What is the purpose of the FA (Area Forecast) in dispatch planning?
Answer: To describe general weather conditions over a large geographic area for enroute planning
The Area Forecast describes general weather conditions over broad geographic areas and is used by dispatchers for enroute weather planning.
What minimum visibility is required for an alternate airport to be listed under 14 CFR Part 121 alternate minimums?
Answer: At least 1-2-3: ceiling 1,000 feet and visibility 3 miles for precision, 2,000 and 3 for non-precision
Under Part 121 alternate requirements, precision approach alternates require 600-2 and non-precision require 800-2, though the simplified 1-2-3 rule is used for filing alternates.
What does a freezing level at 5,000 feet MSL mean for dispatch of an aircraft without de-icing equipment?
Answer: Potential structural icing risk exists below 5,000 feet in visible moisture
With a freezing level at 5,000 feet, any flight through visible moisture below that altitude risks structural icing on an aircraft without de-icing equipment.
Which weather product provides the best information for planning routes around convective activity?
Answer: Convective SIGMETs and WSR-88D radar data
Convective SIGMETs combined with current radar data provide the best real-time picture of thunderstorm location, intensity, and movement for route planning.
What is the primary hazard associated with mountain wave turbulence during dispatch planning?
Answer: Extreme turbulence and rapid altitude changes that can exceed aircraft structural limits
Mountain wave turbulence can produce extreme vertical air movement that may exceed aircraft structural limits and cause sudden loss of altitude.
How does temperature inversion affect low-level turbulence and visibility for dispatch?
Answer: Inversions trap pollutants and moisture below, reducing visibility, while the top of the inversion can produce wind shear turbulence
Temperature inversions trap pollutants and moisture, reducing surface visibility, and the shear zone at the inversion top can produce significant turbulence.
