BravoYankee4 Posted December 13, 2015 Posted December 13, 2015 The autopilot (SA 06, where SA stands for "styrautomat") is capable of two modes: - Attitude hold/course hold: press the button ATT to activate. If pitch angle is <60° and bank angle is >7° and <66°, maintains both as they are. If bank angle is <7°, the aircraft instead enters course hold mode and maintains current course at neutral bank. While in this mode, autopilot controlled turns can be commanded by using the trim button on the stick. The bank angle used by the autopilot depends on airspeed and ranges from 10° at 200 km/h IAS to 45° at 800 km/h IAS. You can still control the aircraft in both pitch and roll axis while attitude hold/course hold is active, you just need to use some physical force to get the stick to move. If you do this and stay within the limits above, the aircraft will hold your new attitude when you let go of the stick. If you exceed the limits the autopilot will disconnect and enter a passive mode where it'll automatically reactivate once you get back within the limits. - Altitude hold: press button HÖJD to activate. Works exactly like the previous mode but the aircraft will also maintain current barometric altitude. Adjusting the altitude is done with the trim button on the stick. If you activate autothrottle with the landing gear in, it'll try to maintain 550 km/h IAS. You can't adjust that. It's really only intended for landing. tl;dr: if you activate the autopilot in a reasonable situation and let go of the stick, the plane will keep doing what it's doing. If you move the stick and enter some new reasonable situation that you like better, the plane will keep doing that instead. Quite reasonable, I think. It can't follow waypoint routes for you, though. Thanks. But what avout the "SPAK" indicator/button - isn't there a third mode?
renhanxue Posted December 13, 2015 Posted December 13, 2015 Thanks. But what avout the "SPAK" indicator/button - isn't there a third mode? SPAK (dämpning/spakkraftstyrning) is just oscillation dampening (in all three axes), artificial stick forces and a bit of stabilization in the transonic area. It's normally always on. It's a thing the autopilot does but I don't think it counts as a "real" autopilot mode.

It was really bugging me not understanding what SPAK did, and it's great to know what the logic of the other modes is. [sIGPIC][/sIGPIC]

TomCatMucDe Posted December 14, 2015 Posted December 14, 2015 I just want to give a thumb up to the swedes in this thread for their friendly attitude and helpful contributions to demystify the Viggen.
OnlyforDCS Posted December 14, 2015 Posted December 14, 2015 That's a beautiful video. I have to admit Ive not even heard of the Viggen until the speculation started to go around here on these boards, but why some people consider that plane ugly is truly beyond me. I think it looks and flies beautifully...

BravoYankee4 Posted December 14, 2015 Posted December 14, 2015 Anyone (renhanxue?) that can elaborate about the following indicators? * Destinationsindikator (red) - What kind of destination? * Avståndsindikator (yellow) - Distance to what? Target (specific weapon?) or navigation?

I have to admit Ive not even heard of the Viggen until the speculation started to go around here on these boards, but why some people consider that plane ugly is truly beyond me. I think it looks and flies beautifully... The Viggen was my preferred aircraft since childhood when it comes to looks and beauty of design. Even a year ago I was begging Leatherneck for such a gift, because commercially I only see it possible on DCS. I'm sure there's no way I could be dissapointed.

Teo Posted December 14, 2015 Posted December 14, 2015 Anyone (renhanxue?) that can elaborate about the following indicators? * Destinationsindikator (red) - What kind of destination? * Avståndsindikator (yellow) - Distance to what? Target (specific weapon?) or navigation? IIRC the "destinationsindikator" displays current waypoint/target point name: ex "B4" for "brytpunkt"/waypoint 4, and the "avståndsindikator" displays distance to selected waypoint.
BravoYankee4 Posted December 14, 2015 Posted December 14, 2015 A little note about the afterburner. It is a three stage afterburner and the different stages are indicated here (three white lights). The throttle has a very distinct detent when going over from normal to afterburner by the way.
Kilrah Posted December 14, 2015 Posted December 14, 2015 Are you sure about the white lights? I thought it would display stages as 1, 2, 3, where 3 is full afterburner.

