Weight, load and distribution experimentaion (Flightgear Cessna 172)

After the eventful flight

 I experimented with the Cessna 172 KOAK to KHAF empty, then load it up with passengers and cargo, and then back to KOAK. The flight to KHAF was fine, but at KHAF I think I loaded up too much passengers and cargo and on takeoff it was barely flying. Using autopilot when loaded is disastrous, as it flew fine.... until it turned into the wind, then all it wants to do is just stall the aircraft, and I spent something like nearly 2 minutes just hovering in the air at less than 60knots with the stall warning siren blaring mucking with the AP until I finally decided to just get rid of AP and flew it manually. And it didn't fly well with that weight until but I committed to get back to KOAK, taxi back to the apron and shut down and offload the cargo and (green faced) passengers. After that, just watching other flights for a while before I quit FG.

First serious flight I've been experimenting with weight, cargo and load. Now I really the kinds of effect it has on everything.

Going Supersonic CitationX

Supersonic! Mach 1

Simulation freezes when I open Route Manager. Resizing the window fixed it, but this happened.

Ghostplane!

Random images of recent flights around San Francisco in Flightgear

Just some screenshots of random flights past few days. I gotten the hang of the CitationX, but the Seneca seemingly trying to fight me all the time, especially during take off and landing. Interestingly, several times one of the engine didn't startup as expected, I have to choke it or something to get it to startup. So naturally I didn't notice that one failed to start the first time (right engine) and took off with a single engine, resulting in yawing, stalling and going into the drink. Subsequent flights I actually checked to see that both engines start up.

Didn't help there was some wind and turbulance on that day too.

My Flight Sim History, Part 1

When I was about 5 years old, bashing away at my father's Apple ][ , my father booted up a copy of Bruce Artwick's original flight simulator for me to have fun with. At that time, with the primitive graphics and wireframe outlines, I only recognized the runway and amused myself looking at the dials on the instruments watching them spin round and round. After a succesful take off in to oblivion (the map was only so large) and not knowing where the airport was I remembered typing in "A-I-R-P-O-R-T" to see if the computer got what I was trying to say. Of course, it didn't.. and that was it. I was having more fun with other games, namely, Hard Hat Mack, SeaFox, BreakOut and some sort of PacMan clone (I do not remember what it was called, but it sure wasn't PacMan), amongst plenty others.

Then we got a 286 computer. In 1990s, it came with Windows 3.0, which was state of the art. The 286 had been around for much earlier, but it was only after the price went down that we could get one. And there it was, among the dozens of games I got, was a diskette labeled "Flight Simulator 3.0".

That familiar startup screen - Runway 36, Meigs Field.

Flight Simulator 3.0. I actually (tried) learning VOR navigation with this one.

FS3 was what really got me hooked. The first FS, well yeah that was fun too, but it was the wrong time, I was about 5, it was on an Apple ][, and it's more like a novelty. FS3 was light years ahead in comparison. It had 640x480 graphics, it had nice vector graphics, it had color, it had buildings, and it had a whole world of airports to explore (north America). I also had manual for FS3, which I read it over and over the pages became so worn. I treasured that manual; I still have it today.

I cannot recall how many hours I put into FS3, even choosing it over other games of the time because my fascination with flight and planes are so strong. Eventually I figured out that there are other places besides Chicago Meigs Field, and make use of the airports list to explore places. I practiced takeoffs and landings, I show it off to many of my poor friends, whom, many of them was disinterested with my toying around with a computer plane that doesn't shoot missiles and things. I did get convert a few friends who eventually became simheads. At that time my passion for planes are going overdrive too, everything is airplane themed about my life, including a shirt and cap that my mother bought and sowed on various badges telling me that it was a pilot uniform. Although it had a shuttle on it. And I loved it.


