Definition
A Federal Aviation Regulation that prohibits a commercial operator conducting operations under 14 CFR Part 135 from beginning an IFR flight to a destination airport unless current weather reports — or a combination of reports and forecasts — indicate that conditions at the estimated time of arrival will be at or above the authorized IFR landing minimums for that airport.
Plain English
This rule says a Part 135 operator cannot launch an IFR flight if the weather at the destination, at the time the flight is expected to arrive, is forecast to be below the lowest weather conditions allowed for landing there.
Context Anchor
Seen in commercial IFR flight planning, especially when checking whether a Part 135 flight may legally depart for a destination and what alternate planning rules may apply.
Derivation
14 CFR means Title 14 of the Code of Federal Regulations, the section of U.S. federal law covering aviation. Part 135 is the chapter governing commuter and on-demand commercial operations. The § symbol means 'section.' So '§ 135.219' is section 219 within Part 135.
Why Pilots Care
It ensures commercial flights have safe options if the destination becomes unusable due to weather.
Grounding Statement
Before departure, compare the destination weather at the estimated arrival time with the required instrument landing minimums; if the weather is too low, this rule says the Part 135 flight cannot start.
Intuition Check
Do not read this as an approach chart or a weather report. It is the regulation that tells a Part 135 operator when destination weather is legally acceptable for starting the flight.
Example Sentence 1
Before releasing the flight, the dispatcher confirmed the destination forecast met § 135.219 by showing ceilings and visibility above landing minimums at the estimated time of arrival.
Example Sentence 2
The pilot reviewed 14 CFR Part 135 § 135.219 to determine if the forecast conditions at the alternate met the regulatory requirements.
