Acceleration.

[Grundar]

This has become an unexpectedly interesting discussion. I stumbled on a conversation concerning Australian Mirage IIIs and from what I gather they had a stability assist system of some sort and on landing approach they had to switch a pitch assist mode off otherwise it will try and keep the nose pitched up on the approach AOA on touchdown, much like the M2000 FBW does in DCS. Would this be for the same reasons?

 

Just a little disclaimer: This was a while ago and I might be mistaken with how I heard and remembered it. Plus also it's concerning two very different aircraft, so there's that. Just wondering if they had common reasoning.

 

Re Mirage III's in RAAF service from pilot interviews in the book "The RAAF Mirage Story"

 

 

"Back in the circuit for landing, the delta wing made the Mirage handling akin to that of a laden gravel truck. The aeroplane clearly loathed anything below 300KTS. Plenty of back-stick was required to keep the nose up such that the hydraulic pumps working the flight control surfaces, combined with the buffeting from the high angle of attack produced a noticeable "groaning" throughout the airframe. Landing was generally a matter of getting the aircraft on the ground with reasonable haste as the high ground speed (160KTS IAS) consumed the the remaining runway at a great rate."

 

I can't really find anything in that book on stability control, but I imagine that they would of wanted to deactivate it once the got those back wheels screeching on the ground to bring that nose down and start bringing the speed down quick.

Mirage III was astonishing plane for its time.

But Mirage III flying tips are irrelevant to Mirage 2000. :smilewink:
