Basically he climbs with max climb thrust at as fast a speed as possible. I have clocked him at 52 minutes to climb to cruise in an aircraft that can climb to that cruise alt in 20 to 25 comfortably at the weight we were. He says that the money spend on fuel is made up for by getting there faster. Today he said we should refuel full so we can save money as its cheaper where we are but he will climb out in the same way.. He actually would fill up full everytime he could no matter where we are or what it costs if he was not monitored. He is a nice guy but I just cant seem to get through to him.
