PLT524: Electronic Flight Display (PFD)
What code PLT524 covers, why the FAA tests it, and how to study Electronic Flight Display (PFD) before your checkride.
Interpret / Program information on an avionics display
What this means for your checkride
An Electronic Flight Display, or glass cockpit, presents the traditional six-pack of instruments on one screen called the primary flight display (PFD). Airspeed appears as a vertical tape on the left with color-coded ranges and reference bugs for speeds like VX, VY, and rotation, while attitude, altitude, vertical speed, and heading are arranged around the display. You interpret the moving tapes and reference marks the same way you would read the analog gauges they replace.
Reading and setting values on a PFD is essential as glass cockpits replace analog panels in modern aircraft.
Fixating on the digital numbers rather than the tape trend, which can slow recognition of a developing airspeed or altitude change.
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.
