| + | |||
| + | Deviation: caused by local magnetic fields within the aircraft. Deviation error is different on each heading | ||
| + | |||
| + | Deviation card shows what the mechanics are unable to correct/adjust. | ||
| + | |||
| + | Magnetic Dip: indication errors caused by an unbalanced compass | ||
| + | |||
| + | Teter-totter balance analogy--@magnetic equator north and south forces are balanced. Increase latitude, north pole is pulling down more than south pole. | ||
| + | |||
| + | Above 60° latitude, compass is unusable—too much dip | ||

| + | ==== Common Errors ==== | ||
| + | |||
| + | - Failure to keep the airplane properly trimmed. A cockpit interruption when you are holding pressures can easily lead to inadvertent entry into unusual attitudes. | ||
| + | - Disorganized cockpit. Hunting for charts, logs, computers, etc., can seriously detract your attention from the instruments. | ||
| + | - Slow cross-check and fixations. Your impulse is to stop and stare when you note an instrument discrepancy unless you have trained enough to develop the skill required for immediate recognition. | ||

| ===== Magnetic Compass Turns ===== | ===== Magnetic Compass Turns ===== | ||
| + | |||
| + | When making a turn from a northerly heading, the compass briefly gives an indication of a turn in the opposite direction. When making a turn from the south, it gives an indication of a turn in the correct direction but at a faster rate. | ||
| ===== Timed Turns ===== | ===== Timed Turns ===== | ||
| + | |||
| + | Standard Rate Turns: 3°heading/second: 2 minutes for 360° turn. | ||
| + | |||
| + | Bank angle required: Standard rate turns: 15% of TAS or ~20% IAS (easier to calculate) | ||
