Questions about navigation in M-2000C

[xjiks]

I have a few questions because I'm not sure to understand how it works:

 

- The waypoint heading and distance can only be viewed in HSI and HUD, and is not displayed on the INU ?

Like when I press DEST-0-2 and i'm in L/L mode there are some coordinates displayed on the INU but those coordinates aren't the waypoint coordinates, so what are they ?

 

- How do I display in the INU the distance and heading to the next waypoint ?

- How can I scroll between the existing waypoints to verify the coordinates of each one ?

 

I kind of manage to navigate, but i'm never sure how to use the INU to manage the navigation.

 

Any help appreciated

The INS is well explained in the manual chapter 14 page 87 you should check it out.

 

The answer to your specific question is DEST WP is your fly to WP while PREP WP is the one that is displayed on the PCN. This way you ca fly to a waypoint(DEST) while editing another one(PREP).

 

PREP: Selects the waypoint to be modified.

DEST. Selects the waypoint to be used for Navigation.

 

There is a shortcut if you want your PREP WP to be your DEST WP click the DEST 2 times and vice versa ;-)

 

If you press PREP twice, without entering a waypoint number, the DEST waypoint number will be copied to PREP.

If you press DEST twice, without entering a waypoint number, the PREP waypoint number will be copied to DEST. As long as the PREP waypoint number is higher than 00

 

If you want to understand the M-2000 INS you really should RTFM !! ;)

Additionally you can select the des wp and then double click prep to view it then move the dial to D/RLT which will display the distance in nm and bearing to the wp you have selected in prep

Does that work for all Waypoints for example does it work with custom made waypoints?

[Shadow_1stVFW]

It works for all waypoints. If you create or preload them the shortcut works.

As long as it is a way point that you have entered and saved as a des wp then yes. All you have to do then is mirror the des wp in prep and it will display. Sucks that you can't show bearing from wp instead of bearing to wp because that would be so much easier to call out for bulls reference.

The bulls ref on the VTB is bugged AFAIK and you got both on your HSI ;-)

I have been meaning to read about this. So the bullseye reference in the bottom of the radar display is distance and bearing TO the bullseye? And that's relative to the TDC cursor location also, correct? Is there a quick reference to the aircraft's bullseye location? Or is that just the readout on the PCN with relation to the bullseye WP?

Thanks for the informations, I need to go further with the manual and.... spend time on the bird to become familiar !

1. Yes.

2. If your radar is on, yes-

3. Yep. Turn the radar to stby mode and you get your bullseye data.

[Shadow_1stVFW]

Alright. Thank you very much

All is correct yes. As far as I am aware the BE is an editable WP so a quick check referencing your previous loaded wps to the BE on the f10 map should confirm which WP is your BE. For instance in blue flag wp1 was bulls and wp2 was the airfield from which you started. I'm pretty sure that on the 104th as a mirage wp1 is BE

1. Yes.

Anyone more familiar with what offset way points do? Any fancy diagrams showing what and how each one does?

Uh?

 

An offset waypoint is just that: a point whoose location is defined not by his own coordinates, but by an offset from another point coordinates.

[RAZBAM_ELMO]

So if I select a way point as offset does it use the coordinates of the way point or does it set a point wherever it wants based off of the original way point? There are three separate settings that include an offset so having a more detailed explanation or diagram for those would be good.

It's pretty simple, you can enter an offset based on lat long, or bearing and distance from your current waypoint. And you can enter an altitude for your offset point.

 

The answer you are looking for is very well described in the manual on the section about the INS system.

In PREP mode , offset is a parameter settable for any waypoint. Just select the wp for prep, rotate the switch to the offset parameters ( either lat/long difference or azimuth/distance from wp ), enter datas, validate.

To use the offset of a wp, select it as BUT, then click on BAD button. The instruments will point toward the position of the offset for selected waypoint.

Let's clarify concepts.

 

BAD (But ADditionelle/Additional Waypoint) is a waypoint that is not part of the flight plan. Instead it's position is calculated from the current waypoint's position. Thus that is why it is called an Offset Waypoint.

 

You have two ways to enter a BAD/Offset:

1. By entering the distance difference between the BAD/Offset and the current waypoint. ΔL/ΔG.

1.1 ΔL: Is the difference in kilometers from the waypoint to the BAD/Offset as measured in the North/South axis.

1.2 ΔG: Is the difference in kilometers from the waypoint to the BAD/Offset as measured in the East/West axis.

 

2. By entering the polar coordinates for the BAD/Offset. This means the bearing FROM the waypoint to the BAD/Offset and the distance, in nautical miles, to the same.

 

ΔAlt is used to indicate the altitude difference between the BAD/Offset altitude and the waypoint altitude. If the value is 0 all it means is that the BAD/Offset altitude is the same as the waypoint.

 

Now, to fly to a BAD/Offset all you have to do is just click on the BAD button in the INS. All navigation elements will start pointing towards the BAD/Offset position.

 

There is a special form of BAD/Offset navigation but this one is only enabled during a bombing run. When you click on the PI button in the PCA, the computer will flag the current waypoint as a bombing run Initial Point and the BAD/Offset as the target point. In this case you first fly to the waypoint and upon reaching it, you navigate towards the BAD/Offset where the target is located.

Makes a lot more sense now thanks Zeus. Just as an extra if you can, would it be possible to throw up some diagram overlays to show this in picture form either here or with the official manual? Just touches on both those that learn reading and learn pictures better.

Just to make sure i have all my ducks in a row, is the p/0 setting the offset distance in NM/ bearing FROM the selected waypoint or TO the selected waypoint FROM the offset waypoint?

[jojo]

From waypoint TO offset.
