Uplinker,
There is no need to get into a state of piloerection. All I am saying is, the cabin crew input has to be timely, the information has to be factually credible.
I have been flying commercial jets for 30 years and more than 20 years in command, if a wing needs to be inspected before lining up for takeoff, I would trust the copilot or the augmenting pilots to do it instead of the cabin crew.
By the way, my crew can place a call that has different level urgency to me. It would display as ‘CABIN ALERT’ or just a usual ‘ CABIN CALL’.
Merry Christmas and Happy New Year!
