There are times when the pilots need to look outside. It is still safer to do this with windows instead of using cameras that can fail.
Airplane windows need to be open during takeoff and landing to allow passengers to see outside and help maintain orientation in case of an emergency evacuation.
Aircraft windows need to resist severe air pressure changes and pressure differential.
The correct term for an airplane window is a porthole, the same as for a window on the side of a ship.

Why are airplane windows curved? A: This Q is about windows that are NOT flat. Usually curved windows are designed to fit the shape of the airplane so as make the airplane more aerodynamic and not be boxy. Why are airplane windows rounded on the corners? A: One of the first British jets began to crash for no reason. This airplane, the Comet, had large square windows. The investigation discovered that the airplane cracked open at the corners of the windows. This was about the time that engineers began to understand the phenomna of Fatigue. Their tests showed that the corners of the windows resulted in higher stresses and it fatigued the metal. They redeisgned the windows to be rounded and it reduced the stresses and no more planes crashed. Sharp corners in holes of any surface that is carrying a load will increase the stresses. If the corner is changed to a curved edge, then the stresses are lowered. Think of stress as a flow of forces and when it comes to a sharp corner, the flow can't go around the corner.
Airplane windows need to be open during takeoff to allow passengers to see outside and help maintain a sense of orientation and balance. This can reduce feelings of motion sickness and anxiety during the ascent. Additionally, having windows open can provide natural light and ventilation in the cabin.
The windshield, the windows? Lol
Reinforced glass.
Windows have to be up for takeoff on an airplane to ensure visibility and communication between passengers and crew, as well as for safety reasons in case of emergencies.
You can't open them to begin with. Most airline windows have a shade that can be pulled down.
To keep the temperature inside the airplane nice.
