Definition
An FAA publication, issued as a section of the Terminal Procedures Publications, that lists nonstandard takeoff minimums and textual Obstacle Departure Procedures (ODPs) for instrument runways at airports where obstacles or other factors require them. Airports with nonstandard requirements are flagged on the corresponding instrument approach chart with a triangular symbol containing a 'T,' which directs the pilot to consult this publication for the applicable takeoff minimums and any textual ODP.
Plain English
It is the FAA booklet (and online document) that tells you, for a given airport, what weather minimums you need to legally take off on instruments and what specific path to fly after takeoff to stay clear of obstacles. If the approach chart shows a small black triangle with a 'T' inside it, you have to look in this publication before you depart.
Context Anchor
Seen in U.S. Terminal Procedures Publications and instrument departure planning, especially before an IFR takeoff from an airport with terrain, towers, or other obstacles near the departure path.
Why Pilots Care
They provide the only safe way to depart in marginal weather or near obstacles, directly preventing controlled flight into terrain during the most critical phase of flight.
Grounding Statement
Before an IFR takeoff, this information gives the minimum conditions and planned escape path needed to climb away from the runway safely.
Intuition Check
Do not read “minimums” as a general suggestion or comfort level. Here it means published conditions or actions that must be met or planned for before using that runway for an IFR departure.
Example Sentence 1
Before departing IFR from a small mountain airport, the pilot opened the Takeoff Minimums and Obstacle Departure Procedures publication and found a textual ODP requiring a climb to 6,000 feet on the runway heading before turning on course.
Example Sentence 2
After liftoff in low ceilings, the crew followed the published takeoff minimums and obstacle departure procedures to climb safely above the ridgeline west of the airport.
