BobTait CPL Air Law Book, revision 1, Air Practice Exam 1 - Question 6 (page: 175).

Question reads: "Which of the following statemetns is applicable to the carriage of cargo near an emergency exit"
Page 181 says the answer is 6(a) being:
"cargo may obstuct an emergency exit provided that the emergency exit sign for that exit shall be covered"
(which I think is wrong or out of date .... could some please please help confirm/clarify?)

.... BECAUSE / BUT ...
MOS 91.600 Carriage of Cargo / Compilation No. 93 Compilation date: 02/12/2021 Registered: 13/12/2021
(www.legislation.gov.au/F1998B00220/latest/text/2)
....
(c) cargo (other than passenger service equipment or galley equipment in an aisle on a temporary basis while in use) must
not obstruct an aisle;
(d) either:
(i) cargo must not obstruct, or restrict access to, an emergency exit; or
[which would make " D - Delta " a much better answer being: "cargo shall not obsturct an emergency exit under any circumstances"

(and then again at Q32) ... Air Practice Exam 1 - Question 32 (page 180)
Question reads: "Which rule applies to the carraige of cargo in an aircraft"
Page 181 answer says its 32 (c) being:
"all cargo shall be properly restrained"
> WHY is this a better answer than "(A)-Cargo shall neve obstruct an emergency exit" ( in light of the 91.600 above ) ?

Because, 91.600 clearly states in d part ii that you MAY carry cargo in a manner which obstructs or restricts access to an emergency exit, provided that you have an approval from CASA.

As such, the statement "in any circumstances" in the question false, as, there exists circumstances where it IS legal to obstruct an emergency exit.

There is, however, no legal argument for not properly restraining cargo.
