So SVFR rules apply when transiting the Class C and Class D airspaces. After exiting the Class D, is the helo pilot required to adhere to normal cloud clearances? Operating in that area the Class E airspace begins 700' AGL correct? With an 1100 AGL Overcast it would be impossible to operate in the Class E adhering to VFR cloud clearances, as being 500 feet below the clouds would put you below the Class E, in which case you would be in Class G and need to remain clear of clouds with 1 mile vis, correct? Just making sure I understand the legal operation of this type of flight....I understand the SVFR rules are slightly different for helicopters as well...?
