Definition
In aviation risk management, the inability to know in advance exactly how a flight will unfold because conditions, equipment, people, and decisions can change between planning and completion. It is a built-in feature of flight that pilots must plan for, not a problem that can be eliminated.
Plain English
You can never know for sure what will happen on a flight. Weather shifts, plans change, things break, and people make mistakes. Good pilots accept this and build margin into their planning.
Context Anchor
Seen in risk management and decision-making discussions, especially before a flight or when conditions start changing in flight.
Derivation
Future comes from a Latin word meaning “going to be.” Uncertainty means “not settled” or “not known for sure.” Together, the phrase points to something important in flying: the result has not happened yet, so the pilot must deal with what is still unknown.
Why Pilots Care
Recognizing future uncertainty prompts pilots to plan for unknowns instead of assuming everything will go as expected.
Grounding Statement
If the weather is forecast to get worse later, the flight may be safe now but still contain future uncertainty.
Intuition Check
Future uncertainty does not mean simple nervousness about the future. In this context, it means a real unknown in the planned flight that could affect safety later.
Example Sentence 1
Because of future uncertainty, the pilot filed an alternate airport even though the forecast at the destination looked good.
Example Sentence 2
Good risk management means acknowledging future uncertainty rather than hoping conditions stay the same.
