WebDec 24, 1999 · Lift does not make an aircraft climb. Excess thrust is responsible. During a climb the vertical component of lift opposes the directrion of flight working to slow the aitcraft. The thrust vector is pointed downward causing the aircraft to climb. Every transport category aircraft uses flaps to climb. Usually 10 -15 degrees on TO. WebAs Fowler flaps extend more and more, they move more in a downward motion to create a little more lift, but a lot more drag, which is useful in many circumstances. They are similar to slotted flaps except they can extend both down and back. Many aircraft, including the P-47d Thunderbolt, use Fowler flaps. 5.
