How will an approach without the use of flaps typically behave?

When an approach is made without the use of flaps, it will generally behave faster and shallower compared to an approach that includes flap extension. Flaps are designed to increase the lift produced by the wings at lower speeds, allowing the aircraft to operate safely at a slower airspeed during landing. Without flaps, the aircraft requires a higher airspeed to maintain controlled flight, resulting in a faster approach.

Additionally, the lack of flaps reduces the lift, making it necessary to approach the runway at a more horizontal or "shallower" angle. This can impact the aircraft's landing configuration, requiring the pilot to maintain a more precise airspeed and angle to avoid the risk of landing short or overshooting the runway.

In summary, flying without flaps results in a faster approach speed that requires careful management to control the descent path, thereby making the approach shallower. Understanding this dynamic is crucial for pilots to manage their descent and landing effectively.
