Zeus67 Posted July 6, 2016 Posted July 6, 2016 I am curious about the currently not implemented NAV modes... TOP and RD - Will they be implemented ? - What are the specificities of these modes ? What usage ? 1. Yes, they will. 2. TOP and RD are tied to the RD/TD option in the INS. RD = Roue Désirée (Desired Route). Normally waypoint navigation is Direct-To between each waypoint. What RD does is create an indirect route to the next waypoint. RD is the bearing angle you must follow until the INS commands you to make a turn to the next waypoint. TOP = TD = Temps Désirée (Desired Time). TD indicates how long do you want your flight time to be between each waypoint. A HUD symbol will appear telling you to go faster or slower so you reach the waypoint after flying the specified travel time. Despite the fact that both RD and TD share the same parameter position, they are independent modes. "Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning." "The three most dangerous things in the world are a programmer with a soldering iron, a hardware type with a program patch and a user with an idea."
sedenion Posted July 6, 2016 Author Posted July 6, 2016 RD is the bearing angle you must follow until the INS commands you to make a turn to the next waypoint. To verify if i well understand: The default Nav mode: - simply indicate you the heading to the selected WP (curr position -> selected WP) RD mode: - indicate you how to follow the line/path between two WP (previous WP -> selected WP) ?
jojo Posted July 6, 2016 Posted July 6, 2016 Not exactly. In RD you select the course to WP. But yes, the most likely is to set the course between 2 WP. In this case, if you go off track, the system bring you back on the line instead of just guiding you directly to next WP. But you can also choose: I want to arrive on WP 12 in 5 minutes (TOP) and heading 318 (RD). That heading don't have to be the one from WP 11. You choose. Mirage fanatic !

Ok, we also can combine TOP and RD... thanks. So the current implemented nav mod is in fact a kind of RD mode or just the real "default mode" ?
jojo Posted July 6, 2016 Posted July 6, 2016 I'm not aware that RD or TOP are active yet. The current mode is direct "go to", which is default mode. Mirage fanatic !

Azrayen Posted July 7, 2016 Posted July 7, 2016 Ok, we also can combine TOP and RD... thanks. Mhmm... would like that to be double checked before taking it for granted. :book: So the current implemented nav mod is in fact a kind of RD mode Not at all. What made you think such a thing?
sedenion Posted July 7, 2016 Author Posted July 7, 2016 (edited) Not at all. What made you think such a thing? I just ask... jojo says RD mode allow to choose between direct heading (what current default nav mode does) and path follow (that's what i understand)... Edited July 7, 2016 by sedenion
ZHeN Posted July 7, 2016 Posted July 7, 2016 I don't get it. Can anyone explain me on an example? So, for instance, I have WP 11 & WP 12 and a direct line between them - the default route. So I've passed WP 11 and flew away from the line to do some search job or engage bandits (doesn't matter), but my next objective on WP 12 is a ground target, so I need to approach it strictly by default route, that's been set up in the beginning. Will I have to press RD after I did my stuff @ WP 11 to get back on the line between WP11&12? [sIGPIC][/sIGPIC]
jojo Posted July 7, 2016 Posted July 7, 2016 (edited) Yes that's it. But for that to work, you will need to have set the arrival course on WP 12 with RD/ TD in PCN. It's not a line automatically set between WP. It's an arrival course attached to each WP, and you need to fill it. Well maybe it would be better if it was loaded by default with course between WP. But you need to understand what you do if you edit yourself. Edited July 7, 2016 by jojo Mirage fanatic !

But you need to understand what you do if you edit yourself. Ok Lets precise: Default Nav: - direct heading to selected WP according current position (curr position -> Selected WP) RD: - heading & path follow depending selected course type (in PCN) for this WP, can be a straight line WP1->WP2, or any calculated curve around WP. ( in other words: RD allows other curve interpolation types than the linear one between WPs ) That's it ? Edited July 7, 2016 by sedenion
jojo Posted July 7, 2016 Posted July 7, 2016 RD = any straight line to selected WP. The straight line can come from previous WP or not... Mirage fanatic !

ZHeN Posted July 7, 2016 Posted July 7, 2016 hmm.. what if I don't know the arrival course ? ... :/ [sIGPIC][/sIGPIC]
jojo Posted July 7, 2016 Posted July 7, 2016 hmm.. what if I don't know the arrival course ? ... :/ Don't use RD :D It's an option, not mandatory. Mirage fanatic !

Chrinik Posted July 7, 2016 Posted July 7, 2016 Okay, this is giving much confusion to people...say the target waypoint is a Building on the end of a Road. The road is going 240 and you are approaching from 180, but you need to (for whatever reason) approach over the road. So you set your RD for that waypoint to 240 and it will guide you so you will approach the waypoint from that direction.

ZHeN Posted July 7, 2016 Posted July 7, 2016 what if I'm coming from 180 but I need 0 ? how will it make me approach from 0 ? [sIGPIC][/sIGPIC]
Azrayen Posted July 7, 2016 Posted July 7, 2016 (edited) Chrinik is correct. Sedenion, I don't know what's curve interpolation types (and I don't need/want to). Let's be precise indeed, but also simple: - default nav mode is: direct to DEST but. Always. That's the "little house" in the HUD. If you're flying away from the DEST but, the house should be upside down (not yet implemented). - RD nav mode is: pilot defines a heading he wants to follow to arrive to the but (WPT). The system computes needed variables, then provides a guidance solution that the pilot will follow to rejoin the needed course. Hop: Edited July 7, 2016 by Azrayen

The pilot can choose the approach/arival heading to the WP... this heading can be whatever we want, the one corresponding to WP1->WP2 line, or any other. (i was on a totally other paradigm ) Edited July 7, 2016 by sedenion

Hop: What came to my mind is that we could use the RD when delivering CAS to a JTAC which states a 9-line in order to match the "final attack headings" restriction for instance. Right ? This could be used aswell to avoid specific areas full of muds or to remain into a specific airspace. Edited July 23, 2016 by Sacha [sIGPIC][/sIGPIC]
