Study Notes
Turbulence and Weather Phenomena
- Areas of turbulence associated with mountains occur in and below rotor clouds.
- Hook-shaped radar patterns on weather radar indicate the presence of tornadoes.
WAAS (Wide Area Augmentation System) Considerations
- If LPV (Localizer Performance with Vertical Guidance) is unusable, flying is still permissible with BARO (barometric) and VNAV (Vertical Navigation) capabilities.
- WAAS/GPS challenges highlight LPV as the correct option, easily identifiable in available choices.
Meteorological Processes
- The process of water vapor transitioning directly to ice crystals is known as deposition.
Aircraft Surveillance Systems
- Multilateration (MLAT) relies on transponder signals for accurate positioning.
Altimeter Settings
- When pressure readings exceed 31.00 inHg, the altimeter setting adjusts by 0.1 inches, translating to a height change of 100 feet and visibility reduction of 1/4 statute mile.
Radar Wave Frequencies
- LF (Low Frequency), MF (Medium Frequency), and HF (High Frequency) radar waves exhibit varying frequencies, increasing during the day and decreasing at night.
