The inquest jury has heard that Jimmy Mubenga died after a struggle on board the plane.
Karon Monaghan QC, Assistant Deputy Coroner for Hammersmith and Fulham, said that three Detention Custody Officers - Terence Hughes, Stuart Tribelnig and Colin Kaler - restrained him after he went to the toilet.
She said: "A struggle ensued between Mr Mubenga and the three DCOs (Detention Custody Officers). Mr Mubenga was then restrained, handcuffed and placed in a seat."
She went on: "At some point it appears that he fell silent and unresponsive, and it became clear that something was wrong."
She said that Mr Mubenga was being deported back to Angola after serving a two-year prison sentence for assault occasioning actual bodily harm. The inquest at Isleworth Crown Court is expected to last eight weeks.
