Does an FBO altimeter require a bi-annual check?

Asked by: 2531 views FAA Regulations, General Aviation

Does an altimeter sitting on a counter in a FBO at an non-towered/uncontrolled airport where the FBO personnel read the altimeter setting via Unicom to an aircraft shooting a CAT I approach require a bi-annual check or any type certification?

    I don’t know the frequency the certification is required, but it is definitely required. Before we had an ASOS, we used two altimeters mounted on a shake table. They had to be set to the location elevation and the Kollsman window values had to agree after the vibrate was turned off. It has been a while since we did this at the FBO and I don’t know if it is still OK to do this.
