A pilot's receiver and transmitter are both inoperative. What does the PHAK say about a towered airport with Class D airspace?

  1. Enter the pattern at once and land without waiting for light signals
  2. Circle over the field below the pattern altitude until a signal comes
  3. Divert to an uncontrolled airport with less traffic, and land there
  4. Stay outside Class D until the traffic flow is known
Show answer

Correct answer: Stay outside Class D until the traffic flow is known

With both radios failed, stay outside Class D until the traffic flow is known. Then enter the pattern.
