What is the Standard Takeoff Minimums?

The standard takeoff minimums for Part 121 and Part 135 are regulations that limit the visibility value for pilots to takeoff. For takeoff, visibility is the controlling factor, we do not look at ceiling.
These are standard takeoff minimums, different companies may have exception CO78 or CO79 in their operation specification that allows a lower takeoff visibility minimum.

For Part 121, 125, 129, 135 (basically all operations that carry cargo or passengers) the minimums are:
- two engines or less—1 statute mile visibility
- more than two engines— 1⁄2 statute mile visibility
