Jet blast

A large jet-engine aircraft can produce winds of up to 100 knots (190 km/h; 120 mph)[1] as far away as 60 metres (200 ft) behind it at 40% maximum rated power.

[2] Jet blast can be a hazard to people or other unsecured objects, and can reach wind speeds comparable to those of a Category 5 hurricane, causing roof failure or total collapse in buildings, and severely damaging or destroying things like mobile homes, utility buildings, and trees.

Pilots of light aircraft frequently stay off to the side of the runway, rather than follow in the centre, to negate the effect of the blast.

[3] Maho Beach in Sint Maarten is famous for its unique proximity to the runway of Princess Juliana International Airport, allowing people to experience jet blast, a practice that is discouraged by the local authorities.

[4] Skiathos Airport in Greece similarly allows people to experience jet blast, as its runway is located near a public road.

In 2003, aboard the USS Abraham Lincoln (CVN-72) , a jet blast deflector is raised hydraulically to protect one F/A-18 Hornet from the jet exhaust of another.
