Good evening all,

Just completed a practice CLWA exam and I’m a bit confused on one question relating to an ADIZ.

“Any flight within an ADIZ will always be exempt from the “general requirements” for such operations if -
a) the flight does not proceed more than 5 nm of the point of departure
b) the flight originates from an aerodrome within the ADIZ
c) the true air speed is below 120 kt
d) the flight is conducted in CTA

I picked b) because it was more correct than a) when I read the bit in AIP

According to AIP ENR 1.12 paragraph 1.1.4 flights that are exempt from compliance with requirements in para 1.13 are
-a flight originating within an ADIZ which maintains a steady outbound track;
-a flight which remains within 10NM of the point of departure;
-aircraft performing published approach, holding or recovery procedures; and
-a flight conducted in accordance with special procedures arranged with the Area Air Defence Commander.

Just wondering if this is a typo or if I’m missing something here.

Cheers,
Mike

P.S Out of curiosity, I’ve never seen an ADIZ or even heard of them existing. Where are they?
