I don’t know how you can argue that one Ollie.
More time to peruse the proposed flight as per the CARs is always better than less.
The preflight briefing is to discuss what information will affect your flight and to discuss fuel as a crew. It’s not really to digest the proposed flight. It just means you have less time to discuss it if you’re still digesting it.
We are paid to run a schedule. From A-B on time. That is the whole basis of RPT. That’s what an airline does. For our valued business clients in the premium side of the business it’s critical (obviously I don’t fly the Jetstar line).
I personally do a lot of study in my home time. There’s 3 stages you go through as an aviator.
learning to fly
consolidating existing knowledge
Actively seeking new knowledge
Be the third one. Especially if you’re a captain.
