theres a question in the ATPL aerocourse book that I would sure like some opinions on .... it reads

Consider an airport with a Class C control zone . What would the status of the airport and its airspace classification when the tower is not operating ?

a. Controlled airport class E airspace
b.Controlled airport class D airspace
c. uncontrolled airport class E airspace
d. uncontrolled airport class D airspace

their answer is C

the problem I have with their answer is in RAC 2.8.3 ... it does say that the airspace does in fact become class E .... however RAC 2.8.5 does go on to say that E is controlled airspace but does not meet the requirements of ABCD

any input would be appreciated

Answer a - sorry - c.

Uncontrolled airport in class E controlled airspace.

Yes, their answer is correct. The Class C control zone (tower airspace) become Class E controlled airspace, although the airport itself is uncontrolled when the tower closes. Even though the airport itself is uncontrolled, you have to adhere to controlled airspace wx minima.

Thanks everyone for the feedback .... makes sense now ... had to read a little deeper into I guess
