OAT gauge?

Where the fook is it???

Nothing about it in the manual, but I can't for the life of me believe that there's no outside air temperature gauge in this cockpit?

Welcome to F-5E No RadAlt either, no INS.

What do you need an OAT gauge for in the F-5E?

That's ok. TCN/ADF is fine. I can live without radar altitude as well. Besides, a tempterature gauge is pretty low (and old) tech compared to radar altitude and INS navigation.

Because there are manual anti ice switches for both the pitot tube and the engines. The temperature may be 20C on the ground, but at 25K feet the story is completely different. Pitot heater is fine, I can switch it on when my speed gauge starts to fail.
But what is the que for when to turn on the anti ice switch for the engines?

You don't really need an OAT gauge to operate the De-Icing switches. In DCS, Pitot heat should always be on and Engine De-ice can stay off because icing conditions aren't modeled (except for Pitot, that one will always get blocked without any reason).

As for real life, besides trying to stay out of icing conditions due to no wing anti ice, you should turn them on before going into icing conditions. To simplify, before entering any visible moisture (fog, clouds). And if you feel very fancy, below I guess 10 degrees C. And if you have the METAR/ATIS, you can esstimate at what altitude that can be.

And generally you turn these systems on before you get icing, not afterwards. You want to prevent ice from building up in the first place.

Yes, I know in aviation you use anti ice systems preemptive and not when the sh*t hits the fan.

I still think it's very strange that no gauge of outside temperature is in this cockpit, rather than let the pilot do an estimation based on the METAR he was given before flight, or at best the ATIS.

Pilots get more than just a METAR and ATIS to let them know of icing conditions. They also significant weather charts where icing conditions is marked and other charts/maps about weather conditions. They have manuals that tell them if they are allowed to fly into icing conditions and how to behave if they are in icing conditions. They also know if their aircraft is certified for flight into known icing or not, making the decision process even easier.

Outside Air Temperature is also a bit useless if you have a fast aircraft like the F-5. Depending on your speed, it will show you a different temperature than what the still air actually is, which may lead to false assumptions.

Fair enough. But instead of OAT, it could be SAT, which is basically the same thing apart from that it measures static air.
