A passenger whose alleged bomb threats forced an international flight back to Sydney will remain behind bars after a court appearance was delayed because of mental health concerns.
Muhammad Arif, 45, was charged with one count each of making a false statement about a threat to damage an aircraft and failing to comply with cabin crew safety instructions.
The Canberra man was set to appear before Downing Centre Local Court on Tuesday morning, but he would not cooperate with officers.
"Apparently, he is refusing to come out of his cell and they’ll have to extract him if he is to come to court," magistrate Greg Grogin said.
"We won’t force him out of his cell."
The court proceedings were adjourned three times before Mr Grogin formally refused him bail.
Arif’s lawyer, Mostafa Daoudie, said his client had "serious mental health issues" and didn't seem to understand the situation he was in.
Mr Daoudie planned to make an application for Arif to be assessed before being brought to court, adding his client was "not in the right state of mind".
Arif's case will return to court on Wednesday, when his legal team is expected to make a bid for his release.
The mid-air drama unfolded after flight MH122 left Sydney Airport for the Malaysian capital of Kuala Lumpur on Monday afternoon.
The pilot turned the plane around while it was over northwest NSW after Arif allegedly began yelling, making references to Islam and gesturing at a backpack he was wearing on his chest.
The plane returned to Sydney about 3.45pm before a three-hour standoff on the tarmac ended with Arif's arrest.
Passenger Edo Kahn said the situation on board escalated after the plane took off and the man began praying "really loudly".
"People thought maybe he was just scared of flying initially, but then it just sort of got worse as things progressed and the whole situation with him not letting go of his bag," he said.
Velutha Parambath, who was travelling with his young family, said the passenger began saying "Allahu akbar" and pointing to a bag next to him as the plane started taking off.
Others on board the flight said the man yelled at flight attendants, made threats and knelt in the aisle of the aircraft.
The 194 passengers and five crew were evacuated from the A330 aircraft and taken to the terminal unharmed.
But some criticised the AFP for the time it took officers to board the plane and arrest the man after the flight returned to Sydney.
"They could have disembarked us, they could have done something," Mr Parambath said.
"We were just isolated at the end of the runway and that was the scariest of all.
"If the plane actually had a bomb, I don't think we would be here today."
The AFP said officers acted once it was safe to do so.
NSW Police Commissioner Karen Webb praised the work of the flight crew, adding the three-hour response time for officers to enter the plane and arrest the man was "pretty good".
"We can never presume anything and you don't know whether this person was acting alone or he actually had other support on the plane or outside the plane," she said.
"The protocol in Australia is to negotiate, we don't storm planes, this is not TV, it's not the movies - we want to protect the lives of all passengers."
