Absolutely unbelievable. Here's how you send the wrong message to your pilots, as a manager or supervisor.
"So, you consulted the AFM and determined that a departure could be unsafe? That's a misinterpretation of the AFM and despite the fact that you "erred" toward caution, I'm suspending you and pending review, you may be fired."
This kind of nonsense strengthens my desire to be involved in the safety department. You can't just tell people to be safe. You have to reinforce safe behavior. This is negative reinforcement, am I right?
