Question

What does 3155-13 indicate on a FD?

a. Temperature 31.55°F, Dew point -13°F
b. Wind direction 315°, Altitude -13,000 feet
c. Runway 31, Length 55, Elevation -13 feet
d. Barometric pressure 31.55 inHg, Altitude -13,000 feet

Answer 1

Without additional context, it is not possible to definitively interpret the meaning of '3155-13' on a Flight Directory (FD). The usual notations for weather, navigational aids, or barometric settings do not precisely match with this string, especially with a negative value at the end.

Step-by-step explanation:

The string 3155-13 on a Flight Directory (FD) could indicate various types of data, depending on the context it is used. However, given the options provided and knowledge of aviation terminology and weather reporting, the correct interpretation is not clear-cut from the options provided. The string could be mistakenly taken for an altimeter setting (barometric pressure) which would be depicted as 31.55 inHg, but it is uncommon to see negative altitude in such reports, making this match unlikely.

Unfortunately, without additional context or clarification, it is not possible to provide a definite answer to what 3155-13 indicates on an FD. It is suggested to refer to the specific documentation or instructional material from which the string was taken to determine its meaning.
