Question

What are NDB Service Volume Classes distance

A) Class A: 100 NM, Class B: 50 NM, Class C: 25 NM, Class D: 10 NM
B) Class A: 15 NM, Class B: 25 NM, Class C: 50 NM, Class D: 100 NM
C) Class A: 50 NM, Class B: 100 NM, Class C: 10 NM, Class D: 25 NM
D) Class A: 10 NM, Class B: 15 NM, Class C: 100 NM, Class D: 50 NM

Answer 1

None of the options provided in the question are entirely correct. NDB service volume classes are defined by specific distances that an NDB is reliable, which are not fully represented by the options given.

Step-by-step explanation:

The Non-Directional Beacon (NDB) service volume classes determine the distance over which an NDB is reliable. The correct distances associated with each NDB service volume class are:

Class A: 25 nautical miles (NM)

Class B: 50 nautical miles (NM)

Class C: 75 nautical miles (NM)

Class D: 25 nautical miles (NM) at and above 5000 feet AGL within the volume defined as a sector of 50.8 degrees extending from each side of the NDB radials

Therefore, none of the options A), B), C), or D) provided in the question are entirely correct regarding the NDB service volume classes. It's important to have accurate knowledge of these distances for navigational purposes in aviation.
