Landing Roll (ICAO Definition)
Landing Roll- After touchdown until aircraft exits the landing runway or comes to a stop, whichever occurs first. Landing roll is a sub phase of the landing phase of flight.
roll - A rotational motion in which the aircraft turns around its longitudinal axis. Pushing the control stick to the left will raise the aileron on the left wing and lower the aileron on the right wing.
Roll (bank) - in which one wing of the airplane moves up while the other moves down in the aircraft's frame of reference. This is typically controlled by ailerons on the wings of the airplane.
Roll
A rotation of an aircraft around the longitudinal axis. This effect is produced by the ailerons.

Roll A maneuver in which an aircraft rotates about its longitudinal axis.
Roll (maneuver) The airplane keeps the nose pointed in one direction while it rolls over on its back and then upright again.
ROLL - Of the three axes in flight, this specifies the action around a central point. Compare PITCH and YAW.

You use rudder rather than brakes to control rolling heading. If you can set a localizer frequency the CDI has a one dot range of 70 feet to each side. Keep the CDI centred.
Dutch Roll or Lateral - Directional Oscillation
This motion exists in any airplane for which the ratio of static directional stability and dihedral effect lies between the limiting conditions for spiral divergences and directional divergence.
landing roll - the distance an aircraft travels on the ground after touchdown to the point it can be stopped or exits to the taxiway.
Roll response is faster than you might imagine. I tried a max stick deflection exercise from 60 degrees left to 60 degrees right, and the airplane responded far more quickly than a Skyhawk or Skylane.

Service Ceiling: Altitude at which cabin crews can serve drinks.

ROLL One of three axes in flight, specifying the action around a central point.
roll - A basic aircraft maneuver, used to rotate or turn the aircraft to one side along its longitudinal axis, created by an up or down motion of the wings.
h. A "Roll-out" on final approach not less than 1/4 mile from the landing threshold and not less than 300 feet above the ground.
OVERLYING CENTER- The ARTCC facility that is responsible for arrival/departure operations at a specific terminal.
Barrel Roll - Unloading the beer for a hangar party.
Caged Gyro - Not much more docile than a wild gyro.

Carburetor Icing - A phenomenon happening to Aero club pilots at exactly the same time they run out of gas.
Cyclic, Roll Axis
This part of the exercise is similar to what we just discussed in the pitch axis, however you need to use even more caution. If you allow the helicopter to skid laterally, you risk dynamic rollover.
During take-off roll the pilot can be under the impression that the aircraft is ready to fly. Again caused by ground effect which reduces induced drag.

- an instrument in an airplane which displays the relative bearing to an NDB (see below) -- it essentially "points at the NDB" AI Attitude Indicator (also known as AH - Artificial Horizon) - an instrument which provides the pilot with pitch and roll ...
aileron - A small hinged portion of an airplane's wing, used to make an airplane roll, or turn around its long axis.
Roll rate is enhanced by servo tabs on the ailerons which deflect opposite to the ailerons and make the control force much lighter. The disadvantage is that they reduce the maximum roll effect at full travel.
Enhanced artificial horizon with pitch and roll information. It is part of a flight director system.
ADT: Approved Departure Time
AFB: Air Force Base
AFCS: Automatic Flight Control System. It is an advanced autopilot.
The air-traffic control system also plays a huge roll in the National Airspace System.
Aircraft Roll Motion A roll motion is caused by deflecting the ailerons which causes the wings tips to move up and down.
V:Port is one of Virgin Atlantic’s flight entertainment systems - currently offered on B747-400s and A340-600s, although the aim is to roll it out across all aircraft in the future.
After the torque effect, the other main problem was the tendency of the helicopter to roll laterally in the direction of the retreating rotor blades as the advancing blades pass through denser air and generated greater lift than the retreating ...
This marked the first (and, thankfully, only) instance of an Argosy being involved in an automobile/aircraft incident, with a car driven by Miss Betty Kaufman having just entered the overpass while the Argosy was on it s landing roll.
Wing dihedral contributes to good roll stability, and the stabilator can be trimmed for hands-off level flight, even in turns. Deploying the flaps causes a mild pitch change that is easily trimmed away.
View from right side, fast transition, distance 150 feet, altitude 0 feet, preference Roll.
The full span provides maximum high lift (flaps) for the entire wing and roll controllability (ailerons) at a minimal weight since both functions are shared by the same control surface (flaperon), with a simple mechanical ‘mixer' controller.
The movement is roll. Lowering the aileron on one wing raises the aileron on the other. The wing with the lowered aileron goes up because of its increased lift, and the wing with the raised aileron goes down because of its decreased lift.

Peel a small section of metallic tape that measures no more than a half-centimeter by half-centimeter. The smaller the section, the more precise your adjustments will be.
It detects movement in the roll, pitch, and yaw axes that pilots know so well.

The problem that Juan encountered was that as his gyroplane would start to fly, it would invariable roll to the left and crash. Models he built using lightweight rotors did not experience this.
An aircraft's stability is expressed in relation to each axis:
lateral stability (stability in roll), directional stability (stability in yaw)
and longitudinal stability (stability in pitch).
Aileron: A control surface on fixed-wing aircraft, usually mounted on the aft edge of wings, which controls roll, and is controlled by the wheel.

The cylindrical bombs developed by Barnes had to be dropped from 60 feet to skip into the dam face and roll down it to explode at a depth that triggered a pressure fuse.

He demonstrated the use of inclined, rigid wings to provide lift and roll stability, and the use of a rudder steering control. He even came to realize that an area of low pressure is formed above the wing.
