Waypoints Advice

[PaulSummer]

Just starting out on the KA50  but cannot seem to work out how to change the Waypoints that have been made in the Editor  -  on the mission i was on the WP was 12   -  how can I change my WP to that number as it seemed to get to 9  but not above ?

Many thanks

@PaulSummer, the Ka-50 has two separate navigation systems, the PVI-800 and the ABRIS. The PVI is the calculator-looking keypad on the right panel in front of your autopilot buttons. The LCD moving map display to the left of the PVI is the ABRIS. The PVI-800 is your integrated navigation system in that the autopilot, HSI, and weapon systems can use the points stored in its database for flight or targeting. The ABRIS is sort of like an after-market addition that can receive inputs into the display, but cannot send any outputs to the other aircraft systems, like a computer monitor.

The PVI can only store 6 waypoints and 2 airfield points, all on the same flight plan, and only one flight plan can be stored. When you place a route in the mission editor, these points are automatically imported into your PVI in the following ways:
- If the first point is a "Takeoff" point, that will be set as "Airfield 1".
- The first 6 points that are not "Takeoff" points will be set as waypoints 1-6 in the PVI.
- If the final waypoint is set as "Landing", that will be set as "Airfield 2".
- If there are any points beyond the 6th non-"Takeoff" point that are not a "Landing" point, those points are not imported into the PVI.

The ABRIS can display dozens of waypoints on multiple flight plans, but only one flight plan is automatically created from the route made in the mission editor. In this flight plan, it will mirror the same flight plan that is automatically imported into the PVI-800, but only up to the first 6 waypoints after takeoff. If you have 12 waypoints in the mission editor, the ABRIS will have the entire flight plan entered, but only the first 6 waypoints will be entered into the PVI.

If you intend to change any waypoints on your flight plan while in the cockpit, you will need to edit the waypoint in both the PVI and the ABRIS if you want to them to match, but keep in mind the limitations of how many points the PVI can actually store when making a flight plan in the mission editor (or the cockpit). Alternatively, the PVI-800 can also store up to 10 target points as well, so you could put some of your additional points into those locations if you chose. However, these points cannot be added to the PVI's flight plan, nor will the autopilot fly to them in sequence when Route mode is engaged. The autopilot can fly to Target points in Route mode, but they will need to be manually selected as you arrive at each point successive point.

I hope this answered your question on what is possible, depending on how you were trying to edit your flight plan.

Thank you so much for the details reply , makes a lot of sense so used to flying the Av8B where I select the WP i need to go to

@Raptor9 Nice summary. Just an addition, the Airfield PVI steerpoints are only used if your heli has been 'snapped' to a FARP/Airfield somewhere. If it's just been placed ground hot/ground cold but happens to be parked on a FARP/airfield it'll count be added as a Waypoint instead.

Interestingly enough Gator on the Rise has reference to the ABRIS/KABRIS also being able to affect the autopilots, i.e. steer the airframe. So possibly-maybe some versions did integrate the ABRIS more completely than just the Nav Target Points.

To clarify, the ABRIS only displays a selected PVI Target point or a PVTz datalink point. There isn't actually any PVI or PVTz points residing in the ABRIS itself, but the ABRIS receives these locations from the PVI/PVTz memory for output on the NAV or ARC pages. So whenever you interact with the PVI-800 or PVTz-800 systems, the ABRIS is just outputting visual feedback like a computer monitor to show you which points you are selecting for Ingress mode, where they located, etc. If you were to turn the ABRIS off (like turning off your computer monitor), you could still select these points using the PVI and PVTz panels (like your keyboard and mouse), have the autopilot fly to these points, or slave the Shkval to them; it would just make it more difficult without the ABRIS to provide the visual display of the selected points in relative location.

Yeah it's only information from the PRTZ and currently active Nav TGT as you say - visually and info-able to get coords. Sounds like there *might* have been some IRL versions where doing stuff on the ABRIS, I guess selecting a map point and choose FSK2 "TO" might have guided the PVI itself.

Not that we fully need it though. Uncage Helmet sight in rought direction in the sky until it loosely intersects that spot, put on Route and/or Auto-turn and have it fly you in the direction, then set ABRIS TO if you want an ETA & distance to target ticking down. And then input coords to PVI if you really wanted to store it, preferably as a Target Point because that's just more useful for uncaging. And then forget to turn off route/autoturn all the way to the target coz you're lazy ;-)
