VOR TRAINER

Use your device in landscape orientation. In portrait, the app will ask you to rotate the device; if your system does not rotate the screen automatically, rotate it manually.

The Main View, used for navigation, occupies most of the screen. The side panel groups the OBS (Omni Bearing Selector) and PROA (heading)/airspeed indicator instruments, the controls that display the radial lines, and other items. This guide follows the same reading orientation: landscape, scrolling up and down as needed.

With no saved Preferences, the mobile version starts with the PROA instrument shown in the panel and OBS 1 selected. The 2D view opens maximized, with the small picture-in-picture (PiP) window displayed. Magnetic variation (declination) is set to −24°, and the aircraft is drawn with its classic outline. The red and blue lines are on in both 2D and 3D; the white line is on in 3D and off in 2D.

With PROA displayed, tap the left half of the dial to decrease the heading by 1°, or the right half to increase it by 1°. Keep your finger pressed and, after a brief delay, the heading continues to turn.

The ◀ left and right ▶ tap areas also operate the OBS: each tap changes the value by 1° to the left or right. These tap areas do not use the press-and-hold repeat of the PROA dial.

If the instrument is currently showing the airspeed indicator, first use the small round toggle button to bring up PROA. Speed is set by dragging the airspeed indicator needle anywhere between 60 and 120 knots (KIAS).

The OBS dial lets you select the course for the active VOR station.
Tap the left half to decrease CURSO by 1° and the right half to increase it by 1°. Keep your finger down to continue adjusting. On the course instrument shown over the 3D Main View, the repeat also starts after a brief delay.

The active VOR is the station currently used by the OBS instrument and by the Radial Window. The number shown on the OBS instrument indicates the current selection.

Tap the round button next to the OBS instrument in the panel to switch between the two stations. When the Radial Window is open, its VOR 1 and VOR 2 tabs also select the station.

When switching VORs, wait for processing to finish before starting another action.

The small control next to the instrument switches between PROA and the airspeed indicator.

On the airspeed indicator, press anywhere on the scale between 60 and 120 knots and drag to set the cruise speed. When you release, the value is rounded. The center of the dial is not an adjustment area.

Speed cannot be edited during BOOST or while radials are being selected in the Radial Window. This instrument's display mode and the cruise speed are Preferences saved between sessions.

If you prefer, reduce the cruise speed instead of increasing the distance between stations.

NAV (Autopilot): turns automatic tracking of the selected course on or off. Once you have chosen a course, bring the aircraft close to the corresponding radial before engaging. NAV is accepted only when capture conditions allow; check the indications on the panel and the audio cues (which may not work on your mobile device) to confirm that NAV has actually engaged.

With NAV engaged, automatic tracking flies the aircraft and blocks manual turns. Note: changing the course disengages NAV.

BOOST: triggers a temporary acceleration, then returns to the cruise speed currently set. While the cycle is running, pressing it again does not start a new one. Boost is not a permanent speed setting.

While radials are being edited (a blocking operation), flight controls are suspended. Finish or close the editing window before maneuvering again.

In this mobile version, tap the NAV and BOOST buttons on the panel. The button color shows which function is active, as does a pink outline around the aircraft.

The larger view is the Main View. The smaller view is the PiP (Picture-in-Picture). One can be 2D while the other is 3D.

The swap control next to the views selects which one occupies the main area. The PiP control shows or hides the smaller view; this is not the same as swapping the Main View.

When available, the button with the four-corners icon switches the app to full-screen mode.

If your browser does not support 3D, the app indicates that it is unavailable. There is no need to open a different version of the simulator.

Tap the swap-views icon, or double-tap an empty area of the larger view, to switch the Main View. The 2D/3D button on the panel turns the smaller view on or off.

When the radial value editing window is not open, pinch to zoom the 2D map in or out (PiP or Main View). Zooming in follows the aircraft; pinching back in returns to the original zoom level.

• Red: shows/hides the selected course.
  
• Blue: shows/hides the line dividing the TO and FROM areas.
• White: shows/hides all 360 radials.

A yellow LED indicator shows that a layer is on. The buttons for a hidden view are unavailable until that view is displayed again.

Eye: one press hides all lines; the next restores the default, with every line displayed except white 2D. This button does not restore any previous custom combination.
If the Antenna button has hidden them, all white lines stay hidden (2D and 3D). CAUTION: the Eye will not restore them.

