IFR Quiz #3

There are at least 2 ways to practice this quiz. One way is to check your answer by clicking the "Check answer" button. This will give you immediate feedback regarding specific questions. The other option is to simply answer all the questions as a test and "Flip the switch" or "Press the button" (grade the test) after the last question to receive a test score. You can then check each question individually to see which questions were missed. If you have any problems or suspect an error, feel free to contact me anytime.

Thank you and good luck.

1. When simultaneous ILS approaches are in progress, which of the following should approach control be advised of immediately?

Any inoperative or malfunctioning aircraft receivers.
