Start Stand Setup

When the Stand command is first launched, the Stand Setup tab is in the Start Stand Setup mode. When in this mode, parameters can be defined for commencing stand design.

Terrain

The top row in the Start Stand Setup tab controls the drawing X,Y plane or terrain on which the Stand session is to be placed.

• Unless a terrain object(s) has been added in Drawing Manager ->Terrains, the terrain list will be disabled, while the elevation (Z) cell will be active. This allows you to specify a drawing X,Y plane elevation for the session. See Start Stand Setup tab (Drawing X,Y plane) above. 
• If a terrain object(s) has been added in Drawing Manager -> Terrains, the terrain list will be enabled, and this terrain object(s) will be available for selection in addition to Drawing X,Y plane. See Start Stand Setup tab (Terrain) above.

Stand reference system

The second section in the Start Stand Setup tab controls the Stand reference system - a local X,Y coordinate system within which the positions and distances at the gate can be measured.

If the session has been placed on the drawing X,Y plane (i.e. a terrain object is not in use), the stand reference system also contains an arrow to specify the apron slope direction. It is critical that the stand reference system is placed at a position from which there is one uniform slope to the pavement area where airplanes are parked.

• X,Y: Refers to the origin position of the Stand reference system in drawing coordinates. 
• Elevation (Z): Refers to the elevation of the Stand reference system. The elevation is taken from the drawing X,Y plane or terrain at the origin X,Y point.
• Orientation: Refers to the orientation of the X-axis of the coordinate system in the drawing angle system.

Stand Setup

After inserting the stand reference system in the drawing, Start Stand Setup becomes the Stand Setup tab. The Stand Reference is a local x-y coordinate system in which the positions and distances at the gate will be measured and it also contains an arrow that is used to specify the Apron slope direction and grade. It is therefore important to place this Stand Reference at a position from which there is one uniform slope to the pavement area where airplanes are being parked.

Stand type

When Contact stand (with bridge) is selected, the Bridge tab is active. For non-contact (remote) stands, this box should be cleared.

Stand design coordinates

• Local stand coordinates: Displays the position of elements such as bridge rotunda(s), lead-in line(s) and apron service pit(s) in the drawing reference system (see More) (i.e., in relation to the local stand reference system origin).
  Note: The origin position of the Stand reference system is always shown in drawing coordinates.
• Drawing coordinates: Displays the position of elements such as bridge rotunda(s), lead-in line(s) and apron service pit(s) in the drawing coordinate system (see More) (i.e., in relation to the drawing origin).

Apron slope

Note: This is only applicable if a terrain model is not in use.

Grade

Set the percentage for the upward or downward apron slope of the apron by typing the value in the assigned field. Example: Type D0.5 and a downward slope of 0.5% is set. Move the cursor out of the field to continue.

Note: The  icon highlights the fact that this is a critical parameter which should be reviewed.

Direction

First set first the apron slope direction, measured from the reference location. Click the Drag button to define the direction (angle) of the slope in the drawing or type the value in the assigned field (A).

Note:

• L and R in front of the value represent left and right angle measured from the X-axis (left is towards the Y-axis and positive).
• The  icon highlights the fact that this is a critical parameter which should be reviewed.

More

Press the More button to access parameters that are likely to be edited relatively infrequently.

Stand reference system

• X,Y: Refers to the origin position of the Stand reference system in drawing coordinates.
• Elevation (Z): Refers to the elevation of the Stand reference system. The elevation is taken from the drawing X,Y plane or terrain at the origin X,Y point.
• Orientation: Refers to the orientation of the X-axis of the coordinate system in the drawing angle system. Click Rotate to set a new angle for the reference system.
