Please remember that weather forecasts can be just plain wrong at times. As the weather deteriorates what do you do? I cannot tell you what you can or cannot do, but I am sticking to “Personal Minimums”.
These include any pressures involving the flight.
What if I want to raise my minimums? I can use training with an instructor to set higher personal minimums. This way I know where I draw the line and what I am up against.
How fast can 7 miles visibility deteriorate? Here is my example flight at KFCM (Yes, this was planned and with a very capable Instrument rated instructor) in a Cessna 172. And now I can honestly say I would never want to try this without more training.
