TRAINING M ANUAL– L ANCAIR IV/IVPOPERATION OF THE LANCAIR IV-POperating the pressurized LIV-P above 10,000 feet requires the pilot be awarethat a gradual loss of cabin pressure may not be recognized, if reference to thecabin pressure indicator is not maintained. The first indication may be the“popping” of ears and/or gradual onset of hypoxia. Include the cabin pressureinstruments in your scan pattern. Always check the instruments when your earstell you of a pressure change.If cabin pressure loss is gradual, after checking the pressurization controls inproper positions:1. Don oxygen mask, check flow (100%) inform passengers.2. Inform ATC of the problem and request lower altitude.3. Make normal descent, keeping turbos at maximum output, consistent withdescent rate and airspeed limitations.4. Consider terrain and level off at 2,000’ AGL or 10,000 MSL whichever ishigherIf cabin pressure loss is rapid:1. Don oxygen mask – check flow (100%), inform passengers.2. Auto pilot off.3. Turn 90 degrees from airway course, if flying airways.4. Set transponder to code 7700.5. Reduce power to minimum.6. Configure aircraft for maximum sink rate.a. Consider aircraft structure. If sound:(1) Increase pitch down until reaching maximum allowableairspeed.b. If aircraft structure has sustained damage:(1) Reduce speed to lowest practical speed.(2) Lower flaps and gear for low speed and high sink rate.‐ 24 – © Copyright 2007 LOBOMay not be copied without permission. |
