Questions & Answers about Kontroler koordynuje manewry, podczas gdy samoloty lądują.
Could I just say podczas samoloty lądują?
No. Podczas is a preposition meaning "during" and must be followed by a noun, usually in the genitive case (for example, podczas lądowania - during the landing). Because we have a full clause here with its own subject and verb (samoloty lądują), you must use the conjunction podczas gdy (while).
Notice how both verbs (koordynuje and lądują) are imperfective. Is this expected with podczas gdy?
Yes, when podczas gdy is used in a temporal sense to mean "while", it typically connects two ongoing, simultaneous actions. Because the actions are continuous and happening at the same time, imperfective verbs are the natural choice for both parts of the sentence.
Manewry and samoloty both end in -y. Are they in the same case?
They look identical but are in different cases! Samoloty is the subject of the second clause, so it is in the nominative case. Manewry is the direct object of koordynuje, so it is in the accusative case. For plural inanimate nouns, the nominative and accusative forms are exactly the same.
Do I always need a comma before podczas gdy?
