John Downey, 61, was arrested at Gatwick Airport in May.
On Friday he spoke only to confirm his name at a preliminary hearing at the Old Bailey courthouse in London.
Downey is accused of being responsible for a car bomb left in South Carriage Drive which killed the soldiers as they rode through the park to the changing of the guard.
The explosion injured other members of the Royal Household Cavalry and killed seven horses as they travelled from their barracks to Buckingham Palace.
Downey is charged with murdering Roy Bright, Dennis Daly, Simon Tipper and Geoffrey Young, and with intending to cause an explosion likely to endanger life.
Judge Mr Justice Sweeney continued his conditional bail.
Downey, who wore a dark suit, white shirt and dark tie for the hearing, is due to stand trial at the central London court next January.
Following Downey's arrest in May, Sinn Féin MLA Gerry Kelly branded the move "vindictive, unnecessary and unhelpful".
He claimed the arrest breached a previous agreement from the British government on resolving the position of the on the runs.
"John Downey received a letter from the NIO in 2007 stating that he was not wanted by the PSNI or any British police force.
"Despite travelling to England on many occasions now six years on he finds himself before the courts on these historic charges," Mr Kelly told UTV at the time.
