The frustration comes from, and from what a lot of experienced FO's, SFO's and Capts repeat on here and socially all the time, is that all too often it becomes a single pilot operation in sims or other flight events when the SO due lack of genuine experience hasn't a clue
Those S/O's are now JFO's and things are getting real interesting.
Had to help a guy out the other day with his PM duties, so yes, single pilot ops it is.
The return PF sector was even more exciting!
