B) Is it legal to fly in the above conditions?


Depends on what airspace you need to be in. If your departure point is in uncontrolled airspace you would be able to fly as the minimums required is 1 sm visibility while remaining clear of cloud.

You would not be able to fly into controlled airpace as your minimums are 3 SM visibility, 1 sm horizontally and 500ft vertically from cloud.

That being aid it is possible to enter or leave a control zone by requesting special VFR.

For more on weather minimums see this TAKE FIVE from Transport Canada.


 

C) What are the weather minimums for SVFR?


You need one half statute mile of visibility and to remain clear of cloud. As the pilot you must request SVFR and if there are any IFR aircraft in or outbound you will not be given it.


D) What type of cloud is this?



This photo was taken last summer at a remote spray setup with Black Hawk Helicopters.


This is Mammatus clouds typically associated with cumulonimbus clouds. These bulges are formed by subsiding air within the cloud.