JawsMa Posted December 14, 2015 Posted December 14, 2015 (edited) Dogfight? Beautiful pictures of a beautiful aircraft, but Dogfight is an overstatement. All I see in that vid is 10 sec of poorly performed defensive ACM. When this swedish tiger is released, I´l give you some Dogfightvids to watch. :-) Cant wait! Cheers! /Jaws Edited December 14, 2015 by JawsMa

Yes, I forgot about the numbers. Please correct med if I'm wrong with the other details also - since my memory might fail me...

T0x1s Posted December 14, 2015 Posted December 14, 2015 I've seen some guys here saying that the Viggen will be out before the F-14 Is there any source on that?
RaXha Posted December 14, 2015 Posted December 14, 2015 I've seen some guys here saying that the Viggen will be out before the F-14 Is there any source on that? Cobra has mentioned in the past that the two unannounced aircraft that they have in development were further along in development than the F-14 is, and that they would be released by the end of the year. The last part is probably no longer true though since the announcement of the modules was planned a few months ago and Cobra being sick for a long period of time among other things has pushed it back a bit. But if they are to be believed they are a lot closer to release than the F-14. :-) :pilotfly:
OnlyforDCS Posted December 14, 2015 Posted December 14, 2015 Yes thats the way I understand it too. Both aircraft will be available before the F14.

CoBlue Posted December 14, 2015 Posted December 14, 2015 Anyone (renhanxue?) that can elaborate about the following indicators? Here's a blogg (in Swedish) by an retired Viggen pilot, were he explains some navigation: http://chefsingenjoren.blogspot.se/2011/01/en-talig-tant.html And his general experiences about Viggen:http://chefsingenjoren.blogspot.se/2011/02/i-kanten-av-envelopen.html :) i7 8700k@4.7, 1080ti, DDR4 32GB, 2x SSD , HD 2TB, W10, ASUS 27", TrackIr5, TMWH, X-56, GProR.

Gh0st007 Posted December 14, 2015 Posted December 14, 2015 The SAAB is awesome aircraft! I'll buy it for sure! but that's me. I hope to see a future in DCS for this aircraft My system specification i9 13900000K/Game board - 64GB of random access memory / Galax 7090/ ViewSonic Elite XG320Q 32 Screen of monitor/ VPC Collective - VPC Sharka50 Grip / Trackir 5/ TPR/ Orion2 F/A-18 Throttle/VPC WarBRD Base/ Hornet grip/F-16 grip/ and most of all a ham sandwich.
BravoYankee4 Posted December 14, 2015 Posted December 14, 2015 I just love this story from the blogg previously linked to: For the Viggen we had permission to fly as low as 30 meter over land and 20 meter over sea. Previously it was 20m and 10m, but after an incident where a pilot cut the phone wires between two islands (at 8 meters height) and forced to land with some hundred meters of wire hanging from the fuel tank, it was raised to the new levels.

Wow, just wow Thanks for the translation. And lo, Reverend Vegas did say "Take forth unto the infidel the mighty GAU 8 and expend its holy 30MM so that freedom will be brung upon them who knoweth not the joys of BBBBBBBRRRRRRRRRRRRRRRRRRRRTTTTTTTTTT" "Amen"
BravoYankee4 Posted December 14, 2015 Posted December 14, 2015 There was also another story about an old lady calling the local air force commander when a couple of Viggens blew off the roof tiles at her little cabin. Not complaining, just stating the fact. Back in the days the Swedish people had a very positive attitude to the armed forces and the defense of the country. Today unfortunately people have started to question why we should have any armed forces what so ever... and complaining about inconvenience and being disturbed as soon as they see a green vehicle or a person in uniform... 1
