In aviation, the term "slipstream" refers to the flow of air pushed backward by an aircraft's propeller or jet engine. When it comes to aerodromes (airports), this slipstream becomes a significant factor during ground operations.
Slipstream is generated by aircraft engines — either jet exhaust or propeller wash. When a plane powers up, the airflow behind it becomes turbulent and strong. Depending on the aircraft type, engine power, and positioning, the slipstream can cover a large area.
Managing slipstream is critical for safety. Jet blast and prop wash can create forces strong enough to flip lightweight objects or cause serious injury. Engineers address this by using:
While both involve air movement, slipstream happens on the ground due to engine thrust, while wake turbulence occurs in the air due to lift and wingtip vortices. Understanding both is crucial for airfield operations.
It’s the high-speed airflow from aircraft engines on the ground during taxiing or takeoff preparation.
Yes, it can be hazardous to people, vehicles, and nearby aircraft if unmanaged.
By using blast fences, operational restrictions, and well-marked taxi zones.
Jet blast comes from jet engines; prop wash is from propeller aircraft. Both contribute to slipstream but differ in power.
It can affect nearby aircraft on the ground and contribute to scheduling and spacing considerations.
No. Larger jets generate stronger slipstreams, and smaller aircraft are more vulnerable to being affected.
