PLT312: Load Factor
What code PLT312 covers, why the FAA tests it, and how to study Load Factor before your checkride.
Recall load factor - maneuvering / stall speed
What this means for your checkride
Load factor and stall speed are linked: any maneuver that raises load factor also raises the speed at which the wing stalls. Maneuvering speed (Va) is the fastest speed at which a full control input or a strong gust will stall the wing before it can overstress the structure, and it decreases as weight decreases.
This connection is what keeps a pilot safe in turbulence and abrupt maneuvers, so the FAA tests how load factor raises stall speed and why you slow to maneuvering speed in rough air.
Pilots think maneuvering speed is a single fixed number. Va is lower at lighter weights, so a light airplane must slow down more in turbulence than the full-gross figure suggests to keep the same protection.
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.
