Indicator Replacement For Air Speeds Repair

By Ruth Green


Typically, indicators in airspeeds are being replaced for some reasons. The item that will replace can be purchased from another manufacturer, but it must be of the same type and of range. However, before the process of replacement will be performed, there some things which you need to consider importantly. There are 2 most common indicators such as the Kollsman and the Aerosonic.

The two have longer cases compared to other manufacturers. However, these can possibly cause some installation problems in some aircrafts. On the typical indicators such as the Pitot, the input is through the center at the back of indicator and static input is placed to the right, if viewed from rear. Air speeds repair could be done through some easy steps, but difficulties and some complicated steps at times cannot be avoided, depending on the problem.

An airspeed indicator has the purpose of allowing the pilots in using it for all flight phases. Different phases include take off, climb, land, descent, and cruise. These can help in the maintenance of the airspeeds. Knowing about the aircraft types that should operate, and opportunity for you based on the specifications of operating manuals.

During instrument flights, an indicator has the purpose of being added to an artificial horizon similar to a reference instrument utilized in controlling pitch during descents, climbs, and turns. Another very common use is in a dead reckoning. Reckoning is where speed, time, and bearing will be utilized in navigating with no VORs, NBDs, and GPS aids.

Along with vertical speed indicators and with altimeters, airspeed indicators are members of Pitot static systems of the aviation instruments. The name corresponds to the operations through the measurement of pressure in static circuit and pilot. The indicators work through the differences between the static pressure and the stagnation pressure. The differences are referred to as impact pressure.

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 of different variations, lift reserve indicator or LRI is a very common type. This could be the best back up or alternative for an airspeed indicator or ASI during the critical stages in a flight. It is a device of an elegant type and is rarely being found in the light aircraft or even in transport jets. The conventional ASI type is less accurate and less sensitive when diminishing airspeed. And thus, an information that is reliable is provided to pilots during the 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.

Attack angle and dynamic differential pressures are being used by and LRI for its operation. This can be very advantageous for low airspeeds because it is extremely accurate and fast acting. And thus, much reliable information can be provided.
