Study Notes
Wind and Weather Phenomena
- Surface wind decreases and backs at night due to friction and cooling effects.
- Weather radar can detect multiple phenomena including hail, snow, and volcanic ash; specifically, options A, B, and D are correct for detection capabilities.
Aviation Meteorology Terms
- METAR CCA indicates a Correct report in aviation weather.
- Prognostic charts forecast weather for a specific future time.
Flight Dynamics and Conditions
- Icing is most severe on an airfoil when conditions involve a thin wing and a speed of 250 knots.
- Warm air over a cold surface leads to smooth flight conditions at low altitudes.
Navigation and IFR Guidelines
- Each preferred IFR route typically starts or ends with navigation aids for accurate guidance.
- Inertial Navigation System (INS) determines aircraft position based on acceleration and time measurements.
Clearance and Reporting
- Oceanic clearance requires the longest route to be evaluated, along with any subsequent clearance needed.
- Pilot Reports (PIREPs) are essential for providing information about atmospheric conditions; options C, E, and G are relevant.
Visibility and Weather Conditions
- IFR outlook affected by ceiling and visibility typically arises from conditions like rain and mist.
- Isotach spacing for 30 knots within 90 nautical miles indicates potential for significant weather variability.
