Clear picture in this article from the top of the ridge down at the crash site. I did post the picture itself but it disappeared.
Crash: Sukhoi SU95 over Indonesia on May 9th 2012, aircraft impacted mountain

I am FED UP with the constant allusions and sarcastic remarks by some here ( mostly the Brits) regarding the quality of the engineering, construction,training and operation of the Sukhoi in particular and Russia in general.

Fact is that Russia has always had and has a very Solid aviation industry with designs that have Always greatly surpassed any crap that the UK. ever produced.
After Russia was declared the most dangerous country for aviation, and after watching that Aeroflot Airbus depart with settled snow on the wing, our views on Russia are justified.

That being said, I was quite impressed with the Sukhoi.

Guys, calm down your chauvinistic daemons, and stick to the topic, PLEASE!

I fear that the Spirit of the Costa Concordia is alive and well.
Aircraft and ships do not always travel in the direction in which they are heading.

Indonesia National Air Carrier Association (INACA) secretary general Tengku Burhanuddin said the crash of would not affect local demand for such aircraft.
I agree. The motivating factor here is purely low cost travel.

I think it's a good design and Sukhoi have a lot of military aircraft experience they can draw on , if they get the tech support and spares right this could be THE next small intercity jet.



I haven't had anything to do with Sukhois but the Antonov's I have dealt with are very clever robust and simple to maintain designs , if Sukhoi has a similar design philosophy that's what we need in Asia.

Anyone know what the short field performance is like ? Can it operate out of an 1,100 to 1,300 metre runway ?

I've seen clouds hover over mountains in such a way that the terrain emerging below the cloud deck could be mistaken, on quick glance, for the horizon line. It's possible they were sightseeing and mistook clouds lowering over the peaks as the actual ridge line.

The clouds in that whole range of volcanoes and mountains between Jakarta and Bandung can form from nowhere before your eyes. The storms over those mountains are something else , frightening

It's a little bit of Papua or PNG in Jakarta's back yard.

Gunung Salak has claimed I think 5 or 6 aircraft in the last 10 years and those were being flown by local pilots that knew the area.

Ok similar to a 737, thanks

Is it unusual that there is no obvious evidence of a fire at the crash site?

V1 VR V2 11th May 2012 11:22

If you look at the picture of the impact the trees on the ridge and around the side are a different colour to the others. This may be caused by heat of fire from the impact causing them to turn brown (charred)

Does anybody know what kind of equipment this A/C has on board? GPWS, GPS, TCAS or any other relevant instrumentation.

T2CAS - Garuda 152 revisited
 
The Sukhoi SJ100 has T2CAS fitted, which allegedly offers greater protection to CFIT.

A good point was made earlier about regional data feeds to the EGPWS. Common and commercial sense suggests a Demo aircraft would have all its tricks on show to potential purchasers.

So, why did the T2CAS not alert the Test Pilots to the impending ridge?

Recall Garuda 152 A300 CFIT where the GPWS functionality was called into question.

Superjet International
 
Forced to emerge from lurking by too much inaccuracy, and prejudice against Russian aircraft. This plane is not very Russian at all, as some posters have indicated above, with components from Boeing and many other Western companies.

Superjet International is a joint venture in which the Italian company Alenia Aeronautica (part of the state-owned Finmeccanica group) owns 51%.

The President & Chairman, and also the CEO, are Italian.

The HQ is in Venice (Italy, to avoid equivocation).

Probably because the ridge didn't have a transponder! Having seen this level of muppetry on the first page I've looked at, I think I'll leave again :ugh::ugh:

212man,

Before you give yourself a headache I suggest you google T2CAS, you may learn something like I have.

Probably best you do leave...:ugh:

TCAS: Terrain and Traffic Collision Avoidance System - Thales

Maybe you should look up the acronym.

TCAS is an integrated TCAS plus TAWS system by Thales. So it should have warned of impending terrain collision, if (a) it was not disabled, (b) it was loaded with maps of the region, (c) the maps of the region were accurate and (d) it was receiving accurate GPS coordinates.

Neither of which we know for certain just now.

Summarizing from russian pprune (forumavia.ru):
1. Poor preflight preparation (route and airfield charts, MSA etc).
2. Probably the terrain database had not been uploaded.
3. Probably the EGPWS had been turned off for this flight.
4. Test pilot - not much experienced in high terrain flights.

Here are pictures of another blogger from the first demo-flight that day:
