Riding the Mountain Waves

Plane and Pilot

Often, turbulence is the harbinger of mountain waves, not the ideal ceiling—and visibility unlimited—day. FAA weather charts can help for higher altitudes but when just a few thousand feet agl, they may be less useful. We had been lifted above our assigned altitude.” We experienced moderate turbulence even at our gate.

How to Master Slow Flight (Step-By-Step)

Pilot Institute

Lift : The aerodynamic force generated due to airflow over the wings. The aircraft’s deceleration reduces the airflow over the wings, which reduces lift. When the lift force is less than the force of gravity, the aircraft descends. So, how do we increase lift to maintain altitude? Why does this happen?

Are Dry Microbursts Really An Invisible Trap? – Responding to Reactions

Chess In the Air

Most western pilots have patiently worked such lift for an hour or more while waiting for conditions to improve near their destination airport. Possible causes include: Rotor turbulence, e.g. on wave days. Dust devils and other extreme lifting motions can also cause havoc near the surface. This is another great point.

What Is a SPECI and When Is It Issued?

Pilot Institute

Expect poor visibility, increased turbulence, and slippery runway surfaces. You should monitor the temperature closely during winter or in colder regions since icing can impact both lift and control. OVC010CB : Overcast layer of cumulonimbus clouds at 1,000 feet AGL. And if you see “TSRA,” that’s a red flag.

What is a Stall? – When Wings Stop Working

Pilot Institute

Stalls Cause a Loss of Lift A stall is not related to engine failure. This misunderstanding can lead to confusion and, in some cases, accidents, as some pilots concentrate on engine performance instead of addressing the actual problem, a loss of lift. Now, the wings have to produce more lift to support this weight.

What Is an Outflow Boundary Shown on a Surface Analysis Chart? 

Flying Magazine

Some gust fronts can be completely harmless or may be a precursor for an encounter with severe turbulence and dangerous low-level convective wind shear. These gust fronts often contain severe or extreme turbulence, strong and gusty straight-line winds, and low-level convective wind shear.

Power-on Stall: How to Recover

Pilot Institute

This creates boundary layer separation, resulting in a loss of lift. The turbulent air hits the horizontal stabilizer, which causes a vibration that can be felt throughout the aircraft. Be careful because retracting the flaps causes the center of the lift to move forward. What Is a Power-on Stall? You’ve got this.
