            Closed pattern flight profiles typically have a <termtext>pattern
            altitude</termtext>, which is the maximum altitude reached along
            the profile. Aircraft performing the closed pattern will typically
            ascend to the pattern altitude, fly level for some distance at
            that altitude, descend to just above a runway, perform a touch-and-go,
            and then repeat.

            It is not uncommon for the pattern altitude to be changed for
            one or more flight profiles. In this situation, you will need
            to keep your installation's BaseOps case up to date by changing the pattern
            altitude of those profiles. This lesson will teach you how to
            do this. It is presented as a list of step-by-step instructions.

            Go to the object type selector dropdown list in the upper-left
            corner of the BaseOps window, and select "Flight Profiles".

        <para>
            It may be useful to use BaseOps' filtering capability to display
            only those flight profiles of interest to you. Press the Filter
            button <img
            src='intres:BaseOps_FilterOptionsToolbarButtonBitmap'/>, located
            above the list on the left side of the BaseOps window, to
            display the "Filtering for Flight Profiles" dialog box.

        <para>
            Choose the radio button labeled "Display only those flight profiles
            that match the following conditions". Then, select the conditions
            that match the flight profiles of interest. For the purposes of
            this lesson, assume that we are interested in the
            profiles on flight track 5LC5.

                Once you have finished changing the pattern altitude, don't forget
                to go back and turn off filtering. Otherwise, you won't be able
                to see the other flight profiles in your BaseOps case.

            Type in the new pattern altitude, then press OK. The pattern altitude
            of the selected flight profiles will be updated.

            If desired, you can now run the BaseOps case and use NMPlot to
            see the effect of the pattern altitude change on your installation's noise
            contours. Other tutorials in this series cover how to run the
            case and view the noise contours.
