  2. Airfield traffic pattern - Wikipedia

    en.wikipedia.org/wiki/Airfield_traffic_pattern

    Traffic patterns can be defined as left-hand or right-hand according to which way the turns in the pattern are performed. They are usually left-hand turns because most small airplanes are piloted from the left seat (or the senior pilot or pilot-in-command sits in the left seat), and so the pilot has better visibility out the left window.

  3. Passing loop - Wikipedia

    en.wikipedia.org/wiki/Passing_loop

    In the example layout shown, trains take the left-hand track in their direction of running. Low-speed turnouts restrict the speed in one direction. Two platform faces are needed, and they can be provided either at a single island platform or two side platforms (as shown). Overtaking is not normally possible at this kind of up-and-down loop as ...

  4. Facing and trailing - Wikipedia

    en.wikipedia.org/wiki/Facing_and_trailing

    Turnouts facing and trailing. Note that this diagram is for left-hand traffic; for right-hand traffic, "F" and "T" would be swapped. Facing or trailing are railway turnouts (or 'points' in the UK) in respect to whether they are divergent or convergent. When a train traverses a turnout in a facing direction, it may diverge onto either of the two ...

  5. Drill commands - Wikipedia

    en.wikipedia.org/wiki/Drill_commands

    Left flank march or left turn, it is still the same even on the march for some countries: All members marching 90° turn to the left, done by rotation on the right ball and the left heel. Right incline (U.S.: Column half-right, march ), is a half turn to the right, usually used when a flight, squad, platoon, etc. is not in its proper alignment.

  6. Catch points - Wikipedia

    en.wikipedia.org/wiki/Catch_points

    A facing turnout is used to prevent any unauthorised movement that may otherwise obstruct the main line. [1] The trap points also prevent any damage that may be done by a vehicle passing over points not set for traffic joining the main line. [2] In the United Kingdom, the use of trap points at siding exits is required by government legislation. [2]

  7. Continuous-flow intersection - Wikipedia

    en.wikipedia.org/wiki/Continuous-flow_intersection

    A continuous flow intersection (CFI), also called a crossover displaced left-turn (XDL or DLT), is an alternative design for an at-grade road junction. Vehicles attempting to turn across the opposing direction of traffic (left in right-hand drive jurisdictions; right in left-hand drive jurisdictions) cross before they enter the intersection.

  8. Quadrant roadway intersection - Wikipedia

    en.wikipedia.org/wiki/Quadrant_roadway_intersection

    This roadway adds two three-way intersections in addition to the original four-way intersection, moving all left turns (in right-hand traffic countries) or right turns (in left-hand traffic countries) from the main intersection. The design is intended to improve traffic flow by reducing signal timing phases from four to two in the main ...

  9. Excavator controls - Wikipedia

    en.wikipedia.org/wiki/Excavator_controls

    Additionally there is a switch on the right hand joystick to operate attached tools. The most commonly used control pattern throughout the world is the ISO controls. In the ISO control pattern, the left hand joystick controls Swing (left & right) and the Stick Boom (away & close) , and the right hand joystick controls the Main Boom (up & down ...
