Notes:Enroute from Avaré (SDRR) to the Helicidade (SIBH) heliport in Sao Paulo, on a routine repositioning flight. As a cold front approaches the area, a 35 knot nortwestern wind pushes us as we descend through 6500' over the aerodrome of Sorocaba (SDCO). A typical 55 minute leg was flown today in only 43 minutes!
