Final answer:
The left turning tendency in an airplane climb is overcome by banking the aircraft. The increased lift on the wing during the bank counteracts the left turning tendency and allows the airplane to maintain a straight flight path while climbing.
Step-by-step explanation:
In an airplane climb, the left turning tendency is overcome by banking the aircraft. When an airplane banks, the pilot increases the lift on the wings, which causes a horizontal component of lift to act towards the inside of the turn and counteract the left turning tendency. This allows the airplane to maintain a straight flight path while climbing.
For example, if the airplane is climbing to the right, the pilot will bank the aircraft to the right. This increases the lift on the right wing, creating a horizontal component of lift to the right that counters the left turning tendency caused by the climbing motion.
