The magnetic compass works without electricity but produces predictable errors during acceleration and turns - here's how to correct them and pass your partial panel checkride.
PatternVOR navigation remains essential in the GPS era - knowing how to read a CDI needle correctly is what separates prepared IFR pilots from those chasing a magenta line that no longer works.
TowerSynthetic vision technology renders a real-time 3D terrain picture on your PFD using GPS, AHRS, and terrain database data - and carries a critical limitation every pilot must know.
VectorVacuum pump failure in IMC is silent and deceptive - your attitude indicator will keep lying for up to three minutes. Here's how to catch it early and fly to safety.
PatternA wrong altitude readback slipped past both pilot and controller on an IFR flight, nearly ending in Controlled Flight Into Terrain - stopped only by an onboard terrain alert.
TowerThe Garmin GI 275 replaces vacuum-driven attitude indicators with solid-state ADAHRS technology, eliminating a proven fatal failure mode for under $6,000 in hardware.
VectorSynthetic vision technology gives instrument pilots a continuous 3D terrain picture generated in real time from GPS and elevation data, dramatically reducing CFIT accidents in general aviation.
VectorThe FAA has launched a public webform for pilots to report inaccurate or malfunctioning AWOS and ASOS weather sensors, creating a centralized feedback loop for surface observation data.
TowerWhen ATC issues 'climb and maintain' on a SID, altitude crossing restrictions are cancelled - a critical distinction every IFR pilot must get right.
TowerA symbol-by-symbol breakdown of the most misread markings on instrument approach charts, from the Final Approach Fix to DME arcs.
TowerWAAS delivers precision approach capability to over 4,000 U.S. airports through satellite-based corrections and integrity monitoring, without any ground equipment at the airport.
VectorThe Current Icing Product (CIP) maps structural icing probability by altitude layer every hour using multi-sensor data fusion - and it's free at aviationweather.gov.
VectorOn September 24, 1929, Jimmy Doolittle flew the first fully instrument-guided flight in history - the 15-minute test that made modern IFR flying possible.
TaildraggerWAAS delivers ILS-equivalent precision guidance to over 4,000 U.S. airports using satellite-based error correction - here's how it works and what it means for IFR pilots.
VectorHarold Gillam was Alaska's most feared bad-weather pilot - until a January 1943 mountain in southeastern Alaska ended his legendary career and stranded five survivors for 32 days.
TaildraggerA fly visual segment marks where published instrument guidance intentionally ends mid-approach - what every IFR pilot must understand before briefing one.
TowerThe Jeppesen 10-9 airport page consolidates takeoff minimums, alternate requirements, hot spots, and runway data that FAA chart users find spread across multiple documents.
TowerOn September 24, 1929, Jimmy Doolittle completed the first fully blind flight at Mitchel Field, NY, proving instrument flying was a reproducible skill - not a gamble.
TaildraggerBefore every IFR departure, verify your aircraft can meet the published ODP climb gradient - a performance requirement buried in procedure notes that many pilots overlook.
TowerTuning into ATIS mid-broadcast means pilots routinely miss the NOTAM section - a structural problem AOPA highlighted in its September 2026 safety series.
