full operating capability nas level requirements
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
weather hazards caused by convection
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)

DRAFT

summary
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)
