Red Markings on AOA indicator


Snappy

Recommended Posts

Hi,

 

 

does anyone know the reason, why the 15 degree value on the AOA

marker is emphasized with the thick red line?

The DCS manual says nothing on this and the english Manual from the German Air Force

Mig-29 doesn't it explain it either in detail.

 

It is not the maximum AOA , at least not in absolute sense.

 

 

I'm not sure,it could be either optimum AOA (with the best lift to drag ratio) or the AOA

limit with LEF retracted , but I don't know why they would mark that, as normally they should have extended automatically before that during maneuvering

and should not be lmiting.

 

 

Does anybody have an idea? Or can check the russian manual?

 

 

 

Kind regards,

 

Snappy

15° AOA is mention several times in the manuals.

Some examples from the 1F-MIG29-1;

Page 1-67, 1-67B, 5-13, 6-11, 6-12

- 15° AOA is critical for AOA/G computer low and high value.

- If no LEF extension, 15° AOA becomes the limit.

- Above 15° AOA, stick force reduce drastically creating an inherent tendency of uncomanded pitch up at around 18° AOA.

 

More can be found in the manual.

To whom it may concern,

I am an idiot, unfortunately for the world, I have a internet connection and a fondness for beer....apologies for that.

Thank you for you patience.

 

 

Many people don't want the truth, they want constant reassurance that whatever misconception/fallacies they believe in are true..

In all aircraft instruments, regardless of aircraft type, anything higher then RED, is dangerous and prohibited.

"Higher then RED, you are dead!"

Exception is fuel "Fuel read RED, aircraft close to dead!"

 

TOT temp above red, you will loose an engine and/or engine fire

TOT overtemp during startup, you just toasted a million dollar turbine.

 

IN DCS: Mig-29 with PFM. TD with AOA higher then 15, scrapes burner cans, which causes engine fire.
