Airspeeds- Selecting a Replacement Indicator

Airspeeds – Selecting a Replacement Indicator


Typically, you can replace any airspeed indicator with another manufacturer’s indicator of the same type and range. However, there are some considerations, which should be taken into account.

Aerosonic and Kollsman indicators often have a longer case than other manufacturers, this could cause an installation problem in some aircraft.

On typical indicators the Pitot input will be in the center of the back of the indicator, with the Static input to the right, when viewed from the rear. Occasionally you will find some older indicators where this was reversed. This may cause installation difficulties on some aircraft.

TGH Aviation offers custom range markings for all blank-dial instruments (most commonly, factory new units) and re-screening services on used instruments in need of refreshed or adjusted range markings.
