The force of social conditioning that prevents a FO from taking control (Gear/Toga/ATC call out) in 2020 is beyond words
well actually it may not be that. Why would he take control if it's common occurrence? There's enough evidence that hot and high approaches is common occurrence may be it's considered macho to do so. Then why would the FO prove that he is less by taking over?
Secondly on local media serious training issues are raised where pilots are able to arrange their PPCs according to their choice. The FO has to be competante enough to be confident to do such an act.
