(a) 65 knots above power off stall speed (b) 250 KIAS (c) 220 KIAS (d) 280 KIAS[[marked as correct answer]] 74. Which of the following statements is not true? (a) During all penetration descents, the use of idle RPM is encouraged (to conserve fuel.[[marked as correct answer]] (b) During takeoffs on runways with large amounts of puddled water, flameouts can be caused by water thrown up by the nosewheel. (c) To ensure effective anti-icing maintain a minimum of 80 per cent RPM when the engine anti-icing system is turned on. (d) Do not takeoff on slush-covered runways as the nosewheel may sling slush into the inlet ducts and cause engine flameout and/or damage. 75.
