March 16, 2018, ©. Leeham News: In the last Corner, we looked at the drag of an airliner during cruise. We could see the thrust required to counter the drag in the thin air of 37,000 feet was low, about 4,000lbf per engine. Now we continue with the drag created by the aircraft during descent and landing. We are assuming our aircraft is the A320neo type with a cabin with 180 seats, all filled with passengers.
