Minor Little Questions

I hate to use up numerous topics for little piddly questions that take one sentence to ask and one sentence to answer.

This question is ‘piddly’.

What kind of destination airport is “(2031/10318)”? See N236CA, departed KADS at 3:50 PM CST.

If anyone else has ‘piddly’ questions, please join in here.
