RHS at Jet2 is what you make of it. If you sit there day in day out with your thumb up your behind just cruising along, you'll obviously struggle come time for upgrade.
I'm staggered by how often it's commented that I'm doing things other FOs don't do. All I'm doing is my job to the best of my ability!
If you put the effort in to learn your job and some of what the LHS is doing, you take ownership of your development. It then lessens the load when facing command as you'll already be familiar and comfortable. I'm talking about running your sector as PF from briefing the crew /dispatcher, completing the tech log for the skipper, liaising with ops, welcome PA, etc. Obviously you pick the time and place as there are those who are more receptive to this than others...
You may read this and think seriously, completing the tech log is a big deal? Well I'm firmly in the belief of taking care of the little things so the big things take care of themselves.
