At AI the FO's are, at best, given 3-5 take offs and landings a year. Some a lot more, others even less. The omniscient "Commander" will more than likely take all sectors. I do know that expat Capts will be more willing to "give flying" to the FO as that is what they are accustomed to do. The local guys are "accustomed" to a different ideology.
So, when the FO becomes a "Commander" he / she will behave the same way, ie following the "custom" & airline culture that they were bought up in to do all the flying. That is not their fault as they have been treated this way and hence belive "it is the way it should be".
Recency on t/o's & landings, let alone approaches? All waivered and / or covered up by the fraudulent proficiency checks and sims.
So, blame the pilot or blame the system?
