Eager passengers who stand up inside the cabin of a plane before it has reached its parking spot in Turkey will now face a fine.

The Turkish Civil Aviation Authority has brought in fines of €62, or about $A108, cracking down on those passengers who refuse to comply with the seatbelt rule.

Under the rule, passengers must remain seated with their seatbelts fastened until the plane has finished its taxi to it parking spot and the seatbelt sign has been switched off.

The rule is intended to stop overhead luggage from possibly injuring other passengers. It also stops the need for staff to repeatedly issue safety instructions.

Turkish Airlines, the country’s national carrier, has already updated its landing announcement.

It states: “Passengers who do not comply with the rules will be reported to the Directorate General of Civil Aviation through a Disruptive Passenger Report, and an administrative fine will be imposed in accordance with the applicable legal regulations.”

Turkish Airlines flies to 130 countries. Passengers will be subject to the rule on landing in Turkey. Other international airlines are yet to confirm if they will enforce the fine when landing in Turkey.

Earlier this week, Qantas promised to step up its own safety procedures following a shock turbulence event that injured three cabin crew in May last year. The incident happened during a descent into Brisbane Airport on a flight from Sydney.

Two crew members received minor injuries and a third had a fractured ankle, according to an ATSB report.

Qantas said it was planning on overhauling its medical assessments processes.

“Following an internal investigation, we promptly expanded our Group-wide medical escalation and post-incident medical assessment processes, ensuring all crew on-board a flight are assessed following an incident, regardless of visible impact,” Qantas said.
