Yeah but you won't actually fly 720 sectors a year.... so the sector pay in my previous calc is vastly exaggerated. Lets go for the industry standard in loco of about 450 sectors a year.
So he'll make 44100 basic
450x 60 = 27000 sector
71100 a year = 5925 a month before tax.
Cut the BS, either no tax is being paid or ur friend is overstating his take-home (which happens quite a bit with pilots I have noticed)
