Air Speeds Repair And Replacing The Indicator

By Ruth Green


Typically, the indicators of airspeeds can be replaced with another which is being produced by another manufacturer, as long as it has the same range and type. However, prior to performing the replacement processes, some important things must need to be considered. Two of the most common types of indicators which are being used are the Aerosonic and the Kollsman.

These 2 are considered to have longer cases than other manufacturers. But there may be possible problems during the installation in some aircraft types. On typical indicators like Pitot, inputs will pass into the center in the back of an indicator while static inputs are placed into the right, when viewing it from rear. The air speeds repair is being done using the easy steps. However, it could also be possible to encounter complicated steps sometimes, depending on what problem is to be resolved.

Airspeed indicator has one main purpose of letting the pilots make use of it in all the flight phases. These include if they descent, take off, cruise, climb, and land for maintaining the airspeeds. The parts are specific when it comes to the aircraft types and as well as to operating conditions being specified in the operating manuals.

During an instrument flight, an indicator will be used as an addition to artificial horizon as the instrument for reference of pitch control in descents, turns, and climbs. It could also be used in the dead reckoning. This is which speed, bearing, and time are being used to navigate when there are no aids including VORs, GPS, and NDBs.

Along with altimeters and vertical speed indicators, air speed indicators are some members in Pitot static systems for aviation instruments. Given name corresponds in the operations by pressure measurement of pilot and of static circuit. The functions of indicators will work through some differences of stagnation pressure and of static pressure. Impact pressure is being referred to these differences.

The static ports location is on aircraft exterior or the chosen location for detecting the prevailing pressure in the atmosphere with accuracy. Other types of aircrafts have static ports found on both sides on a fuselage or on an empennage for measuring the static pressure of slips and of skids. And thus, the result would be a more accurate information.

Airspeed indicators are available in many different variations and one of the most common is LRI or lift reserve indicator. This is a proposed alternative or proposed back up to ASI or airspeed indicator during critical flight stages. It is an elegant type of device and can be rarely found in a light aircraft and even in the transport jets. A conventional ASI has lesser sensitivity and accuracy as an airspeed diminishes. And thus, providing lesser reliable information to pilots during a stall.

The stall speed is varied depending on the conditions of the flight, specifically during gross weight changes and wing loading when maneuvering. The ASI does not have the capability of showing directly to the pilot how the stall is approached in maneuvering while the LRI will do. And thus, it becomes more descriptive and much easier for pilot use.

Both the dynamic differential pressures and attack angle will be used for the operations of LRI. It would be very much advantageous for the low airspeeds due to its extreme accuracy and it is fast acting. Thus, providing more reliable information.
