Altimeters

With reference to the Altimeters, consider the following statements:

1. It operates in the 4.2-4.4 GHz range
2. Altimeter readouts are also used to facilitate automated landings and to help detect dangerous currents called wind shear.

Which of the statements given above is/are correct?

A. 1 only
B. 2 only
C. Both 1 and 2
D. Neither 1 nor 2

Answer: Both 1 and 2

Explanation:  The chief executives of major US passenger and cargo airlines have warned of a “catastrophic” aviation crisis this week as AT&T and Verizon deploy new 5G services.

They said the new C band 5G service set to begin could render a significant number of aircraft unusable, causing chaos for US flights and potentially stranding tens of thousands of Americans overseas.

The US Federal Aviation Administration (FAA) has warned that the new 5G technology could interfere with instruments such as altimeters, which measure how far above the ground an airplane is travelling.

Altimeters operate in the 4.2-4.4 GHz range and the concern is that the auctioned frequencies sit too close to this range.

In addition to altitude, altimeter readouts are also used to facilitate automated landings and to help detect dangerous currents called wind shear.
