Positioning the Aircraft at the Location

You can either fly the aircraft to a point along your your route, or use the slew mode. Continued use has found that flying the aircraft to the exact place along the tour route makes it easier and more precise.   Once the aircraft is at the location, place ths aircraft in the PAUSE MODE by pressing the "P" key on your keyboard, or by saying, "Pause the simulator".

Creating an AtLocation Event

Minimise your flight simulator.   Click on the Tour Designer button.   Once the designer appears, click on the AtLocation item in the Trigger event on ? and... list to the left...

and enter your narration.   Test your narration by clicking on the Speak Phrase button.   You can stop the system from speaking by pressing the Stop Speaking button.

Aircraft's Geo Location

You will see that the aircraft's current Latitude and Longitude are displayed at the bottom of the editing box.   In the above image, you will note that the Latitude is 48 Degrees, 20 Minutes and 40.6850 Seconds... written, 48* 20' 40.6850''. The current Longitude is -120 Degrees, 43 Minutes and 9.3184 Seconds... written as, -120 43' 9.3184''.

When you click on the AtLocation function, the IYP Tour Designer takes the aircraft's current Latitude and Longitude and uses this information to trigger an event whenever the aircraft comes within the specified nautical miles of the specified point in space.

In the case of Figure 2 below, the aircraft is at point A and it is 1 nautical mile to point B; the center of an imaginary circle.

Aircraft's Geo Attack Angles

Referring to Figure 3 below, you will note the expression Current Quantized Bearing.   This simply means that the aircraft's current bearing is brought to the closest of 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330 or 360 degrees respectively.   For the purposes of explanation, if the aircraft's current bearing is 68 degrees, the Tour Designer will use the Current Quantized Bearing of 60 degrees, since it is the closer to 60 than any other degree.   This value is automatically loaded for you, however, you can select a different bearing if you so desire.

The degrees "Left of" and "Right of" the Current Quantized Bearing, defines the "window" the aircraft must fly through in order to activate the event.   Again, assuming a Current Quantized Bearing of 60 degrees, with the "Left of" and "Right of" bearing degrees set to 30 degrees, it specifiies that the aircraft needs to enter this location at a bearing between 30 and 90 degrees in order to trigger the event.   i.e., if the aircraft enters the area at a bearing of 180 degrees, the event will not trigger.   Similarly, if the "Left of" and "Right of" bearing degrees were set to the maximum of 90 degrees, it would specify that the aircraft needs to enter the location at a bearing between 330 and 150 degrees in order to trigger the event. i.e., 60 - 90 = 330 degrees; 60 + 90 = 150 degrees.

Aircraft's Altitude

The variable defines that the aircraft must be both, above a certain altitude and below a certain altitude, in order to trigger the event.   The need for this facility is best described with an example.

Let's assume that you are at an airfield where the altitude is 2,000 feet.   Your tour has the simmer taxiing to runway 31 with a taxiway bearing of 130, taking off from runway 31, climbing to 4,000 feet, then looping back over the runway at a bearing of 130. If you want to trigger an event while the aircraft is flying over the runway, you certainly do not want the event being triggered during taxi.   Therefore, you can specify that the event will fire when the aircraft is bearing 130, BUT... at an ALTITUDE GREATER THAN 3,000 feet and, for example, BELOW 40,000 feet.
