PLT370: ATC Clearances and Instructions
What code PLT370 covers, why the FAA tests it, and how to study ATC Clearances and Instructions before your checkride.
Recall regulations - Air Traffic Control authorization / clearances
What this means for your checkride
Once an ATC clearance is obtained, the pilot in command may not deviate from it unless an amended clearance is obtained, an emergency exists, or the deviation responds to a TCAS resolution advisory. Except in an emergency, no person may operate contrary to an ATC instruction where air traffic control is exercised. When uncertain of a clearance, the pilot must immediately request clarification from ATC.
Following clearances exactly, and knowing the narrow exceptions, is central to safe operation in controlled airspace.
Some pilots think a clearance is a suggestion; it is binding unless amended, an emergency exists, or a TCAS RA requires the deviation.
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.
