Question

How often must altimeters and altimetry devices be re-certified on aircraft operating under IFR or day VFR in Class B airspace?

a) Every 12 months
b) Every 24 months
c) Every 36 months
d) In the absence of manufacturer's recommendations, every 12 months

Answer 1

Altimeters and altimetry systems on aircraft operating under IFR or day VFR in Class B airspace must be re-certified every 24 months according to Federal Aviation Regulations to ensure accurate altitude reporting for air traffic control.

Step-by-step explanation:

In aviation regulation, the re-certification interval for altimeters and altimetry systems on aircraft operating under Instrument Flight Rules (IFR) or day Visual Flight Rules (VFR) in Class B airspace is every 24 months. This requirement is specified in the Federal Aviation Regulations (FARs), and it ensures that instruments critical to maintaining proper flight levels and safety in controlled airspace are functioning accurately. Aircraft must undergo this periodic inspection by appropriately certified maintenance personnel to ensure continued compliance with the established altitude reporting standards necessary for air traffic control.
