Wind & Temp Interpolation

Enter wind and temperature at two pressure altitudes — the tool interpolates both for your target altitude.

Lower Level

Target Altitude (ft)

Must be between the two levels

Wind and temperature will be interpolated for this altitude.

ℹ️ Wind interpolation decomposes each wind into U (west–east) and V (south–north) components, linearly interpolates each, then recombines. Temperature is linearly interpolated between the two levels.

About This Calculator

📋 Data is sourced from the PA-28-161 Warrior III POH, Section 5 (Figure 5-23a)
⚙️ Calculated for 65% power, Best Economy Mixture at 9.2 GPH
📐 Values between table altitudes and temperatures are linearly interpolated
🌡️ The ISA standard temperature lapse rate is 2°C per 1,000 ft below 36,090 ft
