Convection and NAS-level NextGen Requirements at Full Operating Capability (FOC) DRAFT
Full Operating Capability NAS-Level Requirements • Core Team: Lead by Cheryl Souders. Bob Showalter, Lorraine Leonard, Steve Abelman, Cecilia Miner, Frances Bayne, James Tauss, Ernie Dash, Chnur Johnston, Jack May • Assumes NextGen Concepts of Operations & Weather ConOps • NAS-Level requirements. Not allocated to particular solutions • Single Authoritative Source (SAS) Weather Requirements • Primitive-Level • “Constructions”, if needed by user, are created outside the SAS using SAS information (freezing level, cloud layer, gust front, VIL) • Acknowledged some not achievable by FOC • Convection is a cause of aviation weather hazards. Convection itself, is not the hazard
What differences can you identify between this convection…..
Thunderstorm dangers can be far from heavy precipitation and lightning
Weather Hazards caused by Convection • Turbulence • Lightning • In-flight icing • Gusty surface wind speed and direction • Low-level wind shear • Hail • Tornado • Mesocyclone • Low ceiling and visibility • Heavy precipitation • Microburst (downdraft)
2025 FOC NAS-LevelSpatial Resolution Requirements for Weather Hazard caused by Convection DRAFT
Summary • FOC draft requirements are NAS-Level, not solution • Out for review by January 2011 • Assumes convection is a cause, not an explicit hazard • FOC “convective” requirements identify specific hazards • A “construction” which combines weather hazards caused by convection has been labeled the Convective Hazard Volume (CHV)
