Convection and NAS-level NextGen Requirements at Full Operating Capability (FOC)

DRAFT


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


What differences can you identify between this convection

A gust front is a convective hazard

A Gust Front is a Convective Hazard


Thunderstorm dangers can be far from heavy precipitation and lightning

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)

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)
