Avionics / MFD Display Failure in Night VFR
FAA Ref: FAA-S-ACS-6C Area IX Task C (Systems and Equipment Malfunctions)
Scenario & Physics Summary
Immediate transition to standby mechanical instruments, paper/tablet backup, VOR/NDB raw data, and pilotage at night.

Aerodynamic & Operational Physics
- Glass cockpit Primary Flight Display (PFD) or MFD screen blackouts remove artificial horizon, moving map, and digital engine gauges simultaneously.
- Relying solely on GPS without maintaining paper chart log or VOR raw fixes creates spatial disorientation when screens fail.
- Maintain attitude using standby attitude indicator/turn coordinator, scan outside visual cues (ground light clusters), maintain altitude, notify ATC.
FAA Exam Gotcha Alert
FAA Exam Trap: Night VFR regulations require candidates to maintain dead reckoning logs regardless of GPS installation status.
Frequently Asked Questions & Exam Explanations
What is the primary risk when GPS screens go dark at night?
Pilot spatial disorientation due to sudden loss of visual horizon and situational awareness.
