Air show

The biggest military airshow in the world is the Royal International Air Tattoo, at RAF Fairford in England.

[1] On the other hand, FIDAE in II Air Brigade of the FACH, next to the Arturo Merino Benítez International Airport in Santiago, Chile, is the largest aerospace fair in Latin America and the Southern Hemisphere.

[2] Some airshows are held as a business venture or as a trade event where aircraft, avionics and other services are promoted to potential customers.

Most aviation authorities now publish rules and guidance on minimum display heights and criteria for differing conditions.

Air shows often, but do not always, take place over airfields; some have been held over the grounds of stately homes or castles and over the sea at coastal resorts.

The first public international airshow, at which many types of aircraft were displayed and flown, was the Grande Semaine d'Aviation de la Champagne, held Aug. 22–29, 1909 in Reims.

Specialist aerobatic aircraft have powerful piston engines, light weight and big control surfaces, making them capable of very high roll rates and accelerations.

Because of these accidents, the various aviation authorities around the world have set rules and guidance for those running and participating in air displays.

For instance, slower, lighter aircraft are usually allowed closer and lower to the crowd than larger, faster types.

Also, a fighter jet flying straight and level will be able to do so closer to the crowd and lower than if it were performing a roll or a loop.

To gain such authorisations, the pilots will have to demonstrate to an examiner that they can perform to those limits without endangering themselves, ground crew or spectators.
