Bumpy Real Weather

I notices that somebody was having problems flying the York also, another comment was made about possible Real Weather being the cause.

Monday evening approx 2200 hours I did a circuit of Stansted in the Viscount 700 with FS9 Real weather (updated every 15 mins) and found the plane generally unstable at all altitudes upto about 6,000 feet (my ceiling) - especially on the approach with the ASI fluctuating by 20 knots or more. I realise the real weather systems over the UK are somewhat windy/unstable presently and wondered if the weather element of the program was having difficulty in interpreting the 'subleties' of same?

I normally use Active Sky 4.5 but as said above, for expediency on this occasion just used the FS9 Weather.

Hi Crisso..

I do think that 'real weather' tends to amplify aircraft movement some times.. the effects of which vary depending on what it is you're flying. I used to be a big fan of AS4.5 and still have it installed on this pc but a quick try the other day found it unusable for some odd reason. To say it caused stutters is an understatement in the extreme!! :shock:

The York in particular seems sensitive to weight but as everything else you tried seemed 'flighty'.. it's probable the wx was to blame :wink:

Hi Crisso

I always have real weather and have no problem with the York

Even taking off in a crosswind the other days it remained stable and in fact one of the easier to control

David, you need to update to ActiveSky 6, the current version. Much smoother.

Some interesting comments sofar guys. Just to re-iterate, my input was regarding interpretation of the actual weather by the appropriate programs (i.e. FS9 Real weather or Active Sky 4.5) and not about any particular aircrafts behaviour. (Incidentally, the York will be installed on my computer imminently!) I may have to consider the suggestion of updating to Activesky 6. Frankly, as those based in the UK will testify, our actual weather is pretty wet/windy/squally presently with fluctuating temperatures.

Tks CT :smile:

I do have AS6.5 but I think it's a little too much for this old dog of a system. I started getting an error with the 748 and the report FS was giving indicated an AS module. It's likely I have removed something which, while seeming to fix the 748 issue has caused one within AS itself. Best thing is to remove it totally and install again though I may try 6.5 on here again :wink:

Not really about weather. But Dave's note on the York and weight sensitivity.

I never tested behaviour with weight added or removed from FS9s Fuel/Load tab. But agree that her trim does change more than I would have liked as fuel is burned off.

The PNs for York do state that she becomes increasingly tail heavy as speed rises. So much so that in a dive Pilots are advised to trim into the dive to prevent an excessively rapid recovery stressing the airframe.

It was me that made the comment about ASv6.5 weather the other night - and I was flying the York at close to gross - Paule is spot on if you look at the fuel feed for the York everything feeds to the center tank which is way forward of CG so obviously as you burn down the CG will move aft. Not a ig problem so long as you remember to trim forward all the time on long flights - It also helps if you when you load the aircraft any real weight on the freighter version (ie the virtual Proteus) goes as far foward as possible then you wont have half the trim problems - Ive been waiting for folks to post over at CBFiles before I begin the "how to fly.." thread but so far no one has posted (specifically the gent who made the comment about it being unstable)
The reason We (at CBFiles) have been so quick to jump on this is personally I feel that if you want to make adverse comments or criticisms thats fine BUT Not in the comments box of the download , but in a forum where it can be discussed and corrected - ALL that comment tended to do was to turn people away from a perfectly serviceable model - If Mr Melton comes here and reads this forum I wich he would reply because having made his rather nonsensical comment he has now vanished

Ill get orf my soapbox now

I think you may have mis-interpreted both my original and possibly subsequent message on this thread.
I would respectfully ask you to re-read same since, I was simply only asking for other peoples recent experiences/comments about how they felt the various 'Real Weather' programs had recently affected their flying in various aircraft - not any particular one.
As said previously, this subject is of particular interest at present since, here in the UK we have had very unsettled/changeable weather of late and my question was, are the Weather programs maybe having trouble in deciphering the actual metars?

p.s. I am hoping to install and fly the Avro York imminently and have noted your comments on trimming, etc.

Hi Crisso..

I don't know if it's just me but I find the DC3 seems to carry it's own wx with it.. even if I have none selected :shock: Any flight of an hour or more duration will have it bucking around at some point then a minute later.. all is calm again :think:

They've forecast high winds and plenty of wet wx here again over the next couple of days so batten down if you plan to fly in UK airspace soon :lol: That said.. the current conditions are ideal for any forecaster.. sunny periods with outbreaks of rain! :lol:
