The bobbing up and down in pitch as if bouncing on a spring, that I've noticed in a couple of videos now, looks abit weird though.

 

That's just me flying poorly. Pilot induced oscillations, as it were.

 

Not something that happens with a neutral stick.

Ok, so it does not happen after centering the stick following a pull or push?

 

I'm asking because I noticed it in a couple of videos now so I became abit worried.

Oh and you can sucker the LNS dev pilots into a sharp climbing turn at the merge and demolish their energy...but thats another story... :P

I cannot see anything to worry about, the close formations at that speed were retained during the grudge match stream. That's all you need to know.

Just a quick question. I know this is an SF37 but I'm curious about the two pods around the external fuel tank in this photo. What are they? Camera pods?

Yes they are Recce pods

they are named MSK Vänster (Vänster = Left) and MSK Höger (Höger = Right)

they are used for Night Recce.

MSK Vänster (left Pod) has 3 Cameras with 76mm optic + a Flash Unit,

The cameras are mounted to cover a 120 degree area.

 

The Flash unit on the Left pod only lights up the 60 degrees to the left inside the area covered by the cameras but the second pod (MSK Höger) contains only a flash unit in order to cover the 60 degrees to the right so together they cover the entire 120 degree area covered by the Cameras.

 

The Cameras/Flash Units work in the shortwave IR range that is immediately outside the visible spectrum so the flash from the flash units is not visible to the human eye.

This System was used for Photography from a low altitude.

 

 

 

the SH-37 also carried camera pods of different types including those just mentioned

as it lacked the nose camera set as it was equipped with a radar instead.

 

Here are Examples of a SH 37 with Camera Pods.

Saab_SH37_Viggen,_Sweden_-_Air_Force_AN1117576.jpg

 

0804174.jpg?v=v40

 

 

 

The SH 37 could carry the same MSK Vänster / MSK Höger pods as the SF 37 but also had a dedicated camera pod fixed to the right side of the body named KaK with a 600 mm focal length that was designed for long range photography against targets such as Ships and harbors the.

 

That Camera had to be removed in order to Carry the Night Recce pods.

 

On the Second Picture it looks like its mounted with both the KAK Camera as well as the MSK Vänster Pod but im not sure if that was an operational loadout

(since only have of the area covered by the Cameras in the MSK Pod would be correctly lit without the other MSK Pod)

or if its simply that they mounted it for Display purposes.

 

On a side note.

These two pictures surprised me at first as i did not know that F 15 had operated the SH 37 but it seems that during the 90s when the second division was reformed and brought up to full combat strenght it included both attack and Recce aircraft (from other Wings had had been retired) and not with just AJ/AJS aircraft as i had assumed earlier

but looking into Viggen Serial number lists confirms that F 15 did indeed fly some SH 37 and SF 37s

 

And if that list is correct then the aircraft on these two picture (15-81) crashed in an accident a few months after these pictures were taken.

(The second picture was taken at RIAT on 21 July 1996 and it crashed in October 16 1996 with the pilot dying in the accident)

It should be a Night photography pod on the left which contained IR film cameras while the one on the right side (from the aircraft POV) is a flash pod for low light photography illumination.

I think roadside speed cameras would work well for that purpose (at least if they were radar based and not based on sensors in the road as is the norm these days).

I'm faily sure swedish speed cameras are radar based. :P

Not a Viggen and it's on a trailer but... :D

The Viggen's autothrottle feature is called automatisk fartkontroll (AFK). If you like me are twelve years old mentally, well...

Is the AJS37 version of the Viggen able to deploy countermeasures?

Modules: A10C, AV8, M2000C, AJS-37, MiG-21, MiG-19, MiG-15, F86F, F5E, F14A/B, F16C, F18C, P51, P47, Spitfire IX, Bf109K, Fw190-D, UH-1, Ka-50, SA342 Gazelle, Mi8, Christian Eagle II, CA, FC3

Yes, but they're carried in pods that can only be mounted on the inner underwing pylons, so you can't carry certain weapons (mainly the rb 04 and rb 15 anti-ship missiles) and countermeasures at the same time. In reality, one or two aircraft in a flight of four would carry countermeasures.

 

There's both a flare/chaff pod and an ECM jamming one.

Anyone got a diagram of the stick and throttle controls (as well as the rb05 stick) so we can plan out our hotas setup?

I'm pretty sure someone (BravoYankee4, I think?) translated an entire cockpit layout diagram. It's probably around, eh, 350 or so pages back in this thread... ;V

 

edit: wasn't far off, here, then corrections and updates here and on the following pages. But it's not that detailed with regards to the sticks and throttle. By the way, there are actually three sticks - radar, rb 05 and the plain ol' control stick.

I did the throttle handle quick and dirty, might do the others later.

#1 is a lockout latch that prevents you from moving the throttle back past the ground idle detent - pull it up and move the throttle handle all the way back to turn the engine off and close the high pressure fuel cocks.

 

#4 is a countermeasures "panic button" for the flare/chaff pod (KB). Press and hold to dispense flares and/or chaff continuously (one flare every three seconds and/or chaff in a 2s dispense, 2.5s pause pattern). Getting flares, chaff or both depends on what the three-way dispense type switch on the KB control panel located just under the canopy edge on the left side of the cockpit is set to - R ("remsor") for chaff, F ("facklor") for flares, and R+F for both.

Awesome thanks man! Autothrottle huh? Interesting.

 

EDIT: Can someone briefly explain the HUD while were at it. Looking at the videos it seems very different then anything else I've seen on US and Russian planes.

The autothrottle is fairly simplistic and mainly useful for landing - if you enable it with the gear up it simply attempts to maintain a reference speed of 550 km/h IAS, and you can't change that. With gear down though it does try to help you maintain proper glideslope.

 

The HUD is a pretty big topic. The nav mode is fairly simple but there's a whole bunch of different modes for different weapons that would require a long-ish writeup that I can't be bothered to do right now. For the basics, though, see here and I guess here.

 

Moving on, the main stick is fairly straightforward:

 

h6qPowP.png

 

49 is essentially the master arm switch - there are no other weapons arm/safe controls in the cabin. It also has a bunch of side effects for different weapons. For example, the protective nose cover on the rb 75 (Maverick) is jettisoned and the TV seeker is started when you arm while having rb 75 selected on the weapons panel, so you need to arm well before you see the target so you can adjust the brightness/contrast on the scope, while on the other hand if you're firing rockets you only want to unsafe when you have the aim point established on the target because that starts the lead calculations, and so on.

 

51 is a weirdly underused button considering its highly prominent placing - it's used for calibrating the course gyro while on the runway and for updating reference altitude for the current waypoint in the nav system. While the HUD is in the low altitude (declutter) mode you can also toggle a few different display modes with this button (course scale visible or not, for example).

 

52 triggers saving of a bunch of important variables in the flight data recorder (they're saved periodically anyway but this forces a save right now). It was supposed to be used in case of in flight problems and/or minor emergencies for troubleshooting on the ground, and I can't see that being all that useful in DCS.

 

As far as I know the trigger only has one stage - there is no intermediate detent.
