Thanks to facebook friends I have found two new websites that will be helpful predicting wind flows for our flight across from Mozambique to Madagascar in July.
Windytv.com and earth.nullschool.net both offer a moving map which shows the wind and other weather indications at different altitudes. You can therefore check to see what would be the best altitude to fly at to minimise any headwinds and hopefully fly with the wind. We will be crossing the Mozambique Channel, flying east from Vilankulos in Mozambique to Toliara in a 4 1/2 hour flight (or more if there is a headwind.) The aircraft carries 6 1/2 hours fuel, and any headwind would seriously impact on the range we can fly.
