Airspeed -- 60 KIAS. Carburetor Heat -- ON. Section 3 provides checklist and amplified procedures for coping with emergencies 3. Emergencies caused by airplane or engine malfunctions are extremely rare if 4. Fuel Shutoff Valve -- ON. Enroute weather emergencies can 5.
Mixture -- RICH. However, should an emergency arise, the basic guidelines described in this section should be considered and applied as necessary to correct the problem.. Maximum Glide Ignition Switch -- OFF. Precautionary Landing With Engine Power Landing Without Engine Power: 6. Master Switch -- OFF. Wing Flaps Up Wing Flaps Down Throttle -- IDLE.
Airspeed -- 55 KIAS. Page Page 5. If necessary, open windows and flood cabin to equalize pressure so doors can be opened.
If fire appears out and electrical power is necessary for continuance of flight: 6. Master Switch -- ON. If engine starts: 9. Power -- RPM for a few minutes. After discharging an extinguisher within a closed cabin, 8. Turn pitot heat switch ON if installed. Turn back or change altitude to obtain an outside air temperature that is less conducive to icing. Pull cabin heat control full out to obtain maximum defroster air temperature.
For greater air flow at reduced temperatures, adjust the cabin air control as required. Ammeter Indicates Discharge 4. Open the throttle to increase engine speed and minimize ice buildup on propeller blades. Watch for signs of carburetor air filter ice and apply carburetor heat as required. An NOTE unexpected loss in engine speed could be caused by carburetor ice or air intake filter ice.
Lean the mixture for maximum RPM, if carburetor heat is used continuously. Illumination of the low-voltage light may occur during low RPM conditions with an electrical 6. Plan a landing at the nearest airport. With an extremely rapid ice build-up, select a load on the system such as during a low RPM taxi. Under these conditions, the light will go suitable "off airport" landing site.
The master switch need not be recycled since an over-voltage condition 7. Leave wing flaps retracted. With a severe ice build-up on the horizontal tail, the change 1. Radios -- OFF. Master Switch -- OFF both sides. Open left window and, if practical, scrape ice from a portion of the windshield for 4. Radios -- ON. Perform a landing approach using a forward slip, if necessary, for improved visibility.
Approach at 65 to 75 KIAS depending upon the amount of ice accumulation. If low-voltage light illuminates again: Perform a landing in level attitude. Alternator -- OFF. If an engine failure occurs during the takeoff run, the most important thing to do is stop the airplane on the remaining runway.
Those extra items on the checklist will provide Before attempting an "off airport" landing with engine power available, one should added safety after a failure of this type.
In most cases, the landing should be planned straight ahead with only small changes in direction to avoid obstructions. Altitude and Prepare for ditching by securing or jettisoning heavy objects located in the baggage airspeed are seldom sufficient to execute a gliding turn necessary to return to the runway. Transmit The checklist procedures assume that adequate time exists to secure the fuel and ignition Mayday message on Avoid a landing flare because of difficulty in judging height over a water surface.
After an engine failure in flight, the best glide speed as shown in figure should be established as quickly as possible. While gliding toward a suitable landing area, an effort should be made to identify the cause of the failure. If the engine cannot be restarted, a forced landing without power must be completed.
Trim for horizontal flight with an airspeed of approximately 55 KIAS and flaps lowered to by using throttle and elevator trim controls. Then do not change the elevator trim control setting; control the glide angle by adjusting power exclusively. At flareout, the nose-down moment resulting from power reduction is an adverse factor and the airplane may hit on the nose wheel.
Consequently, at flareout, the trim control should be set at the full nose-up position and the power adjusted so that the airplane will rotate to the horizontal attitude for touchdown. Close the throttle at touchdown. FIRES Although engine fires are extremely rare in flight, the steps of the appropriate checklist should be followed if one is encountered. After completion of this procedure, execute a forced landing. Do not attempt to restart the engine. The initial indication of an electrical fire is usually the odor of burning insulation.
The checklist for this problem should result in elimination of the fire. Page Page 7. Upon breaking out of clouds, resume normal cruising flight. The following instructions assume that only the electrically- If a spiral is encountered, proceed as follows: powered turn coordinator is operative, and that the pilot is not completely proficient in 1.
Close the throttle. Stop the turn by using coordinated aileron and rudder control to align the symbolic airplane in the turn coordinator with the horizon reference line. Cautiously apply elevator backpressure to slowly reduce the airspeed to 70 KIAS.
Adjust the elevator trim control to maintain a 70 KIAS glide. Upon inadvertently entering the clouds, an immediate plan should be made to turn back as 5. Keep hands off the control wheel, using rudder control to hold a straight heading. Apply carburetor heat. Clear engine occasionally, but avoid using enough power to disturb the trimmed glide. Note the compass heading. Note the time of the minute hand and observe the position of the sweep second hand on the clock.
When the sweep second hand indicates the nearest half-minute, initiate a standard rate left turn, holding the turn coordinator symbolic airplane wing opposite the lower left Flight into icing conditions is prohibited. An inadvertent encounter with these conditions can index mark for 60 seconds.
Then roll back to level flight by leveling the miniature best be handled using the checklist procedures. The best procedure, of course. Check accuracy of the turn by observing the compass heading which should be the reciprocal of the original heading. If necessary, adjust heading primarily with skidding motions rather than rolling motions SPINS so that the compass will read more accurately.
Maintain altitude and airspeed by cautious application of elevator control. Avoid Should an inadvertent spin occur, the following recovery procedure overcontrolling by keeping the hands off the control wheel as much as possible and should be used: steering only with rudder. If possible, obtain radio clearance for an 4. Full down westerly heading to minimize compass card swings due to changing bank angles.
In addition, elevator may be required at aft center of gravity loadings to assure optimum recoveries. Premature the turn coordinator. Occasionally check the compass heading and make minor corrections to relaxation of the control inputs may extend the recovery. Before descending into the clouds, set up a stabilized let-down 6. Apply full rich mixture. NOTE 2.
Use full carburetor heat. If disorientation precludes a visual determination of the direction of rotation, the 4.
