PLT469: Airborne Weather Radar
What code PLT469 covers, why the FAA tests it, and how to study Airborne Weather Radar before your checkride.
Recall regulations - weather radar
What this means for your checkride
Certain air-carrier airplanes must have approved airborne weather radar, and the pilot must not begin a flight into areas of forecast or observed thunderstorms or hazardous weather when the radar is inoperative. When it is operating, it is used to avoid detected areas of severe weather.
Thunderstorm penetration is deadly, so the FAA tests when weather radar is required and the operating limitations tied to its condition.
An inoperative weather radar does not simply mean fly with caution; it prohibits dispatch or continuation into areas of known or forecast hazardous thunderstorm activity.
Where to study it
A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
