Core Knowledge Areas

Essential aviation fundamentals every pilot must master — from aerodynamics to airspace classification.

Aerodynamics

Lift, drag, thrust, and weight — the four forces of flight. Understand how wings generate lift and how aircraft stay stable.

Aviation Weather

METAR/TAF decoding, pressure systems, cloud types, icing conditions, turbulence, and weather-related hazards.

Navigation

VOR, NDB, GPS, and RNAV — pilotage, dead reckoning, and modern area navigation concepts.

Airspace

Classes A through G, special use airspace, TFRs, and requirements for each — visibility, cloud clearance, and communication.

§

Regulations

Part 91 essentials — currency requirements, fuel minimums, right-of-way rules, equipment requirements.

Performance

Weight and balance, density altitude, takeoff/landing distances, and aircraft performance charts.

Flight Instruments

The primary flight instruments every pilot scans. Click any instrument to learn more.

ATTITUDE
AIRSPEED
ALTIMETER
HEADING
VERT SPEED
TURN COORD
Pitot-Static System: The Airspeed Indicator, Altimeter, and VSI all rely on the pitot-static system. A blocked pitot tube or static port can cause erroneous readings — a critical emergency awareness item.
Gyroscopic Instruments: The Attitude Indicator, Heading Indicator, and Turn Coordinator are gyro-driven. Vacuum pump failure will cause the AI and HI to fail — always cross-check with the magnetic compass and turn coordinator.
Radio & Phraseology

Master the language of aviation — proper phraseology keeps everyone safe.

Click any letter to hear it spoken. The NATO phonetic alphabet is standard worldwide.

121.500 MHz

Emergency — International distress frequency. Guard at all times. Use for MAYDAY and PAN-PAN calls.

122.800 MHz

UNICOM — Uncontrolled field advisory. Self-announce position and intentions at non-towered airports.

122.000 MHz

Flight Service — FSS en-route frequency for weather updates, PIREPs, flight plan operations.

122.750 MHz

Air-to-Air — Pilot-to-pilot communication for coordination during formation flight or search operations.

122.200 MHz

Flight Watch — En Route Flight Advisory Service (EFAS) for real-time weather along your route below FL180.

243.000 MHz

Military Emergency — UHF military guard frequency. Monitored by all military and many civilian facilities.

FREQ 118.700 — KORD APPROACH
Remember: WHO you're calling — WHO you are — WHERE you are — WHAT you want. That's the template for every initial call.
MAYDAY (Life-threatening)
"Mayday, Mayday, Mayday. [Facility], [Callsign], [Type Aircraft], [Position], [Altitude], [Nature of Emergency], [Intentions], [Souls on Board], [Fuel Remaining]"
PAN-PAN (Urgent, not life-threatening)
"Pan-Pan, Pan-Pan, Pan-Pan. [Facility], [Callsign], [Nature of Urgency], [Pilot Intentions], [Position], [Altitude]"
POSITION REPORT
"[Facility], [Callsign], [Position], [Altitude], [Estimating next fix at time], [Following fix]"
UNABLE / WILCO / ROGER
Roger = received. Wilco = will comply (includes roger). Unable = cannot comply. Affirm = yes. Negative = no.
Guides & Tutorials

Guided walkthroughs for fundamental aviation procedures and concepts.

Weather Briefing

Contact 1-800-WX-BRIEF or use ForeFlight/1800wxbrief.com. Get a standard briefing covering: adverse conditions, synopsis, current/forecast weather, winds aloft, NOTAMs, and TFRs.

Always check NOTAMs — temporary flight restrictions for VIP movement, airshows, or emergencies can pop up anywhere.

Weight & Balance

Calculate total weight and CG position. Verify within the aircraft's envelope. Overweight or out-of-CG aircraft have degraded performance and handling.

Performance Calculations

Using current conditions (temperature, pressure altitude, wind), compute takeoff distance, climb rate, and landing distance. Add safety margins.

Density altitude kills. On hot, high, humid days, your aircraft performs as if it's thousands of feet higher.

File Flight Plan

VFR or IFR — file via ForeFlight, Leidos, or ATC. Include route, altitude, fuel endurance, and alternates. Activate once airborne.

Walk-Around Inspection

Follow the POH checklist methodically. Check control surfaces, fuel quantity/quality (drain sumps), oil, tires, pitot tube, static ports, lights, and antennas.

✓ IMSAFE Checklist (Pilot)

Illness — Am I feeling well?
Medication — Am I on any drugs that impair?
Stress — Am I under unusual stress?
Alcohol — 8 hrs bottle-to-throttle, <0.04 BAC
Fatigue — Am I well-rested?
Emotion — Am I emotionally fit to fly?

✓ PAVE Checklist (Risk)

Pilot — Experience, currency, fitness
Aircraft — Performance, equipment, fuel
enVironment — Weather, terrain, airspace
External Pressures — Schedule, passengers
Get-there-itis is the #1 killer of GA pilots. Always maintain personal minimums and be willing to cancel or divert. No flight is worth your life.

The standard traffic pattern is a rectangular ground track flown at a specific altitude (typically 1,000 ft AGL). All turns are made to the left unless otherwise specified by the airport's traffic pattern indicators.

RUNWAY 27 UPWIND CROSSWIND DOWNWIND BASE FINAL TPA: 1,000 ft AGL WIND ←

Upwind

After takeoff, climb straight out along the runway heading to pattern altitude.

Crosswind

Turn 90° left. Begin when within 300 ft of TPA or at the departure end of runway.

Downwind

Fly parallel to runway, opposite direction. Abeam the numbers: reduce power, begin descent.

Base

Turn 90° left. Continue descent, configure flaps. Watch for traffic on final.

Final

Turn to align with runway. Stabilized approach — on speed, on glidepath. Full flaps.

Aviate, Navigate, Communicate. Always in that order. Fly the airplane first. Never let comms or navigation distract from maintaining control.

Engine Failure — Takeoff

Below Vc: Land straight ahead. Do not turn back (the "impossible turn" kills pilots). Adjust heading for obstacles.

Above Vc and sufficient altitude: Consider return to field only if you have altitude, airspeed, and have practiced the maneuver.

Engine Failure — Cruise

Best glide speed immediately. Pitch for Vg (in POH). You have time. Restart checklist: fuel selector, mixture, mags, carb heat. Pick a field, set up pattern, SQUAWK 7700, declare on 121.5.

Electrical Fire

Master switch OFF, all avionics OFF, cabin heat OFF, vents OPEN. If fire extinguishes: selectively re-enable circuits to isolate the fault. Land at nearest suitable airport.

Vacuum Failure

Attitude indicator and heading indicator will slowly tumble and become unreliable. Use turn coordinator + magnetic compass for attitude/heading. Timed turns: standard rate = 3°/sec.

Inadvertent IMC

Do not panic. Level the wings using turn coordinator. Maintain heading and altitude. Declare emergency on ATC frequency or 121.5. Request vectors. Trust your instruments, not your body.

178-second rule: average time from VFR into IMC to spatial disorientation for non-instrument-rated pilots.

Transponder Codes

7500 — Hijack. 7600 — Communication failure. 7700 — Emergency. Remember: 75 = taken alive, 76 = need a fix, 77 = going to heaven.
