When is communication required before landing at an airport with an operating control tower in Class E airspace?

When operating in Class E airspace with an airport that has an active control tower, it is essential to communicate your intentions to the tower before landing. The correct answer indicates that this communication is required at a distance of 4 nautical miles from the airport and up to and including 2,500 feet above ground level (AGL). This requirement is in place to ensure that all aircraft are coordinated and safely managed as they approach the airport, thereby preventing potential conflicts and enhancing safety during the landing phase.

Clear communication with the control tower helps controllers manage air traffic effectively, allowing them to provide instructions or crucial information to pilots about other aircraft in the vicinity or changes related to weather conditions. By adhering to this regulation, pilots improve situational awareness and contribute to a safer operating environment in controlled airspace.
