Dangerous goods, aviation security and environmental rules
This domain tests dangerous goods carriage, aviation security screening and environmental/noise restrictions.
Dangerous goods
Part 92 implements dangerous goods rules, aligned with the ICAO Technical Instructions. Shippers and operators must classify, package, mark, label and document dangerous goods correctly, and staff need training. Some items are forbidden by air; passengers may carry only limited quantities. The PIC must know what is on board and act on undeclared or leaking dangerous goods.
Security
Aviation security screening is carried out by Avsec. Restricted articles include weapons, explosives and prohibited items; liquids are subject to screening limits. Operators must refuse carriage if screening requirements are not met.
Environment and noise
Aircraft noise certification and aerodrome noise abatement procedures apply. Operating restrictions may include curfews, preferred runways and noise abatement tracks. The PIC must comply with published noise procedures unless safety requires otherwise.
Worked example
A passenger wants to carry a camping stove with fuel in the cabin. Reasoning: fuel is dangerous goods; it may be forbidden in carry-on or limited to approved packaging. The operator checks Part 92/ICAO rules and refuses if not permitted. Security screening is not the only control - the operator also has a duty.
Traps
Assuming small quantities are always allowed; confusing security screening with dangerous goods rules; ignoring noise procedures after an ATC clearance.
