FS thunderstorms

Hey all,
I was in the midst of an epic flight to the Caribbean, flying from Jonesboro Arkansas to Tampa Florida. I was using real weather so I came across some inclement weather--thunderstorms to be exact. I saw the lightning, heard the thunder and my plane was being tossed all over the place at nearly 200 knots. I'm pretty sure I had done what is called 'flying into IMC' which is frowned upon in real life due to the potential for loss of life. I ended up getting out of there and made a beeline for the nearest airport (Sikes Airport in Luverne Alabama), greased the landing and parked my plane to wait out the storm.
Now I know in real life this would have been the most prudent course of action, but has anyone ever crashed in FS2004 by flying into a thunderstorm? Has anyone been hit by virtual lightning, and if so what happens?

I've been bounced around pretty severely on landings during a t-storm in FS.
 
I dont think lightning has any affect on the aircraft in FS9, it's just a visual effect. However the turbulence is potentially damaging. I've lost a light GA aircraft once in FS on approach during a thunderstorm - the turb overstressed the airframe despite my comparitively low speed.
 
As others have said the lightning and thunder are just effects but the turbulence associated with the storms can damage/destroy your aircraft if you have 'stress causes damage' enabled. I had an aircraft break up around me during the practice sessions for the Round the World Race but thankfully it was only a practice session and I was flying as a 'wingman' and not the 'baton holder' so no damage done, apart from to my pride.
 
I once flew a plane into a mountain because I was so busy watching the lightning checking out the results of a freeware lightning enhancement package....Massive Storms on Simviation.com. Have also boogered up some landings due to strong winds and once had my Tigermoth flipped over by strong wings as I was taxiing for take off...not a good idea to try to fly a Tigermoth during 60 mph winds.

heh, reminds me of a real life auto incident a friend was involved in a while ago. He was driving his brand new car down the road and admiring the view outside the Uni campus on a hot, hot summers day. His appreciating a particularly scantly clad student was rudely interrupted when he hit a parked car...

On the FS side tho, as models get more realistic and more complex, another real life issue is emerging - pilot workload. It really does pay to read the manuals thoroughly on many new models. I recall a flight in Eaglesoft's Cirrus a while ago. Having skimmed the manual I figured I'd er, wing it... Of course, this meant spending a lot of time head down trying to figure out the avionics, esp nav which had me sufficiently confused so as to drift a long way off course. Then the Rwx closed in depriving me of VFR nav, then the fuel warning came on due to inadequate preflight. So there I am trying to descend below cloud, low on fuel, lost and still trying to get the nav to assist when ker-splash... DOH!!

I have been hit by lightning several times in FS, doesnt do anything but a white out on the screen for a second. The turbulance on the other hand can be a hand full. Some planes seem to handle this better than others. Best to go around the storms.
 
Funny thing about that storm...
Yesterday when at work (I work in customer service for a cable company) I talked with a guy from the area; he mentioned the storms in the area; at that point I mentioned I was familiar with that storm and related my flight simulator experience: flying into the storm, getting tossed around and making a beeline to the nearest airport to wait out the storm. He didn't hear the 'flight simulator' part and told me he was glad I made it back in one piece. I didn't correct him; he was an older guy and didn't want to confuse him any more than I had.:isadizzy:
 
Hey all,

Ummm.. first of all, haven't there been numerous early season tornadoes down there???? I'd think a prefight wx briefing might be in order...

There are several considerations here. The stresses on an aircraft in flight vary with the conditions and turbulent air is a significant one.
VA Design maneuvering speed, also known as the "Speed for maximum control deflection." This is the speed above which it is unwise to make full application of any single flight control (or "pull to the stops") as it may generate a force greater than the aircraft's structural limitations. The heavier an aircraft is loaded the faster this speed.
In turbulence it is easy to make large control deflections in an attempt to 'fight the aircraft' and if above VA you risk an overstress which can be destructive. If you must get into the rough stuff, slowing down is important (just as slowing down on a rough road). Often VA is shown as the top of the green arc on the ASI, but not always.. it should be found in the notes or operator's manual (oops.. sorry for the bad language)

I'm pretty sure I had done what is called 'flying into IMC' which is frowned upon in real life due to the potential for loss of life.
Flight into IMC isn't bad - it happens every few minutes as IMC is Instrument Meteorological Conditions - anything from <3sm vis to rain, cloud, fog, etc. It's not the IMC but what type that makes it an issue and you don't even have to fly "into" it in some cases --- yours is one of those.

