The future

  • Accurate and consistent forecasting
  • Investment into product development
slide-5

  • WMO commitment to the principle of free

and unrestricted exchange of meteorological and related data and products

TAF

  • Flight time range 30 mins VHHH-ZGGG

up to 16 hrs VHHH-KJFK

  • TAF issued every 6 hours for 24hr - 30hr
  • Short range forecast can benefit both

short haul and long haul flights

slide-10
SLIDE 10

With marginal weather

  • VHHH-ZGGG Flight time 30 mins
  • Remain on ground in VHHH or depart?
  • VHHH-KJFK Flight time 16 hours
  • Depart not knowing if aircraft can land

Wind and Temperature

  • Improve accuracy and updates
  • Longer flight, greater the effect flight

time and fuel

  • Temperature affects climb capability

resulting in increased fuel flow

Threats

  • HIWC (High Ice Water Content)
  • Convection
  • Volcanic Ash
  • Turbulence

Future

  • Many private companies offering data and

alerting systems, but operate independently.

  • For maximum benefit the industry

requires a global approach

slide-35
SLIDE 35

Summary

  • Consistent,accurate and frequent forecast/

updates to aid proactive decision making, including refined use of TEMPO/BECMG

  • Improved weather charts & digital solutions
  • Global solutions lead by observatories
