Question: What Is P.I.O Aviation?

What causes Pio?

The majority of severe PIO events result from some deficiency in the design of the aircraft Flight Control Systems (FCS) that result in an adverse coupling of the pilot with the aircraft. Startle Effect can also result in a PIO.

What is pilot in the loop?

Pilot in-the-loop oscillation (PIO) or aircraft- pilot coupling (APC) is an interaction between a pilot and aircraft that causes sustained aircraft oscillations to occur over a range of amplitudes and frequencies.

What causes airplane to porpoise?

Porpoising can be caused by misjudging where the ground is, improper use of trim, forcing the aircraft onto the runway, or letting the nose drop prematurely. When this happens, the aircraft will float as you flare due to greater-than-normal lift. The worst thing you can do at this point is push the nose down.

Why does a plane bounce when landing?

There are two primary causes of bounced landings: landing hard, and landing too fast. Airspeed is another common cause of bounced landings. If you land with too much airspeed, and you force the aircraft down in a flat attitude, your airplane simply isn’t ready to stop flying.

How do you recover from a balloon landing?

In many cases, a slight balloon can be recovered by gently relaxing back pressure on the yoke/stick while still maintaining a nose-high pitch attitude, descending into a second flare, and touching down. You may have to use a slight amount of power to cushion the landing.

What’s more dangerous takeoff or landing?

Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. 49% of all fatal accidents happen during the final descent and landing phases of the average flight, while 14% of all fatal accidents happen during takeoff and initial climb.

How fast are planes going when landing?

Most commercial planes take off at roughly 160 to 180 MPH, while landings take place at approximately 150 to 165 MPH.

Why do planes land so hard?

Hard landings can be caused by weather conditions, mechanical problems, over-weight aircraft, pilot decision and/or pilot error. The term hard landing usually implies that the pilot still has total or partial control over the aircraft, as opposed to an uncontrolled descent into terrain (a crash).
