Study Notes
Weather and Flight Operations
- GFA indicates lowest low-pressure location at 1800Z, positioned east of CYDB.
- METAR reveals cloud coverage: few clouds at 170, broken at 190, overcast at 250; indicates 5/8 to 8/8 of the ground concealed by clouds for an aircraft flying at FL220.
- Strong winds at an airport in a deep valley attributed to the funnel effect.
- If LNAV/VNAV is unusable according to WAAS NOTAM, approach is still feasible with LNAV and barometer onboard.
Aircraft Safety and Procedures
- Radar altitude is associated with Ground Proximity Warning System (GPWS).
- Hydroplaning risk on runway with standing water equivalent to CRF 10.3.
- Encountering thunderstorms (TS) requires maintaining altitude and power without attempting a turn back.
Aviation Terms and Acronyms
- NC in SIGMET stands for "no change."
- PIREP indicates strong tailwind during descent for a specific airport.
- Keywords related to WAAS include LPV (Localizer Performance with Vertical guidance).
Aircraft Systems
- Aircraft lightning detection systems can identify various conditions, including static charge behind mountains; be cautious about selecting misleading options in assessments.
