What is the purpose of the elevators on the tail of the plane?

The elevator is the small moving section at the rear of the stabilizer that is attached to the fixed sections by hinges. Because the elevator moves, it varies the amount of force generated by the tail surface and is used to generate and control the pitching motion of the aircraft.

What is elevator trim stall?

Elevator trim stalls are most likely to happen in these scenarios: During a go-around procedure from a normal landing approach or a simulated, forced-landing approach. The trim is set for a normal landing, and when you add power for a go-around, your aircraft’s nose pitches up.

Why does a pilot trim an aircraft?

The purpose of trimming is to free the pilot from having to exert a constant pressure on the controls. This is often used to maintain straight and level flight, however trimming can also be used at any phase of flight – for example to maintain a constant rate of climb or descent.

How does the elevator work?

Elevators work via a pulley-esque system whereby a metal rope connects to the top of the elevator car that travels through a “sheave” in the engine room, according to Discovery. Thus, the sheave acts as a pulley wheel featuring grooves to hold onto the metal rope (also known as a cable) securely.

Where is the elevator trim control located on an airplane?

In most of the light aircraft , you will only find an elevator trim control in the cockpit. Rudder and Aileron trim controls are usually found on larger aircraft and only exist as a permanently deflected surface that needs to be altered by hand during the outside check of an airplane.

How to trim an elevator properly?

The proper technique for trimming the elevator is to first establish the desired pitch attitude with elevator control and then adjust the elevator trim to relieve the control pressure. It is particularly important to have the elevator trimmed properly for the correct speed on final approach.

What is the purpose of keeping the aircraft in trim?

Keeping the aircraft in trim relieves the pilot of the need to constantly hold elevator pressure one way or the other to maintain aircraft attitude. This helps reduce fatigue and prevents unplanned excursions from the desired attitude if the pilot gets distracted.

What is trimtrimming on a Cessna 172?

Trimming is done by small surfaces usually connected to the trailing edge of the ailerons, rudder and elevator called Trim Tabs. In a Cessna 172, the elevator trim is adjusted by a wheel which is located in the pedestal area. The wheel has a marking which clearly indicates the point where the elevator trim will be in neutral or take-off position.
