Rushed take-off?
I want to open a thread about something I've noticed on the last few short-haul flights I've taken. I'm not sure if this is an issue or not (I'm sure I'll soon be told if it isn't!).
I've noticed that some pilots on short-haul flights "rev" (sorry - don't know the technical term) the engines to check they're stable literally as they are still turning onto the runway and before they are lined up.
Is this a common and accepted practice? Do any professional pilots frown upon it? (For example, if it caused you to mess up your alignment.) Is it at all a sympton of a rushed take-off?
I'd appreciate your comments.
