I encountered the dirty sock smell recently, pretty strong on takeoff roll and the first 5 min of the climb then it went away.

FWIW, it was the first flight after oil was added to the engines so I’m not sure if some oil was spilled somewhere or if excess oil vented or if that was even related. Same plane had no smell on the next leg

I agree, we need a little more guidance for this scenario, I feel like we could be asked “why the heck did you do that?” No matter which course of action we take (or don’t take).

That letter is a must read
