Multiple choice

In case of the failure of static source, what is recommended action to be taken?

  1. Turn the battery off.

  2. Break the glass of VSI.

  3. Restart the magnetos.

  4. Squawk 7600 on Mode C.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When the static source fails, breaking the glass of the VSI (Vertical Speed Indicator) provides an alternate static source because the VSI case is connected to the static system. This is a standard emergency procedure in many aircraft. The other options are irrelevant - turning off the battery, restarting magnetos, or squawking 7600 (radio failure code) do not address static system failure.
