I used to look at my master's face to see if it were sad or fierce; but I could not remember the time when it had been so uniformly clear of clouds or evil feelings.
In the case of VFR, aircraft reveal their locations by remaining clear of clouds so that other aircraft in their vicinity can spot them.
A variation on the visual approach--the contact approach--may be flown in lower-than-VFR conditions--you need only one-mile visibility and to remain clear of clouds. This truly is the IFR clearance equivalent of Special VFR.
The analysis provided enough detail to determine the planet's atmosphere is relatively clear of clouds and has a strong water signature -- also the best measurement of water to date on an exoplanet of this size.
Mike Hart's November 2017 article on flying in marginal VFR ("One Mile, Clear Of Clouds") was a good summary of the risks posed when flying in low visibilities and how to mitigate them.
The answer that surprises some is: clear of clouds. That's not to say some VFR target couldn't be hiding behind the puffball you decided to buzz, but 91.155 clearances don't apply.
One mile and clear of clouds is perfectly legal in certain airspace, but it can be absolutely insane if you are flying below the level of nearby terrain in narrow canyons where, on a good day, you get nervous doing a 180.
For those of you who've gotten a bit fuzzy on the VFR cloud-clearance rules, recall that a typical nontowered airport with instrument approach procedures has Class G from the surface to 700 feet AGL, which requires only a mile visibility and staying clear of clouds under visual flight rules.
Interestingly, no stations within a few miles either side of our route are reporting a ceiling, which means we might be clear of clouds (i.e., visible moisture) at altitude.
Class A None Class B 3 statute miles Class C 3 statute miles Class D 3 statute miles Class E less than 10,000 MSL Day 3 statute miles at or above 10,00 MSL Night 5 statute miles Class G more than 1,2000 AGL Day 1 statute mile less than 10,000 MSL Night 3 statute miles 1 statute mile more than 1,200 AGL 3 statute miles and at or 10,000 MSL 5 statute miles Class A None Class B clear of clouds Class C 500 feet belov Class D 1,000 feet above 2,000 feet horizontal Class E 1.000 real below.
That means that upon reaching a MAP with a following visual flight path, pilots may continue beyond the MAP without having the runway environment in sight as long as they have the required visibility, remain clear of clouds, and maintain visual contact with the ground.
If the reported ceiling at Dubuque was 900 feet AGL, you'd know from the elevations in the area that you'd be clear of clouds around 2000 feet MSL, surrounding obstacles and terrain notwithstanding.
