Definition
A federally designated regional transportation planning body responsible for coordinating long-range transportation planning — including airport access, surface transportation, and related infrastructure — within an urbanized area of 50,000 or more people. MPOs are required by federal law for any such area to receive federal transportation funding, and they coordinate with state, local, and federal agencies, including the FAA, on projects that affect airports and aviation access.
Plain English
A regional planning group that decides how transportation money gets spent in and around a major city, including the roads, transit, and airport access that connect to local airports.
Context Anchor
A pilot may see MPO in airport planning, community development, or FAA-related documents rather than in normal cockpit operations.
Derivation
Metropolitan comes from the Greek metropolis, meaning 'mother city' — the main city of a region. Planning Organization is plain English: a body that plans. Together it names a group that plans for the region surrounding a major city.
Why Pilots Care
Pilots usually do not use MPO information in flight, but it can matter when an airport is being expanded, improved, relocated, or connected to local roads and public transportation.
Intuition Check
Do not read MPO as an aircraft part, cockpit procedure, or weather term. In this context, it means a regional transportation planning organization.
Example Sentence 1
The airport sponsor coordinated with the local MPO to ensure the new terminal access road was included in the regional transportation plan.
Example Sentence 2
Airport expansion plans must align with the MPO's long-range transportation strategy.
