[[left alignment]] 13. (approach plates). Things to check pre-descent: 1. field elevation & safe altitudes 2. runway length & width 3. nav aids for approach 4. minimums for approach 5. details of approach 6. missed approach instructions 14. compasses & modes: whiskey compass- permanent magnet floating in oil (not reliable during turns, acceleration-dip angle) HSI compass card- gyro that's slaved through a servo loop to magnetic north (Error signals -> torque gyro). MAG position = slaved ("always" in this position) DIRECT GYRO = not slaved (still a gyro, but disconnected from servo loop... free to drift precess). FAST SLAVE = increased gain in servo loop 15. ADI & standby ADI both work on gyros with error sensing in 2-axes. "FAST ERECT" ups the gain to right the ADI level flight)... takes 2 min. [[/left alignment]]
