An airport installation is composed of several components, including RADAR, SPA, ORD, PANE, and windsock. RADAR is a system that uses radio waves to detect the presence of objects, such as aircraft, and is used to monitor air traffic. SPA stands for Standardized Portable Airport, which is a type of portable runway that can be quickly set up in emergency situations. ORD stands for O'Hare International Airport, which is one of the busiest airports in the world. PANE stands for Precision Approach Path Indicator, which is a visual aid used to help pilots land their aircraft safely. Finally, a windsock is a conical fabric tube that is used to indicate wind direction and speed.
