PLT405: Instrument, Equipment, and Certificate Requirements
What code PLT405 covers, why the FAA tests it, and how to study Instrument, Equipment, and Certificate Requirements before your checkride.
Recall regulations - equipment / instrument / certificate requirements
What this means for your checkride
A powered civil aircraft with a standard U.S. airworthiness certificate may not be operated unless it contains the instruments and equipment specified for that type of operation, in operable condition; for example, VFR day flight requires an airspeed indicator, altimeter, and magnetic direction indicator, among others. Separately, no civil aircraft may be operated unless it carries an appropriate and current airworthiness certificate and its registration.
It links the aircraft's required equipment to the kind of flight and confirms the documents that must be aboard.
The required equipment depends on the operation, so VFR day, VFR night, and IFR each add items rather than sharing one fixed list.
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.
