Nav system

Hi,

Is it possible to program way points in the nav system, as well as through the data cartridge?

I looked in the manual, but it wasn't clear if this was possible, or how to do it?

Yes, you can input new waypoints (or alter existing ones) by using the keypad of the aircraft's computer. Here is a good tutorial on that point:

You can program a flightplan in the missuon editor aswell as manually in-game.

The missuon editor flightplan is saved in your default data catridge. There are different data catridge that offer automatically created routes to close targets (feature useable but still under development).

The manual programming basically is inputting Long/Lat coords (LOLA) or automatically created reference numbers.

Great feature!

Thanks for the video.

Beyond that you optionally can enter time on target and desired speed per waypoint. For target waypoints you can define popup points (per offset like 3km to 320 deg). Also you can enter two boundary lines per waypoint. Latter may help if you plan to enter a waypoint only from a certain direction as the HUD will display those lines as visual aid.

However,in most cases you will probably be fine with just entering waypoint coordinates.

And for weapon deploymentdont forgrt to compute the QFE a the targets location (you need QNF and target height). There are calculators online, theformula is quite easy though. John (the guy of the linked video) has a video about Viggen and QFE computation.

I was reading about that yesterday. I'm starting to understand, and now trying to actually do it.

What is the significance of the altitude selector? You can switch between radio and barometric altitude. What does this affect?

It only affects the readout on your HUD (the "digital altitude" value usually displayed to the left).

For baro the value is the same as on your altimeter (computed using QFE setting, which is different from location to location). The altimeter readout therefore not changes when terrain changes, you would need to update the QFE for that new position for a correct altitude value.

For radio it will display what the radio laser reads (if you are flying low enough, maybe below 500,dunno but manual knows)

That is a small laser pointing straight down from your aircraft. It measures the actual distance to the ground. This readout therefore is "live", but you need to turn on the device (which it is by default).

Obviously the radio value is only useable when flying wings level, not when turning. Due to the laser always pointing down relatively to the aircraft. So in a slight turn the actual measured distance increases as the laser is not pointing straight down to the ground anymore.

Note that in order to get low altitude warnings you dont need to set to radio, it is enough to turn on the device. The setting really only affects the HUD readout.

Weapon computation like rockets or guns by the way always uses barometric no matter what you set. (unless you use a weapon mode like radar ranging, which uses the ground radar for distance measurement).

In most situations you probably want the radio setting for an actual altitude readout when flying low. For example to hold an altitude of 20m though the terrain changes.

Im not sure why the startup procedure says "set to baro", maybe there is an issue im not aware of. Like with gyros getting damaged when turned on at takeoff or landing.
