ATSC 231 - BLOCK 4 – ICING EXAM REVIEW QUESTIONS AND ANSWERS, GRADED A+ What is an airplane's response to a tailplane stall? - -a rapid pitching down motion Aircraft that are certified for flight into known icing conditions have systems that keep the windscreen (or portions thereof) clear of ice. - -true Which of the following is an indication that the ice accretion on an airplane in flight is a result of supercooled large drops (SLDs)? - -ice aft of protected areas Ice will accumulate on the leading edge of the wing before it accumulates on the horizontal stabilizer. - -false Aircraft are required to demonstrate stall characteristics in natural icing conditions during icing certification tests. - -false When should pitot heat be activated (in relation to icing conditions)? - -before icing is encountered When should de-icing systems be operated? - -after icing is encountered When should anti-icing systems be activated? - -before icing is encountered Which condition is most favorable for tailplane stall? - -flap deployment How does an increase in the angle attack of an airfoil change its collection efficiency? - -it increases the collection efficiency What is the antidote for inlet icing for turbine powered airplanes? - -anti-ice What type of airplanes are affected by inlet icing? - -all of the above (piston powered fuel injected airplanes, piston powered normally aspirated airplanes, turboprop airplanes, turbojet and turbofan airplanes) The majority of part 91 icing accidents were fatal as documented in the NTSB statistical analysis of icing accidents. - -false Icing caused what percentage of part 91 aircraft accidents as documented by the NTSB? - -9% What is the antidote for carburetor icing? - -turn on carb heat What are the symptoms of inlet icing for a fixed pitch propeller airplane? - -gradual loss of power (RPM) and engine roughness Carb icing occurs only in visible moisture. - -Fals
