Hey Guys, So now I have encountered yet another problem! This time, my flight will be going normal and all of a sudden, without warning, the aircraft simply stalls. The weather is fine and this occurs sometimes while climbing and at others when I'm at cruise level.Thanks!

What type aircraft?Do you have fuel?Are the engines still operating?What are the winds aloft?

It is a 737, with plenty of fuel, fully operational engines, and good weather with partly cloudy skies but no real wind issue (I assume that is what you mean by "What are the winds aloft".

....all of a sudden, without warning, the aircraft simply stalls. .... and this occurs sometimes while climbing and at others when I'm at cruise level.

what 737? developed by?climb speeds at what altitude levels?cruise at what alitude and what mach speed?

.The weather is fine

real world weather? if 'real world' what weather program? default FS or addon weather engine?are you using a FS weather theme?--

Wow sorry about the 5 month delayed response, I guess I didn't get your message. This problem appears to have vanished; I think I may have to do with pitot or because I mistakenly kept the autothrottle dangerously close to stall speed, went through turbulence and stalled... Do you know what the spedometer (wrong term) on aircraft read units in? Is it knots?

To address your matters (by the way, I only fly the B744):a. if you haven't switched on the pitot head heat by the time you enter freezing temps., then at the most, your Air Speed Indicators (ie. the one in your MFD and the standby instrument) will not give an accurate reading or no reading at all). This shouldn't cause a stall.b. it sounds like you entered turbulence or a sudden wind shift (especially if you are flying at 8x or 16x sim rate on autopilot). This can throw the aircraft around violently and a stall can result, unless you're quick enough to disengage the sim rate and autopilot. I never fly on autothrottle when using 16x sim rate, for that reason. I find that in sudden wind changes, the aircraft is better balanced with the throttle set manually at cruise. Sure speed may increase or decrease (depending on the aircraft's attitude), but it generally won't stall and you have time to recover if need be.c. The Air Speed Indicator in your MFD (Multi Function Display) reads in knots. You will need to check though, whether you have set it to read as TAS (True Air Speed) or IAS (Indicated Air Speed). IAS is the realistic one that is used on aircraft. You will need to Google (!) the two to learn more about them, as there is a lot of technical info as to how the two vary and what determines the speeds they show.Chris David
