Autopilot and Flight Management Systems

Basics of Autopilot Functions

  • Automatic systems: Reference to a system functioning without manual input.
      - Key note: In the case of a rudder control weighing 66 pounds, the system requires manual input.
  • Yaw Damper: Part of the autopilot system that stabilizes the aircraft's yaw motion.
      - Engagement Conditions: Conditions under which the autopilot or yaw damper becomes disengaged.
      - Stall Warning: Activation when conditions indicative of a stall are present.
      - Loss of Yaw Damper Engagement: Signaled by a disagreement between AHRS (Attitude and Heading Reference System).

Trim Management

  • Trimming the Aircraft: Adjusting controls to maintain level flight without constant manual input.
      - Right Wing Down Message: Signal indicating the need to trim the right wing down.
      - Actions for Trimming:     - Retrain right aileron trim if indicated.
        -** Left aileron trim may also be needed based on conditions.
  • Ball Trimming: Importance of maintaining the aircraft's balance, noting slip or skid indications.
      - Timing for Trimming: Wait ten seconds after each adjustment to allow systems to stabilize before making further adjustments.

Flight Takeoff Protocols

  • Tow Bus Function:
      - Disconnects the autopilot when activated.
      - Moves flight director bars to reflect a pitch-up attitude based on the current flap position (noted protocol).
  • Heading Hold:
      - Maintains the set heading of the aircraft at takeoff.
      - Essential for straight ascent without turns.
  • Climb instructions: E.g., “Climb 400, then a right turn to zero three two.”
      - Ensures smooth navigation up to the set altitude.

Autopilot and Flight Director Interactions

  • TCS Switch (Touch Control Steering):
      - Allows pilots to manually control pitch and roll by temporarily overriding autopilot inputs.
      - Example Usage:
        - Set airspeed or bank angle before releasing the switch to maintain that new parameter.
  • Vertical Speed Control:
      - The ability to dial in a specific vertical speed while allowing autopilot to hold that adjustment.
      - Useful in managing descent or climb rates effectively.
  • Pilot Monitoring: TCS is beneficial for reducing workload during critical phases of flight, allowing one pilot to adjust systems while another monitors.

TCAS (Traffic Collision Avoidance System)

  • Range Settings:
      - 6 Nautical Mile Ring: First layer of intruder proximity alarms.
      - 12 Nautical Mile Ring: Secondary layer for further ranges.
  • Altitude Information:
      - Above selection indicates 9,995 feet above and 2,700 feet below.
      - Below selection reverses those numbers: 2,700 feet above and 9,999 feet below.
  • Usage Protocol: Autofunction in various aircraft models, like the Boeing 737 and RJ700, as well as manual selection in other aircraft types.

EFIS and Communication Settings

  • Couple Switch: Directs which EFIS provides data.
  • Radarscope Functionality:
      - Scan Width: The radar can scan 6 degrees from center on each side, with a total sweep of 45 degrees either side of center.
      - Total range of radar visibility: 350 degrees across.
  • RCT Switch Function (Radar): Activates to manage radar exposure when facing poor weather conditions, indicated by a color change to blue, warning against entry into those areas.

Miscellaneous Remarks

  • Acknowledgment of fatigue during intense training sessions.
  • Use of humor and informal language to facilitate learning and reduce stress—like comments on food or the discomfort of terminology.
