Study Notes
Mode C Transponder
- Mode C transponders are responsible for encoding aircraft altitude and position for air traffic control.
TAF and Visibility
- Terminal Aerodrome Forecast (TAF) indicates a minimum visibility of 1 statute mile, even if METAR reports 1.5 statute miles.
AIRMET Definition
- AIRMETs are alerts to modify the Graphical Flight Rules (GFA), providing critical weather information to pilots.
SIGMET Purpose
- SIGMETs (Significant Meteorological Information) are issued to notify pilots of hazardous weather conditions that may affect flight safety.
VOLMET Description
- VOLMET broadcasts report essential meteorological information including TAF, METAR, SIGMET, and high-frequency (HF) communication.
Mode S Transponder
- Mode S transponders support Traffic Collision Avoidance System (TCAS), enhancing situational awareness related to nearby aircraft.
Wind Direction from Low Pressure
- In a low-pressure system, wind typically comes from the northwest (NW).
Descend Rate and Temperature
- Colder temperatures result in a shallower descent rate due to denser air, influencing aircraft performance.
AutoPilot Principle
- Autopilot systems can adjust movement around the center of gravity (CG), allowing for stable flight path control.
Low Pressure System Identification
- A trough is identified as a characteristic of a low-pressure system, indicating areas of rising air and potential instability.
MALT and Positioning
- Minimum Altitude Layer Tracking (MALT) utilizes transponders to determine aircraft position and altitude.
ADS-B Characteristics
- Automatic Dependent Surveillance-Broadcast (ADS-B) does not provide collision advisory, a common misconception.
Cloud Base Height Calculation
- With a temperature of 18°C and a dew point of 12°C, the cloud base height is determined to be 2400 feet above ground level, utilizing the lapse rate of 2.5°C per 1000 feet.
Supercold Water Droplet Development
- The conditions for the development of large supercooled water droplets remain unspecified and are not clearly understood.
