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.
