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 gauges to plan endurance, range, and fuel reserves.
Plain English
How many pounds of fuel the engine burns in one hour. If the gauge reads 80 PPH, the engine is burning 80 pounds of fuel each hour at that setting.
Context Anchor
Seen in performance charts, especially when fuel use is listed by weight instead of gallons.
Why Pilots Care
Allows pilots to calculate fuel endurance and range directly from chart values during flight planning.
Intuition Check
Do not read PPH as the total fuel on board. It is a rate: pounds of fuel used each hour.
Example Sentence 1
At cruise power, the chart showed a fuel flow of 95 PPH, giving us about four hours of endurance with reserves.
Example Sentence 2
The pilot used the PPH figure to confirm the aircraft could reach the destination with adequate reserves.
