Thanks, interesting and good suggestions.
When someone points something out, I always remain open to their comments/remarks/suggestions and observations.
I firmly believe good CRM is not simply what you say, but HOW you say it.
Had they questioned "Is your AS getting low" I would have responded, "No, it's fine, power is correct and we're properly trimmed out" But the way he barked at me, I actually jumped slightly and was totally unnerved by his manner.
I should have said above, that at the end of the flight I said "Things didn't go to well today, can we have a chat when we park up please" to which they responded "Little wonder with flying like that"
I've been chewing over this one and discussed with a few other pilots, apparently this chap is a bit of an egoist and I'm not the first to have experienced his antics so if we fly again I will be having a very long chat before we go near the aircraft.
