Definition
Software tools — typically computer-based or tablet-based applications — that allow a pilot to plan a flight from start to finish, including route selection, weather review, fuel calculations, weight and balance, performance data, navigation log creation, and filing of flight plans. These systems consolidate multiple preflight tasks into a single integrated workflow.
Plain English
Apps or programs that help a pilot plan a flight, doing the math, weather check, route, and paperwork in one place instead of using lots of separate tools.
Context Anchor
Used during preflight planning, especially when checking the route, fuel needed, weather, and expected aircraft performance before a flight away from the local area.
Derivation
Mission comes from a Latin word meaning “to send.” In aviation, a mission is the flight you intend to carry out, not necessarily a military task. A system is a set of parts working together, so a mission planning system brings many planning details together for one flight.
Why Pilots Care
They reduce risk by identifying problems early and support safer, more efficient flights that comply with regulations.
Intuition Check
Do not read “mission” as meaning only a military mission. Here it means the planned flight and what that flight needs to accomplish.
Example Sentence 1
Before departure, the pilot used a mission planning system on her tablet to build the route, check weather, and calculate fuel for the cross-country.
Example Sentence 2
Before departure the student used a mission planning system to check weather along the planned route and select a suitable alternate airport.
