A NPPL is not permitted to fly in IMC & cannot add an IMC rating to the licence, therefore to comply with VMC would involve remaining in VMC & not entering IMC.
Complying with VFR would involve not flying under IFR.
Seems clear enough to me
----------------------------------------------
"How, exactly, does one "comply" with VMC? And how does that differ from complying with VFR?"
Simples. VMC minima change according to level, qualification, airspace, and aircraft type. To be VFR you must comply with these minima.
Please don't tell me you are unaware of the minima YOU require, as per ANO?
Both wrong.
IMC = "Instrument Meteorological Conditions"
VMC = "Visual Meteorological Conditions"
IFR = "Instrument Flight Rules"
VFR = "Visual Flight Rules"
VMC are those conditions under which flight by VFR is permitted.
There is a difference. It's a differnce it is important to understand, and it's clear from the answers above that at least two people here don't.
As rata2e says, these minima change depending on various factors. Those factors, however, don't change the definition of VMC.
If you fly in less than the conditions required by the rules, you aren't failing to comply with VMC. You are failing to comply with VFR.
If you are flying along quite happily above 3,000', 9999 vis, and flying VFR, and everything in the garden is rosy, but then the cloud begins to descend and you can no longer maintain the distance from cloud required, you don't bust VMC. You bust VFR.
It's the
Rule that you break. You don't break the
Weather Conditions.
