Flight Rules VFR IFR

Thu Oct 13, 2016 10:14 am

Novice question. In commercial aviation who decides on a flights use of VFR or IFR? I believe, and correct me if I'm wrong, once decided upon it can not be changed mid-flight regardless of weather conditions.

Airlines do NOT fly VFR only IFR. However for GA or Air Taxi aircraft that start off IFR can cancel and go VFR. Same in reverse a VFR aircraft can pick up and IFR clearance while airborne.

I meant a VFR aircraft can pick up AN IFR clearance while airborne.

Pretty much all scheduled commercial flights are done IFR. Only a select few flights on light aircraft are flown VFR (such as some sea-plane services and the likes), and even they probably often file an IFR flight plan.

The limitations of VFR flying would make it problematic to carry out scheduled flights.

Who makes the decision? That would depend on the company, route, aircraft, country/local regulations, season and weather. It could come down to the standard company procedures, or just the pilots/captains decision. In most decently sized airlines the flight plan is filed by an office, and the pilots just do whatever the route planners have told him to do. Some airports might not accept VFR traffic either.

You can change between IFR and VFR, it's a matter of notifying ATC what you want to do.

All Part 121 flights in the US (mostly airline flying) are conducted under IFR.

Although under very specific conditions airline OPSPECs allow a 121 flight take off under VFR, then within 50 miles of departure pick up the IFR clearance in the air. and vice versa, within 35 miles of the destination cancel the IFR clearance and proceed under VFR to the destination.

At my first airline, we routinely took off and landed under VFR, switching to IFR in the air when we got our clearance.

I kind of remember that at some point in the '90s, during yet another sudden ATC strike in France, a Wardair 747 captain decided to take-off from Paris (CDG, I believe) and fly VFR up to the English ATC zone. He decided there was not much risk, since nobody else was flying.

One thing to keep in mind is once you cross FL180, you need to be under IFR, so you wouldn't be able to go VFR even if you wanted to.

Would you please tell us more than one word? Why do you think it is incorrect? Single words are rarely informative.

It's correct if it's over the US.

Not Really, Class A Airspace ends at FL600 in the US, you can go VFR Over that. Also IFR only airspace starts in different places in different countries

Its also possible that a 121 flight can depart VFR from "non-radar" airports and pick up a clearance in the air.
