So how will you fly the aircraft during ramadan if you are unable to concentrate?
I have many muslim friends who are good pilots and fasting during Ramadan has not been an issue for them where aviation safety is concerned. If they are not able to fast for health or safety concerns they may go for the option of breaking the fast and make up for it another day. But of course it is up to them to decide for themselves..At least that's how I understand it to be..
