What if your destination is a field "in" class E airspace. Does an IMC let you fly in the clouds until (say) 300ft above the
field. You then break out and land visually. Is that legal?
No, because in order to fly in IMC you'll need to flying IFR, one of the IFRs is the minimum height rule which states that you must be at least 1000ft above any obstacle within 10nm (?) of your track. Unless of course you are performing a published instrument approach procedure - see earlier discussion - where the minimum will be a function of the procedure and the rating (which will always be >300ft for the IMC rating).