Antenna: shows or hides the VOR stations and their associated layers, red and white. The blue lines are independent. While the antennas are hidden, the white 2D and 3D buttons are unavailable. The other buttons can still be operated. When you display the antennas again, the white lines return to their previous state.

Tap the buttons on the lines panel directly to change the corresponding layer.

The compass rose editor accepts whole values between −37° and +31°. In the box, type the sign and two digits, for example -10 or 05. The arrows adjust the value; the minus sign "-" is required for negative values.

Tap the rose to open the editor. Adjust the value in the box or with the arrows, which change it by 1° per tap. Wait for the processing indicator to finish so the new value is applied. Before confirmation, tapping outside the box cancels the change and keeps the last confirmed value.

Double-tapping the rose resets the variation to −24°. Restoring all mobile Preferences also sets it back to −24°.

While editing is active or being processed, the simulation may pause. The value becomes part of the preferences only once confirmed.

The Radial Window sets up an exercise for the active VOR, especially for transitions greater than 90 degrees. Choose the station on the VOR 1/VOR 2 tabs and enter INBOUND first, then CURVA (turn). The arrows increase or decrease the corresponding field. Double-check your entries.

Values can be randomized. A CURVA that fails validation may be replaced by a random value, with a message and an acceptance countdown shown in the window itself. Wait for the countdown to complete; a preview alone does not mean the values have been applied.

Tap the value box you want to edit, or use the arrows. In the first case, the device keyboard appears. The OK button confirms CURVA and applies the desired setup for the exercise.

Tap outside the window to leave editing. If you tap outside without confirming the exercise, the preview is discarded and the previous condition is kept. Do not confuse leaving the Radial Window with closing the app.

To move the window, press and hold it, then drag. Its position is kept only for the current session.

Your choices are saved automatically when you leave the app or send it to the background, with no Save button and no prompts. Data is not written on every tap. Reloading the page does not save pending choices.

The Easter Egg screen is an exception: its first display is recorded immediately, and it will not appear again, even after reloading or opening another session, until the app Preferences are restored. A single tap on RESET only restarts the flight.

Preferences are stored in the device's browser. There is no login and no syncing between devices. People using the same local profile share the last saved state. A PWA (app added to the home screen) may have separate storage, depending on the browser and system.

The following choices are saved as Preferences:

• Which instrument appears in the panel: PROA or airspeed indicator.
• Cruise speed set on the airspeed indicator (60–120 KIAS).
• Selected VOR: VOR 1 or VOR 2.
• Maximized view: 2D or 3D.
• PiP window: shown or hidden.
• Red, blue and white lines displayed in the 2D and 3D views. NOTE: these are not separate settings for each antenna.
• Eye: on or off.
• Antennas: visible or hidden.
• Magnetic variation.
• Aircraft display: airplane or circle.

Values that require confirmation are saved to the preferences only once accepted. Saving whether the PROA instrument or the airspeed indicator is displayed does not mean saving any of their numerical values.

The flight in progress is not saved, including the aircraft position, heading, CURSO, the Radial Window values, and that window's position or open state. In the next session, the Radial Window starts closed and uses its default position when opened.

A power loss or forced shutdown may lose the current session's choices. Clearing or blocking site data, private browsing and incompatible data may cause the app to use the defaults.

Flight RESET: a normal tap on the RESET button restarts the flight. It does not change the instrument display (PROA/airspeed indicator) and does not affect the six line buttons, the Eye, the Antenna, the maximized view or the PiP. Your existing preferences are not erased by this RESET.

Restore Preferences: press and hold briefly on the triangle in the lower-right corner of the RESET button; the touch area includes the space around the triangle. This opens a confirmation prompt.

The OK button restores the defaults and overwrites the local preferences. Watch for the screen flash. A message then confirms that the Preferences have been restored.

These are the restore defaults. However, if you leave the app with settings that differ from them, the choices you made will be used when you return.

Tap ajuda (help), above NAV, to open this mobile guide in a new tab. 

DIAG (diagnostics) opens environment, performance and simulation status data. It does not change your Preferences. Close it with the same button or by tapping outside the window.

The AISWEB link opens a search for AISWEB aeronautical charts in another tab. The same applies to  NAVIGRAPH, FAA and others; these are external services with their own operating and access requirements.

When you have finished reading this guide, close this tab or return to the simulator tab. This document contains only text and figures and does not affect the flight.
