What is the range of jet blast?

A large jet-engined aircraft can produce winds of up to 100 knots (190 km/h; 120 mph) as far away as 60 metres (200 ft) behind it at 40% maximum rated power. Jet blast can be a hazard to people or other unsecured objects behind the aircraft, and is capable of flattening buildings and destroying vehicles.

What is the danger area of a jet engine?

Jet Blast DataThis profile extends in line from the outboard wing-mounted engines to more than 200 feet behind some larger aircraft. Within this area, jet engines can generate hurricane-level exhaust forces approaching 100 knots.

How fast is a jet engine blast?

At full power, the exhaust wake speed can typically be 150 mi/h (130 kn or 240 km/h) at 200 ft (61 m) beyond the airplane and 50 to 100 mi/h (43 to 88 kn or 80 to 161 km/h) well beyond this point.

What happens if you stand next to a jet engine?

Yes. Human beings can get sucked into jet engines if they are close enough– this has happened multiple times in a number of aircraft ranging from A319 to A6E intruder. However, it happens only in rare cases- usually in case of miscommunication or a mistake, when safety procedures are not followed.

How fast is jet blast?

State-of-the-art in airliner engines means jet blast velocities exceeding 200 MPH out to a couple hundred feet at takeoff. Even idle thrust can produce velocities of up to 50 MPH out to 100 feet for some aircraft. Business jets pose a potential jet blast hazard as well.
