shaped with an unusually long nose, and a tail assembly of a single fin and rudder. The undercarriage is a squat tricycle type. Power is provided by two propulsion units under the wing. b.
c. Wing flaps. (1) The Handley-Page type flaps are operated by two push buttons. (See fig. 3-2). Flap position is indicated by graduations of 0°, 10% 20°, 30°, 40% and 50° marked on the upper surface of the flap; the 20° position used for take-off is marked in red. (2) Emergency lowering of the wing flaps is accomplished by the use of an emergency compressed air system. Operation is accomplished by opening the operating handle (See fig. 2-2), two complete turns.
HYDRAULIC SYSTEM CONTROLS a. The engine driven hydraulic pump is in operation whenever the port engine, to which it is attached, is operating. Because of the low capacity of the pump, operation of the landing gear is slow, and time allowance must be considered when approaching for a landing. b. Hydraulic power is used to operate the flaps and landing gear. c. A compressed air emergency system is incorporated to be used for lowering flaps and landing gear in event of failure of the hydraulic system.
c. Fuel transfer is accomplished by operation of the push button switch located in the main switch panel. (See fig. 4-2). Fuel is transferred from the rear auxiliary tank to the main fuel tanks only. Transfer from the auxiliary fuel tank located beneath the pilots' compartment is accomplished by pumping into the rear auxiliary tank and then into the main fuel tanks, Fuel transfer is automatic upon operation of the fuel transfer switch. Fuel is transferred at unequal rates into the forward fue1 tank.
Section 2 - PILOT OPERATING INSTRUCTIONS BEFORE ENTERING PILOT"S COMPARTMENT a. Flight Restrictions: Only normal flying maneuvers should be performed with this airplane until further data is obtained. No high-speed dives should be run. b. Air-Speed Limitations: The maximum allowable airspeed (IAS) is 950 km/hr (590 mph.) c. Center of Gravity Position: With the three forward fuel tanks full and the rear one empty, the best center of gravity position will be maintained. This is 156 in. aft of the nose.
(8) Generator switches (See fig. 4-11 and 12) "on". (9) Pitot heat switch (See fig. 4-8) "off." (10) b. External power source connected. Special Check for night flying: (1) Navigation lights (See fig. 4-7). FUEL SYSTEM MANAGEMENT a. Fuel Selector Switches: The fuel valve controls, (See fig. 2-10) have three positions; rear position fuel shut off; center position rear main fuel tank; and forward position front main fuel tank.
Note: b. Electric fuel pumps are provided and can be used in cold weather conditions when unit is hard to start. These pumps supply gasoline to the burners. They should be shut off when a speed of 3000 rpm is reached. (3) Turn fuel selector valve "off". (4) Throttles closed. (5) Push down starter handle to prime Riedel starting motor. (6) Pull starter handle and hold; at the same time press tachometer button and hold. This puts tachometer in low speed range.
TAXIING a. Caution must be used in taxiing because the rudder is ineffective and steering by engine thrust is difficult as thrust builds up too slowly. Brakes are the only means of control, and taxiing should be done with jet units running at 4000 to 6000 rpm. The tail of the ship must not be turned toward inflammable objects. TAKE-OFF (1) Hold aircraft with main wheel brakes and open throttles very slowly to 7000 rpm. (2) Release brakes and open throttles fully.
GENERAL FLYING CHARACTERISTICS a. Stability: (1) This airplane has good aileron control at all altitudes and will do a good slow roll. (2) The airplane holds its speed in tight turns much longer than conventional types. (3) In climbing or turning, automatic slots in the leading edge of the wing open when the speed drops to 450 km/hr (280 mph). Slots open at 300 km/hr (185 mph) when the airplane is in a gliding angle. b.
b. Speeds of 950 km/hr (590 mph) are reported to have been attained in a shallow dive 20° to 30° from the horizontal. No vertical dives were made. At speeds of 950 to 1000 km/hr (590 to 620 mph) the air flow around the aircraft reaches the speed of shound, and it is reported that the control surfaces no longer effect the direction of flight. The results vary with different airplanes; some wing over and dive while others dive gradually.
(1) Reduce airspeed to 300 km/hr (186mph). (2) Throttle closed. (3) Turn on fuel pump. (4) Press ignition button throttle until rpm increases by 1000. (5) Open fuel selector valve. (6) Advance throttle slowly to idling position. (7) Release ignition button when rpm is constant. (8) Adjust rpm to that of other unit. APPROACH AND LANDING a. Normal Landing: Do not lower landing gear above 4000 km/hr (248 mph).
(2) Shut off fuel selector valves. (3) Open fuel dump valve switches. In the event that power units should begin to burn, pull starter handles, re-ignite power plant and then repeat above shutting down process. BEFORE LEAVING THE PILOT'S COMPARTMENT a. Turn all switches off. www.zenoswarbirdvideos.
Section 3 - FLIGHT OPERATING DATA ENGINE OPERATING DATA Airplane Model Me-262 A-l Condition Exhaust Gas Temperature Fuel Pump Pressure Maximum 650°C. 80 kg/cm2 Maximum ---- 50 kg/cm2 Minimum Fuel Grade Jet engines: AN-F-32 Riedel starters: AN-F-23 (with % pt of engine oil added to each gallon). Oil Grade AAF Spec. No.
Section 4 - EMERGENCY OPERATING INSTRUCTIONS FLIGHT ON ONE JET UNIT a. The aircraft will fly at 450 to 500 km/hr (280 to 310 mph) on one jet unit. It operates best over 3 km (10,000 ft). b. The minimum single engine speed of 260 km/hr can only be reached by climbing too steeply or with landing gear down. c. Bank only in the direction of the good jet unit unless speeds over 260 km/hr (160 mph) are maintained. EMERGENCY SHUTDOWN OF JET UNIT DURING FLIGHT a. Jerk throttle closed. b.
LANDING WITH ONE JET UNIT a. Approach the field, turning in the direction of the good jet unit. b. Lower the landing gear by compressed air (two complete turns of air valve) when 3 to 4 km (2 to 2.5 miles) out on the land ing approach. Main gear goes down in 2 to 3 sec and the nose wheel goes down in 5 to 10 sec. c. Lower flaps as needed, as the airplane will not go around again on one jet unit. d.
Causes: (2) (b) Drop in fuel pressure. (c) Drop in gas pressure. (d) Drop in tail-pipe gas temperature and trailing of white smoke. (a) Throttle pulled back further than idling position. (b) Stoppage of fuel supply. (c) Insufficient injection pressure at high altitudes. Broken vanes in jet unit: Indicated by: Vibration of the unit. Action: Turn off the jet to prevent the fuel lines from breaking and causing a fire.
(6) Thrust governor inoperative or the nozzle pin adjustment broken, in either case the thrust nozzle pin advances to the final notch: Indicated by: Action: (7) (a) Fuel pressure increases rapidly. (b) Gas pressure increases rapidly. (c) Gas temperature increases rapidly. Turn off the jet unit immediately avoid fire. Landing gear retraction trouble: (a) If the landing gear does not come up when the button is again pressed, reduce the speed to 160 mph and suddenly push down the nose.

Section 5 - OPERATIONAL EQUIPMENT HEATING AND VENTILATING a. Heating of the cockpit is obtained by operation of the control marked "Cabin Heat". (See fig. 1-11). b. Ventilating is accomplished by opening a small air scoop on the upper left of the fuselage just forward of the canopy. The scoop is operated by means of a control lever. (See fig. 1-18.) OXYGEN SYSTEM a. This is a standard low pressure oxygen system with a diluter demand oxygen pressure breathing regulator, Type A-14. b.
