The incident took place on Regent Street in London on December 9 last year during a protest about student fees.
The NME reports Charlie Gilmour appeared at Westminster Magistrates' Court on Friday, in connection to an incident that saw him allegedly sit on the bonnet of a car carrying royal protection officers.
Gilmour is also alleged to have thrown a rubbish bin at the convoy, hitting a car, but not the one containing Prince Charles and Camilla, reports Sky News.
Accused of violent disorder, Gilmour did not enter a plea and the case was adjourned until March 25.
Last month, Gilmour was charged with violent disorder and "theft of a mannequin leg"; the theft charge has since been withdrawn.
Gilmour, 21, shocked many in Britain when he was photographed swinging from the Union Jack attached to the Cenotaph, Britain's most important war memorial, during the December demonstration; has has apologized for what he called a "terrible insult" to Britain's war dead.
