This long break in flying for many is a real risk that must not be underestimated. I suspect it has been a factor in many incidents and the odd accident already. Complacency from crew not showing this threat the respect that it deserves will be an issue.
Regardless of experience or being a sky god in an earlier life, those not appreciating the risks will easily fast come unstuck. Mental capacity, flying skills, work rate, situation awareness, decision making, will all be detrimentally affected. For those that have not operated for extended months at a time, now is not the time to take any extra risks whatsoever. It's time to refresh, go through the manuals, checklists and procedures, do the currency sims. Then take things easy, not rush, ignore time pressures as best as possible. The sims might be the easiest part, but then the greatest risks will present back online. Slow the operation down, no rushed approaches, checklists or briefings, turn down the crazy shortcuts to final throwing the barn doors out and the unnecessary raw data visuals. Use the automatics, leave behind the bravado and keep the threats in mind. The operation needs to be kept totally standard, not rushed, with the sole purpose of no reports or incidents, at lowest risk possible. Get back into the swing of things before the 'click click Seneca mode'. Don't be the one that gets caught out, and recognise it could be us the very next time, by truly believing that it is possible in a flash without warning.
No pilot on this planet given the extended breaks in operating will be safe from the threats that this represents without careful management.
