Definition
A unit of fuel flow expressing the weight of fuel an engine consumes in one hour, measured in pounds. Used on performance charts and fuel flow indicators, particularly for turbine engines and many high-performance piston aircraft, because fuel weight (not volume) is what matters for range, endurance, and weight-and-balance calculations.
Plain English
How many pounds of fuel the engine burns in one hour.
Context Anchor
Seen in climb and cruise performance charts when fuel use is shown as a weight-based rate.
Why Pilots Care
Pilots use PPH values to calculate total fuel burn, endurance, and range before flight.
Intuition Check
Do not read PPH as gallons per hour. PPH measures fuel by weight, not by volume.
Example Sentence 1
At cruise power, the chart showed a fuel burn of 75 PPH.
Example Sentence 2
Multiplying the PPH rate by flight hours gives the total fuel needed for the leg.
