Este es un blog para aquellas personas que me han preguntado como configurar el simulador de vuelo de Google Earth para usarlo como simulador de manejo.
Advertencia: Al configurar el simulador para usarlo de esta forma, quedara inactivo el Avion F16, para volver a recuperar la configuracion original se deberá reinstalar Google Earth.
PASO 1
Tres Archivos de configuracion de Google Earth deberan ser modificados, los archivos se modifican manualmente, esto cambiara todos los parametros de aerodinamica, velocidad, elevación, etc del F 16 y se comportara como un vehiculo terrestre:

Al abrir borraremos todo el contenido, y lo reemplazamos por el que abajo se indica en letras rojas:

% Keyboard controls for typical PC keyboard with numeric keypad. Controls
% for a single-engine aircraft with two main wheel brakes DB_0 (left) and DB_1
% (right). Attention: Key names are uppercase only!
%
% Key names are as defined in Qt, but without the Key_ prefix. See
% http://doc.trolltech.com/3.3/qt.html#Key-enum
%
% Keys can be defined with modifiers: Shift, Control, Alt, Meta.
%
% Variable names are:
% DF, DG: Flaps, gear (0 = retracted, 1 = extended)
% DA, DE, DR: Aileron, elevator, rudder (-1..1).
% DE_T: Elevator trim (-1..1).
% DP_i: i-th power lever (counting from 0; (0..1)).
% DB_i: i-th wheel brake (counting from 0 (left brake); (0..1))
%
% Manipulators are:
% set(var, value): Set var to value.
% add(var, delta [, min, max]): Add delta to var, keep it between min
% and max if given.
% toggle(var): Set var to 0 if it's 1 or to 1 otherwise.
% toggle(var, min, max, step) Change var between min and max adding step.
%
%
% This keymapping works well on standard US keyboards with NumLock switched off
% and on reduced keyboards without the numeric keypad by providing some
% alternate mappings. Also works with most European type keyboards, as the
% only punctuation characters used are the period and comma (for brakes).
%
% The key_press list defines actions to be executed on key presses with
% an optional modifier key. For set() statements with nonzero value, the
% corresponding variable is set to zero when the key is released.

Listo, ahora nuestro F16 funcionará como todo un autobus o tractocamion, pero para aumentar el realismo, utilizaremos una superposicion de imagen que simule una cabina, para ello sigamos el paso 2
PASO 2
Descargaremos el siguiente programa:
http://freegeographytools.com/upfiles/ScreenOverlayMaker.zip
Descargaremos alguna de las siguientes imagenes, para la cabina a elegir:
IRIZAR PB
AUTOBUS SCANIA
VOLVO TRUCK
KENWORTH T 2000
Ejecutamos el programa Screen Overlay Maker:
1.-SELECT OVERLAY GRAPHIC FILE: Seleccionamos el archivo .png de la cabina que hayamos descargado.
2.-PRESET POSITION: Center
3.-SAVE AS: Seleccionamos un nombre para el archivo kml el cual abriremos desde Google Earth
PASO 3
Abriremos google earth, e iremos a la posicion desde la cual queremos iniciar.
Antes de iniciar el vuelo, abriremos el archivo kml de nuestra cabina: Archivo/Abrir/cabina.kml
El archivo se guardara en Lugares Temporales, para evitar abrir el archivo cada que iniciemos google earth lo arrastraremos a Mis Lugares
Se debe iniciar el simulador seleccionando Herramientas/Entrar al simulador de vuelo o Ctrl+Alt+A y seleccionamos F 16 y Vista Actual, iniciemos solo cuando ya tenemos nuestra posicion a una altura cercana al suelo, de lo contrario empezariamos el viaje en el aire con una configuracion terrestre, lo cual nos estrellaría casi de inmediato.
Al iniciar el Simulador, seleccionamos Ver/Barra Lateral, ya que las imagenes de las cabinas estan configuradas para trabajar con la barra lateral, esto nos beneficia al tener una imagen menos distorcionada de los caminos y por supuesto una velocidad mayor de descarga de imagenes.
Ahora si, dispongamonos a iniciar nuestro recorrido.

RECOMENDACIONES
Algunos lugares de EUA por ejemplo tienen muy definido el relieve del terreno, por lo que se dificulta la navegacion pues el terreno esta muy accidentado, para ello, dependiendo de la region que escojamos para viajar, en el menu Herramientas/Opciones/Vista 3D/Exagerar Elevacion y ahi escogemos de 0.3 a 0.5, por ejemplo en una zona montañosa es mas facil navegar en 0.3 para que sea mas realista el paisaje y no tan inclinado el camino.
Podemos seleccionar entre otras cosas viajar de dia o de noche con el menu Ver/Atmosfera, o bien en la Capa Tiempo seleccionamos Nubes y veremos en el horizonte la nubosidad en tiempo real.
Al iniciar el simulador, con Alt+Flecha abajo, inclinamos la vista a nuestro gusto para que la imagen de la cabina no nos impida ver parte del camino.
Es posible voltearse al tomar una curva a una velocidad inadecuada, esto lo hace mas realista, en caso de que te suceda, te saldra un mensaje "Tu avion se ha estrellado" debes salir del simulador de vuelo pues si seleccionas Reanudar vuelo iniciaras desde el aire.
Con "H" borramos el HUD el cual esta configurado para solo mostrarnos la Velocidad, la escala de aceleracion, así como la posición central.
La velocidad esta indicada en Millas Nauticas, para conocer la velocidad en Km/h multiplicamos las millas nauticas por 1.85, por ejemplo 54 millas equivalen a 100 km/h, la velocidad maxima es de 130 km/h pero esta varía dependiendo de la altitud, pues a nivel del mar se puede alcanzar un poco mas de velocidad.
