The above wind factor table is for calculation of wind required to maintain present range capability at new
pressure altitude, i.e., break-even wind.
Method:
1. Read wind factors for present and new altitudes from table.
2. Determine difference (new altitude wind factor minus present altitude wind factor); This difference
may be negative or positive.
3. Break-even wind at new altitude is present altitude wind plus difference from step 2.
