Special VFR

[Jonathan]

Interesting. Are there other categories, aside from few, scattered, broken, and overcast?

1-2-3 = few
4-5 = sct
6-7-8-9 = bkn
10 = ovc

Metric system.

aviatrixfss, 400ft and 3SM are IFR conditions to me too for sure.

[poke-her player]

As far as I'm concerned, 400ft and 3sm IS IFR conditions!

you kids are so cute. I love this Idea..........VFR flying is cancelled for the spring and fall, I'm sure you won't affect any float operators.

[Bushav8er]

Intelligent reply 'poke-her player'. If you'd read the post you would have seen the the discussion is regarding 'controlled' airspace, in which case everyone is right - its NOT VFR. Unless you are flying floats through such an area -no worries, but if you are please review the regs.

I still think its crazy 3 miles in general can be considered VFR. I remember going up after completing my PPL on a day vis was about 3 miles around the airport, and maybe 5 further on. I of course took my limits into consideration and just wanted to do it to see what minimal VFR was actually like. I wonder how many accidents have been caused by pilots entering min-VFR and hitting ground (or another Aircraft flying in 3 miles) because they took off thinking they had their VFR minimas.

[poke-her player]

that's not min VFR, 300' and clear of cloud is min VFR. sometimes the Wx is to bad to go IFR but still good to go VFR. With the approach ban in effect and vis required at over a mile, it's legal and usually safe to request a special to get into an airport that would otherwise have an approach ban which means the operator now has a smaller fuel reserve which means the plane can legally carry more weight.

I love the CARs.

either way yes CFIT is an issue in aviation but 3 miles would not really be considered Min VFR

SVFR procedures now leaves the determination of whether the ceiling will affect flight within the zone in the pilot's hands. However, the rule requiring pilots to maintain 500 ft AGL and 500 ft clear of cloud did not change. The SVFR rule change was made to allow flight within the zone without having to request SVFR when the conditions allowed it. I'm seeing pilots using the rule change now to transit the zone when it's obvious the conditions are not appropriate.

I don't know what conditions you consider inappropriate but I would be quite interested to know what commercial flight experiance you have and where you gained that experiance?

I observe the same thing, but also with arrivals and departures. Many times ceiling was around 600ft and crew departed / arrived anyway without SVFR. How can this be possible?

[GilletteNorth]

Pilots do not issue the METAR. I'M the one doing the weather observing and reporting the conditions within my control zone. I'm not a commercial pilot. What I AM is a FSS with years of experience observing weather conditions. If you are a pilot, it's fairly obvious what conditions I'm referring to. I can easily see low clouds that are overcast and quite stable and uniform in their height above the ground. I have many methods of determining that cloud height quite accurately. I can also watch supposedly VFR aircraft transitting my zone within sight underneath those very same clouds. All it will take is one or two instances of an IFR aircraft doing the approach and popping out under the cloud deck coming too close to or even colliding with a low flying VFR aircraft transitting the zone without having requested SVFR when it should have, for the decision that changed the method of applying the SVFR rule to be reversed again.

I should mention that the rule concerning 500ft AGL and clear of cloud does not apply to departing/arriving aircraft. You may be less than 500 ft AGL but still have the requirement to remain clear of cloud during arrival/departure.

Here's an example of my concern. My control zone has a 5nm radius and has a water aerodrome 3 nm south of the main airport. That means during conditions of an overcast ceiling below 1000 ft, an aircraft coming in from the north to land at the waterbase must fly 8 nm under low cloud to get to the waterbase. There is higher and lower terrain in the vicinity. If there ever is a crash I wonder if Transport Canada will allow someone to argue that they needed to fly a low level 8 nm long final. They usually circle to line up into wind within the last 2 nm which is the actual landing phase. What comes before is called transitting.

Remedial training seems to be in order.

1) What airspace are you operating in? Towards? AIM 2.8
2) What are the VFR weather limits for those Classes of airspace? AIM 7.7.3
3) What is the minimum enroute altitude? AIM 5.5 Min Alt - VFR /AIM 5.6 Min Alt - Overflying Aerodrome

An airport with a dashed line around it is a 'control zone' and weather limits for such are 3 mi, 1m and 500' clear of cloud and 500' agl. You can not apply the 500' from cloud and no agl rule for class E as it is based at 2200' agl! The zone maybe class E but it IS A CONTROL ZONE! (AIM 7.7.3 Fig 2.7) Request the Special.
Additionally, if you are transiting a 'zone' you are deemed OVER an airport and that has to happen at 2000'. Please stay clear if you do not have to be there.

That's right but when they have departed, or before they start their "arrival phase", they must be 500ft AGL and 500ft from clouds. Therefore in order for a pilot to depart or arrive when ceiling is below 1000 ft, the ceiling MUST be higher outside the airport so when they are not in arrival or departure phase, ceiling is 1000ft or higher.

Actually the rule concerning 500ft AGL and clear of cloud does not apply because you are in a Class E Control Zone. They can be less than 500' BUT the ceiling still has to be 1000' (VFR) to allow the 500' cloud clearance, otherwise a Special to depart/arrive IS required. If the airspace they are entering on departure from the 'zone' is Class G and they intend to remain below 2200' agl, all they need is 'clear' of cloud (plus required vis). If they intend to climb above 2200' the ceiling would have to be 2700' to allow them to be the 500' clear (below) of cloud. Don't forget that a 'transition zone' may be around the airport basing the class E at 700' agl; class G below.

The only time clear of cloud applies is when the airspace & airport lay in class G which is topped at 2200' agl.

yep, and remember those Wx limits drop the second we leave the control zone so the only thing standing between a legal flgiht acomplished and a phone call from transport enforcment is people in your position.

so if I'm 100 miles north of Yellow knife at FL170 what class of airspace am I in?

[poke-her player]

Just for shits and giggles can some one tell me why there are distances from cloud at night?

[Bushav8er]

You have to ask? Class G and only because you (I assume) are nowhere near airways or airports which is what the Class E surrounds. Remember, again, we are talking about Special VFR and that means Control Zones.

Just for shits and giggles can some one tell me why there are distances from cloud at night?

Because if they didn't S P E L L* I T * O U T people like you would think that at night its okay to enter cloud just because you can't see them. Its TCs way of saying; day or night - same rules apply BUT you need more vis at night. I think too that TAFs, METARs and GFAs apply - you should have in idea where you'll find cloud - avoid it.

Now please stop trying to stir the sh*t and let those that don't get it, and want to learn, do so without dumb comments - thanks.

alright you busted me.......I know there's a pretty picture of Airspace and the different rules for vis anyone have a link to it?

Fair question - here's the link -

Bushav8er, I for one appreciate all the time you put in on this. Did it ever feel like beating a dead horse ? No need to reply.
