Does "kalkmak" also mean "to stand up"?
It does indeed. It Turkey buses "stand up" when they are going :D
Does the second k in kalkmak come from some kind of suffix? I realized that kalmak and kalkmak are quite close.
Kalacak mısın yoksa kalkacak mısın?
'Kalmak' and 'kalkmak' are two different words, it is not a suffix. Kalmak means to stay or to remain and kalkmak means to get up, to stand up or to depart.
Why is 'departs' not accepted?
because the suffix -acak means that the tense is future, so it should be "WILL"
Is the word "saat" not necessary?
It is totally optional. :)
What's the suffix that's been added to dört to mean at four?
That's the locative suffix:
After the consonants f, k, p, s, ş, h, and t the letter "d" of the suffix -de/-da changes to t:
sen en iyisin.
Do you have a good reference to learn all the sufiix and it's rules.
Turkish team time is great but doesn't cover the entire suffix list.
Sağol. Glad to help. I have a good selfstudy coursebook but that's in German...
Oh, I am native German. Could you please give me title or ISBN number of it. That would be great

How about "The bus is leaving at four"? Why it's incorrect?
You are using continous time "is leaving". The ending is future, so it must be "will leave" or "is going to leave" instead of "is leaving."
Report it !
"Otobüs dörtte kalkacak."
Translation: The bus will depart at four.
The bus will leave at four. - Wrong.
