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.
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.
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.
Together with the vertical speed indicators and the altimeters, the indicators of air speed are members of Pitot static systems in aviation instruments. Its namea is corresponding to operations through measuring the pressure of the static circuit and the pilot. Indicators function because of differences in static pressure and stagnation pressure. These differences are called impact pressure.
On the exterior of an aircraft is where static ports are the location, or the location chosen for detecting prevailing atmospheric pressure as accurate. While for other aircrafts, the static ports are located in both of the sides of fuselage or empennage in order to measure slips and skids. And for sure the result is providing 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 speed of stall is being varied according to the flight conditions, specifically to the changes of gross weight and the wing loading in maneuvers. An ASI cannot show directly the pilot how a stall will be approached during maneuvers while an LRI does. And thus, making it more descriptive or much easier for use of pilots.
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.
