What is the ARN-118 TACAN?
|
TACAN Navigational Set AN/ARN-l18(V) is a
polar coordinate navigation system. It is used to determine the relative bearing and/or slant-range distance to a TACAN ground station or cooperating the interrogating aircraft. The TACAN system operaircraft. |

which of the following describes the ARN-118?
a. The TACAN system operating range limit is satcom and depends on satelite altitude and type of aircraft. b. The TACAN system operating range limit is line of sight and depends on aircraft altitude and type of terrain. c. The TACAN system operating range limit is satcom and depends on aircraft altitude and type of aircraft. d. The TACAN system operating range limit is line of sight and depends on satelite altitude and type of aircraft. |
