With an extremely rapid ice build-up, select a suitable "off airport" landing site. 7. With an ice accumulation of 1/4 inch or more on the wing leading edges, be prepared for significantly higher stall speed. 8. Leave wing flaps retracted. With a severe ice build-up on the horizontal tail, the change in wing wake airflow direction caused by wing flap extension could result in a loss of elevator effective¬ness. 9. Open left window and, if practical, scrape ice from a portion of the windshield for visibility in the landing approach. 10. Perform a landing approach using a forward slip, if necessary, for improved visibility. 11. Approach at 65 to 75 KIAS depending upon the amount of the accumulation. 12. Perform a landing in level attitude. STATIC SOURCE BLOCKAGE (Erroneous Instrument Reading Suspected) 1. Alternate Static Source Valve -- PULL ON. 2. Airspeed -- Consult appropriate calibration tables in Section 5. LANDING WITH A FLAT MAIN TIRE 1. Approach -- NORMAL. 2. Touchdown -- GOOD TIRE FIRST, hold airplane off flat tire as long as possible. ELECTRICAL POWER SUPPLY SYSTEM MALFUNCTIONS OVER-VOLTAGE LIGHT ILLUMINATES 1. Avionics Power Switch -- OFF. 2. Master Switch -- OFF (both sides). 3. Master Switch -- ON. 4. Over-Voltage Light -- OFF. 5. Avionics Power Switch -- ON. If over-voltage light illuminates again: 6. Flight -- TERMINATE as soon as possible. CESSNA SECTION 3 MODEL 172N EMERGENCY PROCEDURES AMPLIFIED PROCEDURES ENGINE FAILURE 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 added safety after a failure of this type. Prompt lowering of the nose to maintain airspeed and establish a glide attitude is the first response to an engine failure after takeoff. In most cases, the landing should be planned straight ahead with only small changes in direction to avoid obstructions. Altitude and airspeed are seldom sufficient to execute a 180° gliding turn necessary to return to the runway. The checklist procedures assume that adequate time exists to secure the fuel and ignition systems prior to touchdown. 中国通航网 www.ga.cn 通航翻译 www.aviation.cn 本文链接地址：塞斯纳172飞行员操作手册 Cessna 172 PILOT'S OPERATING HANDBOOK(19) |
