PLT506: V-Speeds And Arc Markings
What code PLT506 covers, why the FAA tests it, and how to study V-Speeds And Arc Markings before your checkride.
Recall V speeds - maneuvering / flap extended / gear extended / V1, V2, r, ne, mo, mc, mg, etc
What this means for your checkride
Airspeed indicator markings define key V-speeds. The upper limit of the white arc is VFE, the maximum speed with the flaps extended. VLE is the maximum speed at which the aircraft may be flown with the landing gear extended. Operating above these limits can damage the extended flaps or gear.
Pilots must respect configuration speed limits to avoid structural damage, so the meaning of each V-speed and arc is tested.
Students sometimes confuse VFE with VLE; VFE limits flap-extended speed while VLE limits gear-extended speed.
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.
