Flying displays by vintage jets will be "significantly restricted until further notice" following the Shoreham air disaster, the aviation regulator has said.
The Civil Aviation Authority (CAA) has placed new restrictions on air shows while the authorities conduct a thorough investigation.
Displays by vintage jets over land will limited to flypasts, which means high energy acrobatics are banned.
A statement by the regulator added: "The CAA will conduct additional risk assessments on all forthcoming civil air displays to establish if additional measures should be introduced."
Police have warned that the death toll from Saturday's crash in Shoreham could rise to 20 as teams begin recovering the plane's wreckage.
A crane has moved in to lift debris scattered when the 1950s Hawker Hunter jet plummeted on to the A27 after failing to pull out of a loop-the-loop stunt.
The CAA said it took steps on the day of the crash to ensure no further flights were made by Hawker Hunter aircraft and this restriction remains in place.
