# Key Takeaways
- Typically autopilot can fly either lateral (single axis) or lateral+vertical (dual axis)
- Valuable tool for workload reduction
- Safe usage requires an understanding of risks associated with automation
# Details
1. Types of Autopilot
1. Dual Axis vs. Single Axis
2. Flight Directors
3. Benefits of Autopilot
1. Workload reduction
2. Fatigue management
3. Task Management
4. [[POH]] and [[AFM]] supplements pertaining to autopilot
1. Preflight check of autopilot
1. > [!note] Some autopilots include specific preflight steps, while others are surprisingly sparse
2. Generally good to check basic functionality and the ability to disconnect
3. Example GFC 500 [Autopilot Preflight Test](https://www.youtube.com/watch?v=PMRVKs64Rtw) by [Holladay Aviation](https://www.youtube.com/@HolladayAviation)
2. Autopilot usage, modes, GPS integration, altitude functions
3. Ways to disengage
4. Limitations from POH
5. [[VVM]]: Verbalize, Verify, Monitor
6. Autopilot Function Demonstrations (Sim or Plane)
1. Pitch and Roll
2. HDG
3. VS, FLC, ALT, VNV
4. NAV
5. APP, BC
## Autopilot Risks
1. Complacency
2. Unusual Attitude/Upset
3. Loss of Situational Awareness/Behind the Plane
4. Autopilot Surprise^[A term from [[Jeppesen Instrument-Commercial]] for when the autopilot does something unexpected. Related to [[Children of the Magenta Line]].]
***Demonstration of risks, completed in a simulator***
1. Stall
1. Bug High Altitude, Set VS+100, Throttle Idle, Engage Autopilot
2. Runaway Trim
1. Set runaway trip trim in failures on simulator
3. [[CFIT]]
