How to read vfr flight instruments

  1. 1. James White 2/10/2013 TWC 400
  2. 2.  What are flight instruments? ◦ Why do we need them? Instrument Layout The instruments, one-by-one. Conclusion
  3. 3.  Instruments in the aircraft ◦ Gives information about the airplane’s flight situation ◦ Altimeter ◦ Attitude Indicator ◦ Turn Coordinator ◦ Heading Indicator ◦ Vertical Speed Indicator Used in particularly poor visibility ◦ i.e. clouds, or no outside visual reference points.
  4. 4.  Called the six pack
  5. 5.  Provide the source of ambient air pressure ◦ Operates; Airspeed Indicator, VSI and Altimeter Takes impact air pressure from moving forward. ◦ Pressure is changed and thus the instruments are affected.
  6. 6.  Measures the height of the aircraft ◦ Above a given pressure level Adjustable for local barometric readings ◦ Must be set correctly during pre-flight As the static-pressure drops, due to an increase in altitutde, capsules inside expand showing a high altiude reading. Non Standard pressure and temps affect it.
  7. 7.  To set: Turn knob on bottom left To read: Big hand reads 100s of feet, while little hand reads 1000s, the really thin one is 10’s of thousands
  8. 8.  Vertical Speed Indicator ◦ Indicates whether or not the aircraft is in level flight or not Shows two things ◦ Whether or not if you’re in a climb ◦ If so, the rate of said climb or descent. How to read: ◦ Up=climb ◦ Down=descent ◦ Read in 100s of feet/min
  9. 9.  Measures aircraft speed (in knots) relative to surrounding air. To read: ◦ White arc-flap operating Range ◦ Green Arc- Normal operation ◦ Yellow Arc- Caution
  10. 10.  Instruments that utilize the properties of gyroscopes ◦ turn coordinator ◦ heading indicator ◦ attitude indicator
  11. 11.  Gives information on the rate and direction of the turn you’re in. ◦ Also show’s if turn is coordinated  Pilot will use more or less rudder to correct How to read: ◦ The plane moves left for left  And vice versa ◦ The ball shows if the plane is in a slip or not ◦ 2 minutes to make a 360 turn.
  12. 12.  Artificial Horizon ◦ Relationship of mini airplane to horizon, the real relationship of airplane to horizon. Shows how level wings are, and if there’s a climb or not. Throughout flight, ball will move and show pitch attitude and degrees of bank. How to read: ◦ Blue is sky, brown is ground.  Numbers are degrees of attitude ◦ Top hashes are degrees of bank.
  13. 13.  Heading Gryo ◦ Principle direction instrument used in flight ◦ Not affected by banks, speed changes etc ◦ NOT MAGNETIC How to read: ◦ Just like a compass. ◦ Front of aircraft is the direction
  14. 14.  There’s two types of instruments ◦ Gyro and Pitot-Static Instruments help in VFR conditions Known as the 6 pack Know these like back of hand One step closer to getting in that plane and flying it.
