Increasing V1 for a headwind
I've never heard this is an approved procedure, is it ever done?
Certainly take off distance is affected by headwind, however the few jets I've flown did not use a different v1 based on wind. My thoughts are that increasing V1, where a headwind exits, would provide a shorter balanced field length than a V1 not adjusted for headwind, and thus allow a higher take off weight for a balanced field situation
Does this make any sense?
