Answer:
Based on the information provided, the correct answer is:
b) Lift-to-Drag Ratio
Explanation:
The lift-to-drag ratio is a measure of the efficiency of an aircraft in generating lift compared to the amount of drag it experiences. In this scenario, when the aircraft is in a power-on, 60° bank with gear and flaps up, the lift-to-drag ratio is 10 knots higher compared to when the gear and flaps are down.
When an aircraft is in a banked turn, the lift force is partially redirected to maintain the aircraft's path. This redirection of lift creates an increase in drag. Additionally, when the gear and flaps are up, the aircraft's drag is reduced, leading to a higher lift-to-drag ratio.
It is important to note that the lift-to-drag ratio is a critical factor in determining the aircraft's performance, specifically in terms of its efficiency and speed. By optimizing the lift-to-drag ratio, pilots can achieve better fuel efficiency and higher speeds.
Therefore, based on the given information, the most appropriate answer is b) Lift-to-Drag Ratio.
