Visible moisture is defined as clouds, fog with visibility of less than one mile, rain, snow, sleet, and ice crystals. What Anti-ice/Deice equipment must be ON for all flight operations? Level 1 items Takeoff: You will enter Atmospheric Icing conditions prior to 1,500 ft AFL. What equipment must be ON? Level 2 items Takeoff: No Atmospheric Icing but there is Ground Icing. What equipment must be ON? Level 1 items Props 1 & 2 Continuous Relight AOA light extinguished Normal speeds may be bugged https://www.chegg.com/flashcards/atr-72-limitations-3799c874-b851-4d7c-93ee-212dca343522/deck 17/03/2023, 9:47 PM Page 7 of 14 At the first sign of ice formation, what Anti-ice/Deice equipment must be ON until five minutes after leaving Atmospheric Icing Conditions.

Level 1 items AOA light illuminated Icing speeds bugged and observed Flight Control Limitations (Flaps) Enroute flight operations, including holding, with the flaps extended are prohibited, except for single engine operations. This restriction applies regardless of atmospheric conditions. Ice Detection Lights All icing detection lights (ice evidence probe light and wing illumination lights) must be operative prior to flight at night in atmospheric icing conditions. Must the Ice Detector be operative for operations in atmospheric icing conditions? Yes When is Takeoff prohibited with When frost, snow or ice is adhering to https://www.chegg.com/flashcards/atr-72-limitations-3799c874-b851-4d7c-93ee-212dca343522/deck 17/03/2023, 9:47 PM Page 8 of 14 When is Takeoff prohibited with airframe contaminants? When frost, snow or ice is adhering to the wings, control surfaces, propellers, stabilizers, pitot static ports or alpha probes. When is Takeoff not authorized on a Contaminated runway? If standing water, slush, or wet snow on the required length or width of the runway is more than 1/2 in deep, or if dry snow accumulation is more than 4 in deep. What, if any, are the limitations with an operation ferry flight with the pitch elevators disconnected? Use of Type IV deicing fluid is prohibited. Severe Icing Primary Visual Cues Ice covering all, or a substantial part of the unheated portion of either forward side window, possibly associated with water splashing and streaming on the windshield. Severe Icing Primary Performance Cues Unexpected decrease in airspeed and/or rate of climb. Severe Icing Secondary Visual Cues Unusually extensive ice accretion on the airframe in areas not normally observed to collect ice, accumulation https://www.chegg.com/flashcards/atr-72-limitations-3799c874-b851-4d7c-93ee-212dca343522/deck 17/03/2023, 9:47 PM Page 9 of 14 of ice on the lower surface of the wing aft of the protected area, and accumulation of ice on the propeller spinner farther aft than normally observed. May the autopilot be used in severe icing? If not, why? The autopilot may mask tactile cues that indicate adverse changes in handling characteristics. Name the limitations for the Autopilot/Flight Director - A FD mode must be selected prior to autopilot engagement - Minimum height for AP engagement after Takeoff is 500 ft AFL - VOR Approaches using NAV mode with either the AP or FD is authorized only if: - A collocated DME is available, and - DME HOLD is not selected - Minimum height for AP or FD other times: - Except during T/O or executing an Approach: 1,000 ft AGL - APP, V/S, or IAS mode during Approach: 160 ft AFL Single DC Generator Operations In flight, if OAT exceeds ISA +25, flight level must be limited to FL 200.
