Winter Instruments 6 FMS Airspeed Indicator (ASI) 80mm

General Description

Winter Instruments 6 FMS Airspeed Indicator 80mm - 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 effect total pressure and static pressure acts 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. The instruments are insensitive to shock and vibration.

The most popular 80 mm ASI in the USA is 6423. W&W typically stocks the ASI models highlighted in the table (6212 @12 O'clock and 6423 @12 O'clock). *Please allow approximately 4 weeks Winter production time for other ASI models and Factory Color Marked Airspeed Indicators.

Airspeed Indicatiors come in two different sizes:

Technical Data

Purpose: Pitot airspeed indicator for indication of the relative airspeed of gliders and micro–lights.

Principal mode of operation: The instrument works by measurement of the pitot pressure, by means of an open diaphragm cell, as difference between total pressure and static pressure.

Scale graduation:

  • 6 FMS 2 and 6 FMS 5: 360° scale with linear graduation
  • 6 FMS 4: 510° scale with non–linear graduation

Weight: 6 FMS 2, 6 FMS 4 and 6 FMS 5: 0,2 kg

Indication errors:

  1. at room temperature: 0–100 km/h:± 2 km/h above 100 km/h: ± 3 km/h
  2. at –30°C to + 50°C: 0–100 km/h:± 3 km/h above 100 km/h: ± 5 km/h

Factory Color Marking

Color markings can be put on the instrument scale to identify the operating ranges and the limiting performance of the aircraft. The type series numbers given in the above table are only applicable to types 6 FMS 2, 6 FMS 4 and 6 FMS 5 airspeed indicators without color marking on the indicator scale. In all other cases, the part number should be obtained from the technical documents of the aircraft manufacturer or by checking with Gebr. Winter & Co. KG.

*Please allow approximately 4 weeks Winter Instruments production time for Factory Installed Color Markings.

Grosskinsky Variable Camberflap Ring

Grosskinsky Variable Camberflap Ring - As is generally known, wing load and, in turn, the optimum flap positions for the various speed ranges of a variable-flap glider changes with take-off weight. Until now, selecting the right flap position has ivolved using special tables carried on board or observing a confusingly large number of marks on the airspeed indicator. The new adjustable ring for airspeed indicators makes these complicated methods things of the past.

*Please allow approximately 4 weeks Winter Instruments production time for Grosskinsky Variable Camberflap RIngs.

Maintenance Insructions

Leak Testing should be carried out at least every 2 years. Otherwise, the instrument does not require any maintenance.

The manufacturer recommends airspeed indicators be subject to retesting after 5 years.

Retesting and Repair

The service condition and accuracy of measurement of the ASI is normally retained over a long period. For obvious malfunction the unit should be subjected to an investigation at the manufacturer or a suitable aircraft engineering company. It should be packed to protect it from impacts and connections should be sealed. Under no circumstances should you interfere with the measuring mechanism of the airspeed indicator.

Appliction Limits

Maximum operating height: 12.000 m

Operating temperature range: –30°C to + 50°C

Magnetic Effect: No deflection of the compass needle at any distance between airspeed indicator and aircraft compass.

Overpressure resistance: The maximum indicated airspeed may be exceeded by 20%.

Vibration resistance: 5 – 50 Hz: maximum amplitude 0,25 m

maximum acceleration 1,5 g

50 – 400 Hz: maximum acceleration 0,5 g
