increase the angle of descent without increasing the airspeed.
The flaps help to increase lift, which is essential to the landing and takeoff phase[s].
Airplane wings are designed to be most efficient when at high altitudes, traveling fast, while providing as little drag as possible. Unfortunately this design inst the best for takeoff and landing. Flaps are used to change the shape of the wing to accommodate takeoff and landing requirements. Most planes have flaps on the front of the wings (leading edge flaps) and at the back of the wings. During takeoff flaps increase lift so a plane can take off with limited runway length and lower speeds. As the plane gains speed the flaps are retracted. On approach and landing you want to fly as slow as possible so the flaps are deployed in increments till landing speed is achieved. Landing slower means less runway needed to stop.
on an ils speeds set a landing speed would be around 145kts-150kts (166mph-172mph) depending on the landing flap setting selected - this is based on full flaps
Approach speed depends on the plane, the load, and the wind. You can go full flaps on a Cessna 150 and land at about 50 mph (stall speed). If you are landing into a 30 mph headwind, you land at about 20 mph.
Flaps generally change the geometry of the wing for landing and take off speeds
No. On MOST airplanes, ailerons are separate from flaps. Ailerons are used to help steer the airplane, while flaps are lowered to change the aerodynamic shape of the wing to provide more lift during take off and landing.

Flaps and stats increase lift for takeoff and slow you down, for landing.
Yes, Flaps are both used to create lift (on takeoff) and to slow the aircraft (on Landing)
Flaps are the devices that extend off the back of the wing. They are used for take off as well as landing. They increase lift and reduce the speed at which airflow over the wing is disrupted, thereby resulting in a slower approach and landing speed.
It's not tested. Aircraft always are requried to land with full flaps. Having been through a flaps up landing on a brand new 737-800, I seem to remember that the pilot said that we landed at around 180 knots. One of the computers malfunctioned and did not let the pilot engage the flaps.
An aircraft flap is simply called a "flap." Flaps are movable surfaces located on the wings of an aircraft. They are designed to change the shape and configuration of the wing during different phases of flight. By extending or retracting the flaps, pilots can adjust the lift and drag characteristics of the aircraft, allowing for changes in speed, angle of descent, and takeoff and landing capabilities. Flaps can be divided into several types, including: Plain Flaps: These are the simplest type of flaps, which extend straight down from the wing when deployed. Split Flaps: These flaps are divided into two sections, with the lower section extending downward and the upper section remaining in place. Slotted Flaps: Slotted flaps have a slot or gap between the wing and the flap, which helps to increase lift at lower speeds. Fowler Flaps: Fowler flaps extend backward and downward, increasing both the wing area and camber, which allows for greater lift generation. The specific type of flap used on an aircraft depends on its design and intended purpose. Flaps play a crucial role in controlling and maneuvering an aircraft, particularly during takeoff and landing.
