KMYR has changed gate designations.  Starting and saving a new flight plan with correct new gate number does not stop Controller info from displaying the old gate number.  Where is this info stored so that I can make a correction?

In FSX it gets it from the flight plan as:

 

<?xml version="1.0" encoding="Windows-1252"?>

<SimBase.Document Type="AceXML" version="1,0">
    <Descr>AceXML Document</Descr>
    <FlightPlan.FlightPlan>
        <Title>KMIA to KJFK</Title>
        <FPType>IFR</FPType>
        <RouteType>HighAlt</RouteType>
        <CruisingAlt>35000</CruisingAlt>
        <DepartureID>KMIA</DepartureID>
        <DepartureLLA>N25° 47' 43.00" , W80° 17' 24.00",</DepartureLLA>
        <DestinationID>KJFK</DestinationID>
        <DestinationLLA>N40° 38' 23.00" , W73° 46' 44.00",</DestinationLLA>
        <Descr>KMIA, KJFK</Descr>
        <DeparturePosition>13L</DeparturePosition>
        <DepartureName>MIAMI_INTL</DepartureName>
        <DestinationName>JOHN_F.KENNEDY_INTL</DestinationName>
        <AppVersion>
            <AppVersionMajor>10</AppVersionMajor>
            <AppVersionBuild>60905</AppVersionBuild>
        </AppVersion>
 

RC has it on the controller page where you can change it if you wish.

 

In RC4 this has no function other than pronouncing it.
