WOW! What an incredible source of adrenaline!

[JEFX]

I was trying to obliterate a convoy of russian tanks but I got peppered so badly by their bullets in my rocket runs that at some point, not only the HUD and CICU, etc stopped working but also the ACTUAL ANALOG instruments!!! I had nothing left that could give me a clue about my airspeed and for my altitude, I found that I still could get a radar altitude with the switch to normal!

 

I finally landed totally by ear... knowing that I must be a bit fast when my flaps retracted (the hydraulic systems were still ok...)

 

What an excitement!

 

WOW

 

When I taxied, I looked at my aircraft and it was totally covered with bullet holes.

 

THANKS ED, this is the best SIM ever!

100% correct JEFX.

 

now the only thing we need is more time to fly

Now I wonder what's the flaps logic to follow in such case, as mentioned above-ie: loosing IAS indicator. They do extend to MVR or DN position below certain speed obtained from... IAS gauge?

Truest statement everrrrrrr :thumbup::thumbup::thumbup:

The AoA indicator should still work, just reduce speed till you get a circle on the indexer. If that is also not working then seat of your pants will have to do. Runways are pretty long so stopping in time should not be a problem.

I'm pretty sure this is a load relieve function. So the flaps will retract to the next smaller setting when the aerodynamic load on them gets above a certain threshold. This equals a certain IAS, hence the reference for the pilot, but this says nothing about the IAS indicator still working or the computer providing data to the IAS indicator still working.

If I am wrong feel free to clarify.

 

EDIT: I just realised I might have read you wrong; did you mean they will retract above a certain speed automatically or extend down automatically below a certain speed?

I'll forward to the devs, could be a bug.

You switched on the PITOT HEAT?

If you fly in hight altetude your sensors of the analog instruments freezes.

I never saw a damaged analog instrument by a bullet.

Seen it plenty. The pitot tube is somewhere on the right wing it seems since whenever I lost half that wing or took severe damage there the analog instrument will goto zero.

Really? cool! Never noticed that.

Both. If you won't retract the flaps yourself they retract above 185? knots, but if you slow below this speed, they deploy to their previous position.

your standby Instruments are on the Battery bus (this is simplified i know) to ensure power in case the ac supply is lost due to engine driven generators (damage or failure). But if you also have damage that kills the battery or electric bus from the battery you will loose the instruments.

I meant exdend [down] automatically while switch already positioned and decreasing speed over their operational speed. Their relay needs to have a source to prevent damage over some speed.

Anyway, I was guessing load on them too, but taking into accout design to make such frame as simple/reliable I assumed that would unnesec. made construction more complex rather than having an IAS direct feed. I MIGHT BE WRONG though. Need to do some research over internet to find out answer [or kindly await more educated simmer/pilot to clarify].

That too maybe. You do need a pitot tube somewhere on the aircraft too. So far in my experience, when there is damage to my right wing I loose speed indication on the steam gauges. Can anyone confirm the location of the pitot tube on the real jet? Cali?

[Cueball]

WTF!!!! A great story and no screenshots. Sounds like you had a blast.

[Geskes]

Nice story,

 

something for next time:

 

If your analog altimeter is failing because of electronic system loss you can switch it to pneumatic mode by flipping the switch on its bottom right.

 

I got this tip from someone on this forum who's name I do not recall and I have already used it countless times since :)

 

Airspeed indicator doesnt have such a thing (obviously) but if you have anything operational indicating range to airbase, you can count the seconds it takes to do a nautical mile, say x and then do 3600 divided by the number of seconds. (Since 1 knot = 1 nm per hour, an hour has 3600 seconds). So say it takes 10 seconds, you do 1/10 times 3600 or 3600/10 = 360 knots. For landing speed it should be between 25 - 30 seconds for a nautical mile = speed between 120 and 144. Of course when you are flying at an angle you'd officially have to calculate the long side of the triangle, since ground travel of 1nm doesnt equal 1nm in air when you are descending/ascending but just subtracting a couple of seconds from your count is equal.

 

Yes far sought but its getting late here and I was trying to think of a way to approximate airspeed in such situation, my brain farted this. Hey, its better then nothing at all. :D

[Yskonyn]

This only works though if your pitot tube is intact. I believe his right wing was shot up. ;)

Doesnt the hog have a pitot static airspeed indicator as stby instrument? That would mean its pneumatic as well, using the difference between static pressure and pitot pressure to display airspeed.

I cant check right now.

[AMVI_Sparrow]

Amen dude ;)

 

LOL :megalol:

[JEFX]

Sorry guys I didnt take any Screenies, I was so into it... (and it was late...) I like the pneumatic switch trick, will try it some other time! No I couldnt relate to a distance to airbase, my hud was non-operational anymore. Yes pitot heat had been on.

 

My best airspeed indicator was the flaps thing : yes since the Hydraulic systems were still working, I was able to put 7 degrees of flap when I was quite slow, but whenever I would go over 185 KIAS, I knew they would retract and they did, so that gave me a visual cue about how fast 185 KIAS was...

 

Great fun (Yes, Amen!)

[Crosser]

I've had to turn the APU on mid-flight due to total loss of both engines..battery wasn't cutting it. Hud and everything came back, minus hyrdos but I'd already gone to manual reversion. That was a bad day but I managed to land on a road gear intact.
