TURBOCOMMANDER 690B RG AVIATION

AIRCRAFT CHECKLIST

PREFLIGHT INSPECTION This preflight inspection is to be used with the Turbocommander 690B models. An essential part of the preparations made before any flight is the preflight inspection. During this inspection, verify the aircraft's physical readiness. A thorough preflight before the first flight of the day is critical to determine airworthiness and provide for the highest degree of safety. No detail should be overlooked during the first preflight of the day. Abnormal conditions (e.g., low tire pressure) must be corrected prior to flight. Even minor discrepancies should be rectified prior to flight to ensure safety. The preflight inspection begins inside the aircraft where the initial cockpit setup and essential functions are verified. The actual exterior inspection follows; it begins at the cabin door, proceeds clockwise around the aircraft, and ends at the left wing root. Lastly, the pilot returns to the interior of the aircraft to check the passenger compartment and cockpit for flight readiness.


AIRCRAFT CHECKLIST

CHECKLIST USAGE Tasks are executed in one of two ways: as a sequence that uses the layout of the cockpit controls and indicators as cues (i.e., “flow pattern”). as a sequence of tasks organized by event rather than panel location (e.g., After Takeoff, Gear – Gear – RETRACT, RETRACT, Flaps - UP). The placing of items in a flow pattern or series provides organization and serves as a memory aid. A challenge-respons challenge-response e review of the checklist follows execution execution of the tasks; the pilot monitoring (PM) calls the item, and the appropriate pilot responds by verifying its condition (e.g., Engine Anti-Ice [challenge] – ON – ON [response]). Two elements are inherent in the execution of normal procedures: use of either the cockpit layout or event cues to prompt the correct switch and/or control positions. use of normal checklists as “done” lists.

NORMAL PROCEDURES Normal operating procedures for Turbocommander 690B are presented in this section. In instances where the procedures vary model to model, the differences are noted. Limitations, cautions, and warnings are also included as applicable. Requirements for cold weather operations are also addressed.

CHECKLIST USAGE Tasks are executed in one of two ways: as a sequence that uses the layout of the cockpit controls and indicators as cues (i.e., "flow pattern"). as a sequence of tasks organized by event rather than panel location (e.g., After Takeoff, Gear – Gear – RETRACT, RETRACT, FLAPS - UP). The placing of items in a flow pattern or series provides organization and serves as a memory aid. A challenge-respons challenge-response e review of the checklist follows execution execution of the tasks; the pilot monitoring (PM) calls the item, and the appropriate pilot responds by verifying its condition (e.g., Engine Anti-Ice [challenge] – ON – ON [response]). Two elements are inherent in the execution of normal procedures: use of either the cockpit layout or event cues to prompt the correct switch and/or control positions. use of normal checklists as "done" lists.

NOTE: Turning engine control switch OFF before turning generator switch OFF will unnecessarily break and make generator line and field relay contacts, thereby reducing contact service life.

CAUTION: Placing the engine control switch to the ENG OFF position following manual shutdown (condition lever to FEATHER position), will result in a fuel accumulation in the plenum and may result in smoke and a loud popping sound. It is recommended that the engine control switch not be placed in the ENG OFF position until engine cools well below 300°C to prevent combustion. NOTE: Engine RPM should increase approximately 5% with placement of the engine control switch to the ENG OFF position, and then decrease when the manifold fuel is depleted. NOTE: If power lever is not placed in reverse the propeller will feather.

NOTE: The battery switch must be OFF, or the cabin door switch must be placed in the UNLOCK position before the cabin door can be opened. The door annunciator will illuminate if the battery is ON and entry door is not secure or the door lock switch is in the UNLOCK position. WARNING: Do not open the cabin door until the left propeller stops rotating.

CAUTION: If engine is to be restarted within 10 to 45 minutes after shutdown, observe engine compressor and slowly move propeller until compressor rotates one half revolution. Propeller tip will move approximately six (6) inches. This should be done approximately ten (10) minutes prior to restart.
