Airspeed Indicators
Airspeed indicators measure the difference between total pressure and static pressure.  The total (or measured) pressure is sensed by a pitot tube positioned at the stagnation point of the airstream and is carried to the airspeed indicator by a hose.  A static pressure sensor can also be connected.  The measuring element is an open diaphragm unit with excellent elastic properties; hysteresis (differences between advance and return movement) and secondary elastic effects are negligible.  The total pressure and static pressure act on the diaphragm, causing a deformation that is transferred to the pointer by a linkage and gear mechanism.  The different operating ranges of the aircraft can be identified by color markings on the airspeed indicator dial; e. g. green for normal operating range, yellow for caution, white for flaps down and red for maximum speed.  The instruments are insensitive to shock and vibration.

Airspeed Indicator Options:

• Units
  • Knots (standard)
  • Mph
  • km/h
• Size
  • 80 mm (3 1/8")
  • 57 mm (2 1/4")
• Speed Range
  • 0 to 100, 140, 160, 200, 220, or 250 knots
  • 0 to 120, 160, 180, 220, 250, or 280 mph
  • 0 to 200, 250, 300, 350, 400, or 450 km/h
• Single or Multiple Revolutions
  • 510° - standard, needle swings more than 1 turn to give more resolution.  Very popular in sailplanes.
  • 360° - single turn, easier to read, but less resolution.
• Zero Point
  • 12 o'clock, standard on non-metric models
  • 6 o'clock, standard on km/h units
• Operation Range Markings
  • None - Standard, See the W-7003-57mm, W-6003-80mm and OpRangeStickers-USA
  • Custom - Factory applied markings are great and not very expensive, but there is a 6 week lead-time.
• Großkinsky - Variable-Camberflap Ring
  • Optional ring which displays the recommended flap setting for defined airspeed ranges and is adjustable for wing loading. See the W-6001 and W-7001 above.