Back to the FS3. The sim had one annoying feature in that the planes flew totally unrealistically because of the simplistic flight dynamics. It flew on rails, basically. And the plane will continuously move forwards in flight, no matter what you try to do, even in a stall. It will move slowly, but it will be forwards. The very basic flight dynamics also meant that you will go upwards if you point the nose up, and down if you point the nose down, but not nose up downwards and not nose down upwards, which makes landings totally unrealistic, because with every landing, you slam the nose wheel into the ground. I couldn't figure out how to make planes land like the real-world planes, and bugged my poor father to no end wondering out loud about the problem, which he had no real solution for. This and a box of an older FS2 I found at a computer shop compounded the problem because it had a screenshot of a Cessna in flight at the end of the runway, in a nose up altitude, as if flaring for touch down (it was a box marketing trick, you see, and poor 7 year old me thought that FS2 had that feature.)

"Random failures"

 This morning I had some time, so I started up FlightGear and took off from WBGR and practiced touch-go a little bit with the Citation X. Once in the air about 6000 feet, I was browsing the menus and saw "Random failures".

 Feeling adventurous, I selected it. A menu popped up, asking for failure sequences and time to fail. I selected within 1 minute and some other option I did not bother to look through.

 Must be something I did, because the failures came piling on one after another!! First the electrical system, so all the instrumentation blanked out, including the Master Caution lights. I began turning the aircraft around, did my imaginary emergency calls, and prepare for an emergency landing. As I did so yet another message appeared telling me something failed.

And another.

And yet another.

 I simply did not have time to understand the failures! At one point I saw the message "Engine 3" fail, and thought, huh, CitationX only has two engines... but didn't think much about it - I was on single engined approach.

 Things kept failing. I couldn't even keep track of what, exactly. As I was appraching to fast, I hit the speedbrakes to slow down, and as I was slow enough I retracted it - and guess what? Speedbrake fail! So I increased engine thrust and pulled up - this was when I was about 1500ft agl, and just in front of the runway.

 On FlightGear at WBGR, there is a big tree at the end of the runway. I clipped that tree with my wingtips when I watched the replay later.

 The plane was not properly lined up, and I did some aileron turns to line up, and THAT failed. Fortunately, the last turn was lined up relatively well and I had to use rudder alone to align. Hit the runway - hard- at an angle, wit ha high sinkrate, at just stalling speed (less than 120kts) and probably slapped the wingtip there, used rudder to further align with the runway and hit the brakes.

 Screeched to a halt. Well the CitationX in FG had suspiciously good braking distances but I''ll ignore that for now, that would be a good thing in this situation.

And then, Engine 1 failed. The plane is now dead in the middle of the runway with no power.

Didn't stop there though, things kept failing. Things that I didn't know existed on a plane failed.

Oh, what fun! But I'm probably not going to try Random Failures again.... with the kind of failure I just had, it was probably an onboard fire by the looks of how everything just stopped working completely.



And someone needs to cut down that tree growing in the middle of the landing path...

Pictures soon..

Citation X WBGR > WBGB

I forgot to take screenshots. Here's a beauty shot of a Citation X from FlightGear wiki site.

What's up, internet!

 I have been neglecting this blog lately and for a good reason, I haven't touched FlightGear in a while. Busy with Kerbal Space Program... oh my that was so fun.

 So I learnt yesterday that FlightGear 3 was out and of course I downloaded it immediately.

 First flight I did was with the Citation X, taking off in the early morning (sim time) from WBGR (Miri) and, due to time restraint (it was night and getting late, real time) flew a short distance and landed at WBGB.

 I thought I did pretty well, landing was smooth although I did have to make a few steep turns and the roll & sink rate warning sounded a bit (oops), and did have to make use of the spoilers while in mid-air to slow the plane.

 Random thoughts : The FG3 is far smoother than FG2. And either my skills have improved, or it seems easier to land a Citation X (or it has to do with the smoother simulation).

 Terrain data for WBGR and WBGB is basic. I wished I could make the terrain and contribute scenery data here but I have tried and simply stumped by just how to go about it. Plus, I hardly have time nowadays, but I will figure it out one day.
