No it's not harsh. Some of the comments on here are stunning. Climbing in a heavy jet aircraft at high altitude in V/S instead of Managed... and yet you see it on the line frequently enough. Who's training them? When the engines are at limit thrust and IAS begins to creep back while the guy winds in a higher RoC it's time to select it for him.
It's not only this V/S thing; there seems to be a lot of airmanship/common sense
fundamentals missing in this airline which is amazing considering the background (previously) required to get in. Maybe if the instructors talk about these concepts they are accused of teaching "technique."
Did you mean Angle of Attack? If so, getting the terminology correct might be a good start. Or are you trying to say a constant body angle is the way to do it??? Open Descent for a 1000ft descent into London is hardly going to be enough time for the aircraft to "wander thru the sky with large (or "wild") V/S variations." Sorry but it sounds like you have no idea what you're talking about.
People who don't know how their cabin altitude management works...
Also scary that some pilots fly for hours thinking their engines might blow at any moment. Must be a nervous time on those ULRs.
