What is region of reverse command in aviation?
Flight in the region of reversed command means flight in which a higher airspeed requires a lower power setting and a lower airspeed requires a higher power setting to hold altitude. It does not imply that a decrease in power produces lower airspeed.
What is the region of reversed command when will you experience it and how do you you maintain control of the airplane?
Flying at this speed means that you are on the back side of the power curve, also known as the “region of reversed command.” In normal cruise flight, you pitch the aircraft to maintain altitude, and power the aircraft to maintain airspeed.
Which can result when operating in the region of reverse command?
If allowed to slow several knots, the airplane could enter the region of reversed command. At this point, the airplane could develop an unsafe sink rate and continue to lose speed unless the pilot takes a prompt corrective action.
What does backside of the power curve mean?
Every airplane has a power curve. And every power curve has a backside. It’s an area of the performance envelope in which induced drag rises dramatically, necessitating considerably more power to maintain a given airspeed and altitude.
Where is the region of reverse command?
To the left of the best endurance speed is the region of reversed command, also referred to as the back-side of the power curve.
Why do we pitch for speed?
Most instructors (including us) have taught that when you’re on a glideslope, you pitch for airspeed and power for altitude. It makes sense. If you trim your aircraft for a specific speed, you can hold that speed at any power setting without touching the flight controls, because trim holds airspeed.
What happens when flying at the back side of the power curve?
It is important to note that when flying on the backside of the power curve, as the AOA increases toward the critical AOA and the airplane’s speed continues to decrease, small changes in the pitch control result in disproportionally large changes in induced drag and therefore changes in airspeed.
Why should an airplane be headed into the wind for the Pretakeoff check?
Why should an airplane be headed into the wind for the pretakeoff check? To obtain more accurate operating indications and to minimize engine overheating during run-up. Select the four flight fundamentals involved in maneuvering an aircraft. Straight-and-level flight, turns, climbs, and descents.
Why is it important for a pilot to understand fundamental aerodynamics?
As much as it seems sometimes that airplanes fly by magic, it’s important for every pilot to understand at least the basic fundamentals of aerodynamics. These principles dictate not only how the aircraft stays aloft, but what makes it either stable or unstable. Straight-and-level flight, turns, climbs, and descents.
Why do pilots practice slow flight?
The objective of maneuvering in slow flight is to understand the flight characteristics and how the airplane’s flight controls feel near its aerodynamic buffet or stall-warning. It also helps to develop the pilot’s recognition of how the airplane feels, sounds, and looks when a stall is impending.
What is the region of reverse command?
The region of reverse command is the region where the pitch power relationship becomes reversed. In normal flight (outside of the white arc) we use the pitch of the aircraft for altitude control, and the power for speed.
What is the use of pitch and power in reverse command?
In normal flight (outside of the white arc) we use the pitch of the aircraft for altitude control, and the power for speed. In the region of reverse command, it becomes reversed (obviously). The PITCH is now used for AIRSPEED control, and the POWER is used for ALTITUDE control.
Why is the reverse command maneuver so important?
It’s a foundational maneuver, and the region of reverse command is found not only in slow flight, but also approaches, and short field landings. It is essential for a safe and stabilized approach, which leads to safe, stabilized landings, which leads to feeling good about yourself, and happy insurance underwriters.
