Piper PA-22 Tri-Pacer CO₂ emissions per flight hour

A year of flying in a Piper PA-22 Tri-Pacer

Costs are for the yearly plan, from $0.035 per kg with lower rates as the amount grows. The monthly plan is $0.036 per kg, and one tonne once is $40.

On the monthly plan, offsetting an hour in a Piper PA-22 Tri-Pacer costs about $2.38. See plans

How we calculate this

Burning one US gallon of avgas releases about 8.31 kg of CO₂, so CO₂ per hour is fuel flow multiplied by 8.31. The figure covers combustion only, not producing or transporting the fuel.

Your real fuel flow depends on power setting, mixture, altitude and how much of the hour you spend climbing. If your logs give you an average burn, multiply it by 8.31 for a closer number.

CO₂ per 100 nautical miles is CO₂ per hour divided by the cruise speed of 113 knots, times 100. It describes cruise: a climb burns more fuel for each mile.