Weather radar was required in the 50's so large commercial transport aircraft crews could see "through" thunderstorms and if the radar was inop. a flight was required to remain visually clear of the storms. May 12, 1959.. a Capital Airlines Viscount crashed while maneuvering around a cell... The aircraft probably reached an airspeed of 335 knots, which is 15 percent in excess of the Viscount never-exceed speed or about 5 percent in excess of VD, the maximum speed demonstrated in certification. At an altitude of approx. 5000 feet both horizontal stabilizers simultaneously failed downward separated. Following separation of the right and left stabilizers the aircraft pitched down violently so that all, four engine nacelles broke upward from combined inertia and gyroscopic loads. Immediately thereafter both wings were subjected to extreme downloads under which the right separated and the structural integrity of the left wing was destroyed. With the nacelles, right wing, and stabilizers gone, drag induced by the left wing yawed the fuselage violently to the left. Forces to the left tore off the vertical fin with portions of the fuselage attached, the latter already weakened when the left stabilizer stub tore away. During the subsequent gyrations the left wing broke up, its fuel cells were opened and the flash fire occurred. At the same time the remaining fuselage disintegrated. (metallurgical analysis showed the entire break-up sequence up to the loss of the tail fin took 1.5 seconds.) http://aviation-safety.net/database/record.php?id=19590512-1

Yes, you can overstress an FS9 a/c the same way. I had an 'almost' in the RTWR a couple of years ago online, in front of 4 or 5 witnesses - a night approach into a black pit in Siberia, a few clouds as I approached, but as I turned final it turned into a thunderstorm. I saw a flash, some movement and next thing I was -- I dunno.. Probably 15 degrees from total inverted flight with the nose down (altimeter was unwinding awfully fast). I pulled through, saw a windscreen full of trees against black and managed to recover on instruments at about 200 ft... took 5 to clean the cockpit, re-orient myself and land (anticipating the turbulence this time). FS9 measures, handles turbulence in 'levels' - I've seen Lvl 4, been unable to use autopilot in Lvl 2 and don't want to find out if there is a Level 5.

I ended up getting out of there and made a beeline for the nearest airport (Sikes Airport in Luverne Alabama), greased the landing and parked my plane to wait out the storm. Now I know in real life this would have been the most prudent course of action, but has anyone ever crashed in FS2004 by flying into a thunderstorm? Has anyone been hit by virtual lightning, and if so what happens?
Actually the most prudent course would have been to tie the plane down at Jonesboro and go have a beer.. come back tomorrow, but...

Lightning in FS is benign except for the vision issue.. and mostly so in r/l. I watched a B737 get hit on short (50ft agl) final and it had no apparent effect - until, after landing, they discovered the 1" dia. hole in the fuselage right below the First Officer's seat. A/c was ferried out the next day to get the pressure hull repaired. Ferry flight was thru the mountains at 10,000 ft asl much to the delight of the crew.

Using ASA to get real world weather including the up and downdrafts that come with any good TS I have had a few exciting rides in FS that were a nice reminder why in real flying I would never go anywhere near one of those things in my Saratoga.

As it was I was flying Milton's Howard 500 and despite being relatively light....but not too light either the big twin could barely deal with the winds around the storm. I had wrongly figured a 30nm diversion would be enough to stay out of the worst.

You can experience 100+ mph winds hitting the airplane from all quadrants. And almost at the same time. Somewhere I think in the aftermath of Scott Crossfields fatal accident there was a site that showed the wind shear in that particular storm was in excess of 160 mph. So one minute your airplane might be forced up by 80-100mph updrafts and the next it's forced down by an 80-100mph downdraft.
That is easily enough to over stress even the strongest airplane.

But even if you don't get into the wind shear region....your airplane might simply not have the power to out climb a prolonged downdraft just to maintain altitude. And even as you try to turn and get out of what you just flew into things might change on you again.

The flight in the Howard was so "real" that once I got everything sorted and headed to a safe destination to wait things out I noticed I had sweaty palms and an increased pulse rate.

Like SirGalahad mentioned IMC is not the problem....that is what an IFR rating is for....but IFR does not mean I can now fly anytime and in any weather. Unfortunately some people do not understand that distinction and blast off in their SR22 into Wx where even the airline captain decides to hold off for a bit.

I've never tried to fly through a thunderstorm. The winds at the perimeter of storms are enough to make me either go above, around, or change my destination. Flying through clouds and turbulence is bad enough.
