Trivia of the Day

Test your Knowledge

Trivia rolls over daily at midnight, Mountain Standard Time.

Private Pilot Question of the Day


Which list identifies the categories in §21.175(a)(1) for standard airworthiness certificates, and how must a pilot operate within the aircraft’s approval?

Commercial Pilot Question of the Day


During a daytime VFR flight in a piston airplane, verified engine fuel consumption in gallons per hour has remained 15 percent above the planning rate at the same power setting. Recalculation using that observed rate predicts arrival with only the regulatory reserve and no allowance for further delay. A suitable fuel stop is available now with ample margin. Which assessment and decision best address the continuing discrepancy?

Instrument Rating Question of the Day


What does a serrated ARTCC boundary line on an FAA IFR en route chart identify?

FAA Aeronautical Chart User's Guide (effective July 9, 2026).

Sport Pilot Question of the Day


What avoidance responsibilities should a nonparticipating pilot apply near active parachute operations?

Flight Instructor Question of the Day


Which trend most strongly indicates that useful thermal conditions may be developing into a serious convective hazard?

Flight Instructor Instrument Question of the Day


In the remarks section of a METAR, what does RAE42SNB42 mean?

Small Unmanned Aircraft Systems Question of the Day


Why must a remote pilot apply both regulatory and aircraft-specific operating limitations before launch?

Advice of the Day

System of the Day


Cabin Heating and Cooling Systems: Cabin Heating and cooling systems provide conditioned air for comfortable operations during various weather conditions



Maneuver of the Day


Unusual Attitudes: Unusual attitude recoveries teach pilots to understand the human system's susceptibility to spatial disorientation and how to recover if required.

Emergency of the Day


Engine Failure: The total loss of power requires immediate actions which depend upon speed (life) and altitude (life insurance)



Mishap of the Day


ERA14LA450: The NTSB determines the probable cause(s) of this accident to be: The pilot's inadequate preflight planning, which resulted in a takeoff with the airplane's center of gravity aft of its limit and led the airplane to exceed its critical angle of attack and experience an aerodynamic stall during the initial climb.



Regulation of the Day
