if vs when (Are aeroplanes cancelled when it rains?)

[Daemon99]

I want to ask if the aeroplanes would be cancelled due to rain. Are the following sentences OK for it?

1) Are aeroplanes cancelled if it rains?
2) Are aeroplanes cancelled when it rains?
3) Would aeroplanes be cancelled if it rained?

Can I use flight in place of aeroplane? What's the common word for aeroplane?

Hi Daemon,

All three sentences are fine accepting that 'if' refers to condition and 'when' refers to time. I use the word 'plane'. 'Flight' refers to the process of flying and is often used in connection with a code and number of a particular journey by plane as in: Pasengers for Flight No. XZR 234 are asked to make their way to gate 4.
