Wingtip Vortices and Wake Turbulence

Pilot Institute

By far the strongest component of wake turbulence is the swirling air generated at the tips of the aircrafts wings. Key Takeaways Wingtip vortices, not engine exhaust, create the strongest wake turbulence. Wake turbulence can cause severe roll and structural damage to smaller aircraft. How Are Wingtip Vortices Formed?

Quick Crosswind Calculation for Pilots

Pilot Institute

Quick estimates improve decision-making Helps with landing technique, wake turbulence, and IFR corrections. Crosswind is referenced in terms of knots, a fancy aviation term for nautical miles per hour . Example 1 Aircraft heading: 070 Wind Direction:160 Wind Strength: 25 knots This example is super easy. knots 20 0.34

How to Read a Windsock

Pilot Institute

Standard FAA aviation windsocks are calibrated to fully extend at a wind speed of 15 knots. How To Read a Windsock Hanging limp : Winds are under 3 knots. Extended halfway: Winds are around 7-8 knots. Fully Extended : Winds are strong, likely 15 knots or higher. Moving erratically : Conditions are gusty or turbulent.

Turbulence

Air Facts

Turbulence Air Facts Journal Space is infinite in its complexity. And tampering our mental reserves with turbulent mischief. Turbulence is unpredictable. All three axis of an aircraft are subject to the vagaries of turbulence. Space is also infinite in its potential. And there in lurks the adventure.

Managing the wind

Air Facts

Though wind is reported using such simple numbers like 270@15G20, I’ve come to believe that 20 knots here is not always the same as 20 knots there. Subjective factors such as terrain, turbulence, and gust direction are as important as the numbers. Then came the landing in 20 knots in the Hill Country of Texas, west of Austin.

Hail Damage Rattles A320 Passengers

AV Web

“I think we were about 20 minutes from landing when we got into a cloud of hail and thunderstorm, and the turbulence started,” Emmeley Oakley, a passenger on the flight, told ABC News. The radome is a relatively thin fiberglass structure that is no match for hailstones at 200 knots.

Flight Review: Van’s RV-12 LSA—Singular Success

Plane and Pilot

In order to be flown by a sport pilot, the resulting airplane must still meet the current regulations—1,320 pounds maximum gross weight, 120 knots max cruise speed, for example—but how it gets there is up to the builder. Airplanes in the LSA category have some performance limitations, so the RV-12 gets right to the 120-knot max cruise figure.
