What procedure should be followed for communication issues with the tower while landing?

When encountering communication issues with the control tower while landing, the proper procedure is to notify the tower of your intention to land and request light signals. This is crucial because when an aircraft cannot communicate effectively via radio, the use of visual light signals allows the tower to provide necessary instructions or advisories to the pilot. Light signals can convey important information about whether to continue the approach, go around, or perform other maneuvers safely.

Following this protocol ensures that the pilot remains aware of the tower's instructions despite the communication breakdown. It also maintains safety by following established procedures for such situations, which is vital in busy airspace environments.

In this context, simply entering Class D airspace and waiting for clearance does not address the immediate need for instructions during a critical phase of flight. Attempting to communicate with other aircraft could lead to confusion and is not a reliable way to receive necessary instructions from the tower. Lastly, proceeding directly to approach without communication does not prioritize safety and could lead to dangerous situations, including mid-air collisions or improper landings. Thus, requesting light signals after notifying the tower is the most prudent action to take.
