In a flight database that I'm working with on a project, there is a column of data called "flightCategory" with values "C", "G", "T", etc. Any idea what those actually mean? From what I understand, the database is from FAA. But I'm not 100% sure.

    $\begingroup$ What is the database and what other columns are there? The context could help us. What are the rest of the values? Can you post the database? $\endgroup$

    $\begingroup$ Grasping at straws, I'm going to guess flight plan, and type of flight, 'G' being general aviation, 'C' I think used to be commercial, being replaced by 'S' for scheduled and 'N' for non-scheduled. But I'm not a flight plan connoisseur so I might be off the mark. Still leaves 'T' though. $\endgroup$

1 Answer 1


I got the answer. 'C' is commercial, 'G' general aviation, 'T' taxi, etc.


http://www.faa.gov/air_traffic/publications/atpubs/fss/AppendixA.htm, under section "Type of flight", it lists

S if scheduled air service

N if non­scheduled air transport operation

G if general aviation

M if military

X if other than any of the defined categories above.

But types C and T isn't there.

    $\begingroup$ Without context it's hard to determine if this answer is useful (at least "useful to anyone who isn't you") -- can you tell us more about the database you're working with? $\endgroup$

  • $\begingroup$ Initially I only know these abbreviated codes "C", "G", etc. and nothing else. Later I was told what they actually mean. The relevant engineer dug the information up from comments in source code. $\endgroup$

    $\begingroup$ You're missing the point of context - What database is this out of?, Who created/maintains it? etc. - without that context this question and answer aren't useful to the general public. $\endgroup$

  • $\begingroup$ That, honestly, I don't know. The only thing I've been let know is the data is from FAA. $\endgroup$

  • $\begingroup$ and where would you have found it? how does it look like? how is it named? $\endgroup$
