Air temp?

[rextar]

Hi guys looked though the forum , but cant find where the outside air temperature gauge is in cockpit?

So i know when to switch heat controls on.

[EtherealN]

By heat controls, do you mean Pitot Heat?

 

Always start it. You don't lose anything on using it when not needed. And generally speaking - you want your countermeasures in BEFORE they are needed.

[rextar]

No ethe i mean a gauge that tells me the outside air temperature in the cockpit.

[lobo]

If you switch your CDU to POSINFO page you see the OAT (outside air temp) displayed in the bottom right corner. You can switch between celsius and farenheit.

I can use metric just cant spell it...

[nomdeplume]

Curses! Sniped again.

 

So instead, I'll ask a question: is there any temperature control widget in the sim that actually has an effect on anything, other than the pitot tube heat?

[rextar]

Thx lobo great help!!

[JesseJames38]

Rextar. At anytime you start to take off flip your pitot heat on. Regardless to what the ground temp says. Because the higher you climb the colder it will get. As for the Pitot heat switch, it most likly effects other items as well such as the AOA vane.

I did not know that.

 

Thanks!

 

That is why I value reading the forums.

The Stealth Fighter, I think it is the F-117, the little stealth bomber has several as the computer flies it and it needs various pitots inputs.

 

I am sure I will be corrected by a retired F-117 jock, soon, if I am wrong. LOL!

I flew an Air-Air refuelling mission, when I was finished at altitude I dived back down to the Batumi circuit, levelled off, and with the throttles at idle waited for the speed to come back so I could extend the gear and flaps. The speed didnt seem to be coming down, suddenly I realised I was on the edge of the stall. My pitot must have been blocked! I flipped on the switch and normal service resumed shortly afterwards.

 

Good Simulation!

Ok guys ive looked on page 2 of the cdu and cant see the temp?

Check out lobo's post above. Use the right rotary to set the CDU to Position. Then it'll display OAT.

1 - Set Page Dial on AAP to POSITION.

 

2 - Temperature will be on page 1 lower right of CDU display window.

 

 

 

Alternatively, for a more accurate reading:

 

 

1 - Set Page Dial on AAP to OTHER.

 

2 - Press the SYS (System) FSK (Function Select Key) of CDU.

 

3 - Use Page Rocker Switch to select Page 2

 

4 - Select CADC

 

5 - Temp displayed on last line accurate to two decimal points.

All aircraft have several heaters, including the A-10. I'm not sure is I understood your post.

[Frederf]

He means the F-117 had multiple pitots

[mvsgas]

So does the F-16, F-18, F-15, B-2, A-10, etc

 

On the A-10 you have( guys correct me if I'm wrong)

Lift transducer, pitot-static tube and angle of attack vane

F-16

Pitot tube, AOA probes, Air data probes, Total temp, inlet strut

F-117

A,B,C,D probes

 

are all heated. This is just on the airframe side.

[Frederf]

Yeah but do those aircraft use the differential readings for FCS input?

 

And really, how many pitots does the A-10 have? I thought it just had the one.

A-10 has tree AFAIK

F-15 does not have FCS.

Heated probes

pitot static, duct pitot, total temp, and AOA.

 

The probes do not feed info to the FCS, the provide info to the Air data computer (F-16 anyway) which then feeds info to FLCC/DFLCC

[Frederf]

The F-15 does have an FCS. So the A-10 only has one pitot for airspeed. Turns out that the F-117 doesn't use different pitots for differential airspeed which I thought it might.

[Rainmaker]

FCS? What are we talking about here?

[mvsgas]

Rain, it could be my mistake. I thought he was talking about fly by wire aircraft and assume that is what he meant

K,

 

I just wondered what FCS was supposed to mean... :lol:

[Frostiken]

F-15 does not have FCS.

 

:confused:

 

F-15 does indeed have an AFCS (automatic flight controls) system which includes a sort of limited/hybrid fly-by-wire functionality.

 

Has eight probes - two AOA transmitters, two forward pitot/static probes, two total temperature probes, two duct pitot/static probes (though the static is really just a hole in the side of the inlet duct).

 

On top of AFCS the F-15 has five moving parts (three ramps, the bypass ramp, and the diffuser ramp) in each intake in order to shape the incoming air to be slow and healthy for the engines to operate at maximum performance at any speed and high AOAs. Proper ramp scheduling requires a composite input of the entire pitot/static system (well, half of it for redundancy's sake). So an iced-up duct probe can cause it to think the incoming air is traveling much slower than it really is, the ramp won't schedule properly, the engine will injest a shockwave, flameout, and the jet will flip over catch fire crash and explode. Or something.

Ha! similar incident I had online. But me and another guy were joining up after a mission to do a formation landing. I was around 500 above him and a little behind him, so I said i'd use the extra altitude=speed to catch up. This is when I noticed I was 'near' stall speed so I opened the throttle and dived down after him. I started to get a bit confused when he said he was at 250 , and I 'was' at ~170, but his plane was closing remarkably fast. Then I thought pilot tubes :idea: So I looked down to turn the heat on but forgot the guy I was closing on. Took his right wind right off. He wasn't to happy about that. :music_whistling:

It was either the battle damage I received from a triple A or the tubes were blocked as I was actually going a lot faster
