Headwinds
Hi all first post here im student pilot,i have a question for any current CPL/ATPL pilots,
On a flight from Tokyo nrt to hkg crusing @ fl370 (A330-300 )with a headwind of 181kt / gs 308 /@ m0,74 and a fuel burn of 3460ph
would it be better to decend to
fl 240 with a headwind component of 73kt /gs 371/@ m0,74 and a 3824ph fuelburn presuming atc cleared.
Would the increase in groundspeed justify the increased fuelburn, and also would company SOP/ICAO allow this.
any help would be great.
thanks
