  1. INSTRUMENTS ALTIMETER

  2. ALTIMETER ALTIMETER If you increase your altimeter setting! 29.92 30.42 Your needle will increase. Therefore, you were indicating too low! HOW MANY FEET TOO LOW? You were indicating 500 feet too low!

  3. EXAMPLE NUMBER 2

  4. ALTIMETER ALTIMETER If you decrease your altimeter setting! 30.57 29.89 Your needle will decrease. Therefore, you were indicating too high! HOW MANY FEET TOO HIGH? You were indicating 680feet too high!

  5. EXAMPLE How do you find your PA? (pressure altitude)

  6. To find your PA, you need to set your subscale to 29.92! ALTIMETER ALTIMETER In this example, your needle will decrease. 30.15 29.92 IF YOUR FIELD ELEVATION IS 653’ ASL, WHAT IS YOUR PA? Your PA is 423’ ASL, therefore the your plane thinks it’s at 423’ ASL and not 653’ ASL.

  7. THE END
