How to Master Slow Flight & Fix Common Student Mistakes

Summary

In this video, Liz, the chief flight instructor at ThrustFlight, teaches the fundamentals of slow flight in a Cessna 172. She explains how to manage the aircraft’s speed, altitude, and power when flying at low speeds, particularly during takeoff and landing scenarios. The session covers key concepts like throttle control, flap settings, trim adjustments, and the effects of slow flight on control responsiveness. Liz also highlights common student mistakes and provides useful tips for maintaining coordination, including the importance of gradual flap retraction and applying the right rudder to avoid stalls.

Takeaways

• 😀 Power back to 1700 RPM and maintain level flight as airspeed decreases. Keep altitude steady as airspeed bleeds off.
• 😀 When airspeed drops below 110 knots, add the first notch of flaps (10 degrees). Continue adjusting as necessary to maintain altitude.
• 😀 Trim the aircraft to relieve control pressure after flap adjustments to maintain level flight and avoid altitude deviations.
• 😀 In slow flight, avoid stalling by maintaining an airspeed just above the stall warning (around 45-50 knots in the Cessna 172).
• 😀 Use back pressure on the yoke to maintain altitude when reducing power in slow flight. This prevents the aircraft from pitching down.
• 😀 When turning during slow flight, anticipate a drop in altitude due to loss of vertical lift. Compensate by adjusting power or pitch.
• 😀 Always perform flap changes gradually (one notch at a time) to avoid large pitch changes that could destabilize altitude.
• 😀 During recovery from slow flight, apply full power, allow the nose to drop, and then gradually reduce flaps to maintain control and avoid climb.
• 😀 Slow flight can feel ‘mushy’ with larger control movements required for small direction changes. Practice will build proficiency in managing control sensitivity.
• 😀 Rudder coordination becomes crucial in slow flight, especially with increasing left-turning tendencies. Apply right rudder as speed decreases and the angle of attack increases.
• 😀 Common student errors include failing to trim the aircraft properly after flap changes, and not managing control inputs to maintain altitude during recovery.

Q & A

What is the main focus of the slow flight maneuver explained in the video?

The main focus of the slow flight maneuver is to demonstrate how the aircraft behaves at low speeds, particularly in terms of control response, altitude maintenance, and handling near stall conditions.

Why is it important to practice slow flight as a student pilot?

Slow flight is crucial for understanding aircraft control near stall conditions, especially during takeoffs, landings, and maneuvers in the traffic pattern. It builds proficiency in managing airspeed, altitude, and aircraft configuration.

What happens to the aircraft’s control pressure when performing slow flight?

In slow flight, the aircraft's controls feel 'mushy' or less responsive. Larger inputs are required to make minimal changes in direction, especially at low speeds with full flaps.

What is the recommended airspeed for slow flight in a Cessna 172?

The recommended airspeed for slow flight in a Cessna 172 is around 45-50 knots, which is just above the stall speed.

How does the aircraft’s altitude change as it enters slow flight?

As the aircraft enters slow flight, the altitude may begin to decrease slightly due to the high drag and low power available at low speeds. Power adjustments are required to maintain altitude.

Why is trim so important during slow flight maneuvers?

Trim is important during slow flight because it helps relieve the control pressure required to maintain altitude. As flaps are deployed or airspeed decreases, the aircraft's pitch and handling characteristics change, requiring frequent trim adjustments.

What is a common error made by students during slow flight with respect to trim?

A common error is failing to adjust the trim after deploying flaps, which can cause the pilot to struggle with holding altitude and maintaining control, especially when transitioning to slow flight.

How does the application of power and pitch affect slow flight?

In slow flight, pitch is used to control airspeed, and power is used to maintain altitude. Reducing power leads to a decrease in airspeed, requiring back pressure on the yoke to maintain altitude, while more power is needed to compensate for high drag.

What does the instructor mean by 'mushy controls' during slow flight?

'Mushy controls' refers to the reduced responsiveness of the aircraft’s controls at low speeds, where large yoke inputs are needed to make even small changes in the aircraft's flight path.

What is the correct procedure for recovering from slow flight in the video?

To recover from slow flight, the procedure is to apply full power, push the nose down slightly to avoid climbing, gradually retract flaps in increments, and use trim to maintain altitude while allowing airspeed to build up.
