Wasmer Consulting BaseOps User's Guide Editing Point Objects
Many of the objects in a BaseOps case represents point locations. These include:
Navigational Aids - Visual or electronic devices used to guide aircraft along their intended flight paths. Navigational aids serve as anchors for radials and DME arcs: see Editing Radials and DME Arcs. They are also displayed on maps to aid in the editing of flight tracks and flight profiles: see Editing Flight Tracks and Editing Flight Profiles.
Waypoints - Named geographic reference points used by aircraft in navigating their routes. Since flight paths are often specified with respect to waypoints, it can be useful to display waypoints on maps when editing flight tracks and flight profiles: see Editing Flight Tracks and Editing Flight Profiles.
Points of Interest - Locations of special interest where a detailed noise analysis will be performed. Typically, these are locations with a heightened sensitivity to noise, such as hospitals and schools. See Computations Performed.
VTOL Pads - Locations where vertical-takeoff-and-landing (VTOL) aircraft can takeoff and land. VTOL pads (also known as helipads) are often used as the anchors for flight tracks: see Editing Flight Tracks. VTOL pads are used by the AAM and RNM noise model.
Static Pads - Designated locations on an airfield where aircraft engines are run during maintenance and repair work. Static pads serve as the anchors for static profiles: see Editing Static Profiles. Static pads are used by the NMap and AAM noise models.
BaseOps can import waypoints, navigational aids, and VTOL pads from DAFIF. See Importing Information from DAFIF.
The different types of point objects are all edited in a similar manner. Therefore, only navigational aids will be discussed in detail. Keep in mind, however, that the following instructions (with the exception of the navaid type) also apply to other point objects.
To work with navigational aids, choose Navigational Aids from the object type selector dropdown list. Navigational aids can be added, duplicated, and deleted as described in Working with the List Pane. You can use the Add mouse tool to add new navigational aids by clicking on the map; see The Add Mouse Tool.
Navigational aids have the following properties.
Name - A short (10 characters maximum) name that uniquely and unambiguously identifies the navigational aid.
Long Name - A one-line (80 characters maximum) name for the navigational aid. The long name can be more descriptive than the short name. It is optional: if you do not supply a long name, the short name will be used in its place when necessary.
Notes - Miscellaneous information about the navigational aid. There is no restriction on the length of notes. Press the Enter key to insert additional lines.
Location - The location of the navigational aid. You can change the coordinate system used to specify locations: see Setting the Case Coordinate System.
Using the Select and Edit map tool, you can drag the navigational aid to another location on the map. See The Select and Edit Mouse Tool for more information.
NavAid Type - The type (VOR, TACAN, DME, etc.) of the navigational aid. Specifying the type is not strictly necessary. However, doing so is useful for documentation purposes, and future versions of BaseOps may allow you to display different types of navigational aids using different map symbols.
The navigational aid types are defined in the NavAid Type group: see Using Groups. If desired, you can add additional types.
Points of Interest have two additional properties: the noise level reductions when windows are open and closed. These properties are used when calculating the Probability of Awakening noise metric. Suggested default values are 15 dB for windows open and 25 dB for windows closed, which correspond to national averages for residential construction per FICAN 1992.
