Final answer:
Position 1 on the FLAPS lever corresponds to a TAKEOFF configuration, where both the flaps and slats are extended to improve lift and control during takeoff.
Step-by-step explanation:
Position 1 on the FLAPS lever typically corresponds to a TAKEOFF configuration. In this configuration, the flaps and slats are extended to improve lift and provide better control during takeoff. The exact flap/slat configurations can vary depending on the aircraft, but generally, the flaps are extended to a moderate position (usually around 10-20 degrees) and the slats are extended to a lesser extent (usually around 5-10 degrees). The purpose of the flaps and slats is to increase the surface area of the wing, which generates more lift at lower speeds.
