Uncontrolable aircraft in thunderstorms

[stans 704]

As flippant as NZ255's answer may seem, he is correct.  It is ill-advised to penetrate or fly beneath a thunderstorm as the winds are unpredictable.

I guess I must be missing something but what does the headwind value have to do with anything? Seems kind of irrelevant.

What was your indicated airspeed before it jumped to 300 knots?

It is easy for the KIAS to increase rapidly approaching TS caused by the outflow boundary.  I've had it happen in my RW flying when maneuvering to land in the vicinity of TS.

I agree overall Dan but anomalies excepted, the general turbulence scale is pretty close. My comment is more toward those who feel that 20-30% is more accurate. I don't believe that figure is even close on a general basis.

Perhaps I tend towards the 20-30% settings because the wx engine treats every cumulonimbus the same, they all seem to paint deep red and they all seem to be the same size. I rarely see ASP4 paint rain showers as showers, they always end up as the worst nature has to offer.  I've never seen this from the cockpit, for example most convective formations that top out below FL200 are usually benign and will paint deep greens at most, whereas the wx engine seems to take every convection event at its worst.  The improvements in the wx engine over the past decade has been significant, and I look forward to improvement in this specific area.

I totally agree Dan! Compared to what it was, it's exceptional but compared to what it should be - that needs some work.

Hi All

 

In relation to Downscc's question,, no I am not running any EZDOC programs. All I run is navigraph moving map charts, PRO-ATC/X active sky and prepar3d v4

Yes guys I realise you are not supposed to fly through thunderstorms. I am more intrigued about my aircraft data and response. When you are at 2000 ft with a headwind of 9 knots, with flaps 1

then within seconds you are doing over 300 knots with no inrcrease in wind data, or no increase in altitude , You have to admit its rather strange?

Maybe in the next active sky release?
