During what phases of flight can the spoilers be used?

Spoilers are used both in-flight and during takeoff and landing.

How many control modes are there on the elevators servo jacks?

three control modes
Each servojack has three control modes : . Active : The jack position is electrically-controlled. . Damping : The jack follows surface movement. . Centering : The jack is hydraulically retained in the neutral position.

What is ELAC in a320?

ELAC – Normally ELAC 1 commands the operation of the ailerons and ELAC 2 commands the operation of the elevators and horizontal stabilizer. ELAC 1 and 2 perform the following: Normal pitch and roll, normal LAF. Alternate pitch, alternate LAF.

What movement does the rudder control on an airplane?

yaw
The rudder controls movement of the aircraft about its vertical axis. This motion is called yaw. Like the other primary control surfaces, the rudder is a movable surface hinged to a fixed surface in this case, to the vertical stabilizer or fin.

What is power assisted control?

A system of flying controls in which the force needed to move the surface, although partly provided by the pilot’s effort, is supplemented by electrical, hydraulic, or pneumatic means. This was the system used in aircraft when power controls were introduced, and it is no longer in use. …

What is the purpose of primary stops?

Primary flight controls are required to safely control an aircraft during flight and consist of ailerons, elevators (or, in some installations, stabilator) and rudder.

What is FAC in aviation?

Forward air control is the provision of guidance to close air support (CAS) aircraft intended to ensure that their attack hits the intended target and does not injure friendly troops. This task is carried out by a forward air controller (FAC).

What is the landing speed of a A320?

Typical landing speed for an A320 is around 130kts to 140kts but again that depends on those following factors. As for landings in the mobile version, make sure your speed is consistent, check for weather conditions, check your altitude, and make sure you are at the right speed for each flap setting.

Can the A320 land itself?

Yes a plane can land by itself using a system that is often referred to as “autoland”. The pilots can program the auto-pilot to carry out the landing automatically whilst the pilots monitor the aircraft.

How are the ground spoilers compressed during an autoland?

One main landing gear strut is compressed. RETRACTION – The ground spoilers retract when the thrust levers are at idle and the speed brake lever is disarmed, or when at least one thrust lever is above idle. During an autoland, the ground spoilers extend at half speed 1 second after both main landing gear touch down.

What is a partial ground spoiler extension?

PARTIAL EXTENSION – Partial ground spoiler extension (10°) occurs when: Reverse thrust is selected on at least one engine with the other thrust lever at idle, and One main landing gear strut is compressed.

How do you extend the ground spoiler on a plane?

LANDING – Ground spoiler extension occurs automatically upon landing at touchdown of both main gear when: Both thrust levers are at forward idle if the ground spoilers are armed, or Reverse thrust is selected on at least one engine with the other thrust lever at idle if the ground spoilers are not armed

What are ground spoilers and how do they work?

Ground spoilers reduce the lift produced by the wings and hence transfer the weight of the aircraft to the landing gear, allowing a more effective wheel braking action. Their non or untimely extension has been a factor in the following types of A320 Family events:
