Definition
A section of Title 14 of the Code of Federal Regulations, Part 135, that prohibits a pilot from beginning an IFR flight to a destination airport under Part 135 operations unless the latest weather reports or forecasts (or any combination of them) indicate that weather conditions at the estimated time of arrival will be at or above authorized IFR landing minimums for that airport.
Plain English
This rule says a Part 135 pilot cannot start an instrument flight to an airport unless the forecast shows the weather at arrival time will be good enough to legally land there.
Context Anchor
Seen in discussions of weather planning for Part 135 operators, especially before launching an instrument flight.
Derivation
The symbol “§” means “section.” In aviation regulations, “§ 135.219” means section 135.219 of the federal aviation rules, not a weather value or procedure name.
Why Pilots Care
It defines the legal weather floor that commercial operators must meet to keep IFR flights safe and compliant.
Intuition Check
Do not read § 135.219 as a weather minimum by itself. It is a legal citation that points to the rule requiring the destination weather to meet the applicable landing minimums.
Example Sentence 1
Before releasing the charter flight, the dispatcher confirmed § 135.219 was satisfied because the destination forecast showed ceilings and visibility above ILS minimums at the ETA.
Example Sentence 2
During the approach briefing the captain confirmed the current visibility and ceiling satisfied § 135.219 minimums.
