Aviation at the leading edge of science

Air Facts

The brothers believed that their lift was coming from smoke, which they could clearly see rising in the air. In letters to an English scientist, Sir Joseph Banks, dated December 1, 1783 and January 16, 1784, he described the balloon, and attributed the lift to “air rarified by heat”. The leading edge of science can be dangerous.

What Is Ground Effect?

Pilot Institute

Your wings don’t create as much drag as they would at higher altitudes, which gives you extra lift. Key Takeaways Ground effect increases an aircraft’s lift and decreases drag. Lift increases due to the high-pressure area created by the compressed air beneath the wings.

warm air being lifted rapidly aloft in the vicinity of mountainous terrain. 3,823 feet MSL the surface 700 feet AGL Correct! The most frequent type of ground or surface-based temperature inversion is that which is produced by: the movement of colder air under warm air, or the movement of warm air over cold air.

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?

How to Make Perfect Steep Turns (Step-By-Step)

Pilot Institute

A smaller bank angle will result in more lift, while an increased bank angle will reduce the lift. As an aircraft banks, lift is divided into horizontal and vertical components. The horizontal component of lift causes the aircraft to turn. Combining both components of lift, the total lift required increases.

How to Fly Perfect Lazy Eights

Pilot Institute

The higher speed creates extra lift, causing the airplane to bank further into the turn. The aileron on the right wing deflects down, increasing the camber and creating more lift. The left wing’s aileron deflects up, decreasing lift. The lift imbalance causes the roll. Perform the maneuver no lower than 1,500ft AGL.

Power-off Stall: Recovery Steps Made Easy

Pilot Institute

This can cause you to lose lift. Remember Bernoulli’s Theorem and how lift is created. The loss of lift causes the aircraft to stall and lose altitude. The ACS states that recovery should be completed no lower than 1,500 ft AGL for single-engine aircraft and 3,000 ft AGL for multi-engine aircraft.
