The original F-105D series has an error in the AOA tape.
The discrete reads "STALL", and is incorrect.
As you can see in this picture from the Flight Manual, it should read "FINAL"
As mine now does.
It is important to recognise that this triangle is not a stall warning, because if you believe it is, you will be flying incorrectly. The MIN SAFE SPD warning and the diagonal hatch above are the stall warnings.
The FINAL is the area that should be placed on the marker when you come in to land at the correct speed, altitude and fuel state in order to achieve a perfect landing. It is the FINAL APPROACH MARKER. If you think it's a STALL warning and try to avoid it, you'll come in badly.
It is also useful when taking off, as once you reach 130 Kts rotate speed, you can pull the nose up until the marker is in the "FINAL" triangle, and the aircraft smoothly lifts off at the correct speed.
