Circular Runways?

I think circular TAXIWAYS made more sense. Thevideo shows just how easy it is to make a wing/engine strike. And in turbulent/windy/freaky conditions, the pilot would have to constantly adjust during the banking turn. I have a hard time in a simulator on a straight runway (and apparently some pilots do too in real life).. what more one that requires you to make a banking turn..

...and just how do you do a crosswind at the moment of touch down? Just imagine a sudden crosswind during touch down and the rudder turn right after that would have to be huuuge to compensate for the xwind + runway bank + runway radius...

Prepare for Impact!



"This 3D game has been developed in the context of an international, aviation safety research project (http://hcilab.uniud.it/aviation), aimed at exploring possible new approaches to safety education. The game reproduces the experience of real-world aircraft emergencies from the passenger’s viewpoint, with the highest fidelity allowed by today’s mobile devices.

In each virtual emergency experience, the player can try first-hand right and wrong actions that a passenger can take, and see the positive or negative consequences those actions have. Your goal is to take all the right decisions to come out from the plane unharmed as fast as possible.

The game also offers the option of publishing your best evacuation results on world leaderboards. The different levels of "Prepare for Impact" depict major types of emergencies, such as in-flight decompression, ground collision, runway overrun, water landing, and crash landing.

Moreover, they are able to simulate the different threats that can make aircraft evacuation more complex, such as fire, smoke in the cabin, water, unusable exits, and others. "


I chanced upon this. Doesn't help my flying anxieties at all, but I guess there is some 'edutainment' in safety briefing and escape simulations out of tight spots and also prepares for the 'drop everything and get out in the safest manner as possible" in the form of a timed score.

What do you all think?

The Story Behind Flightgear Default Airport, KSFO (And also MSFS & X-Plane)


So while having some time to myself and flying around KSFO (San Francisco International Airport) region I thought to myself; is there any significance to using KSFO as a default airport for Flightgear?

Although there is not any official reason as to why KSFO was chosen as its default, here's what I got when I asked & searched around:There are probably some requirements for an auto-startup airport to make a good impression to newbies in flight sims, which is having good scenery of built-up airports, city objects, great landscape features.



KSFO, or San Francisco International Airport in San Francisco, easily meets just such requirements. Surrounded by hills on one side, and a water feature (bay) on the opposite end, and some buildings and bridges. So no matter which part on the runway you spawn, you will see some features and details as visual eye candy. KSFO also offers some fairly advanced challenges for relatively new users, such as having terrain & structures to avoid during take off or landing, but still has the open water landing approach perfect for people attempting their first landing.

A short flight into the skies and a few turns in the correct direction and the world famous Golden Gate bridge will greet the new user, piquing his or her interest to go closer for a look, and there's also the famous Alcatraz island and various other landscapes / structures to buzz around and experiment with flying.





And once the user gets the hang of it, start flying to the other plentiful nearby airports around it, like KHAF (Half Moon Bay) or KOAK (Oakland International) both of which are just a really short hop from KSFO.




So, KSFO as single auto start place is a very good choice, for the first time users to experiment, and the place is literally full of other airports and airstrips to go to all within a short time.


What about MSFS's Meigs Field?


I don't know if you're old enough to remember the first few versions Flight Simulator, or even the Meigs Field, but the original MSFS's startup airport uses Meigs as its default starting airport. 

Although there wasn't an official reason ever provided by Bruce Artwick, the creator of the original Flight Simulators in the late 70s & early 80s, people surmised that Meigs was chosen partly because Bruce was from Chicago, and also Meigs is a very beautiful airport jutting out into the lake surrounded by a marina with boats, yatches (although none of those are depicted in the original simulators) and world famous buildings.

In fact it was probably a no brainer choice as the default back then, as upon startup on Runway 36, the first recognizable thing you will see after take off is Sears Tower and the John Hancock Center, and with nearby Chicago O'Hare International Airport & Midway International Airports to fly to.




It was a beautiful airport, but alas it didn't last. In 2003, the through a combination of some political madness, some post 9-11 panic and other reasons unfathomable to me, the Mayor of Chicago destroyed the airport by bulldozing the runway with large X's on it, even stranding some planes that are still parked the airfield.







What about X-Plane 10's Seattle-Tacoma International - KSEA?


 Well I can't find any info on why KSEA was chosen as the default start up airport in X-Plane, but it was a nicely detailed, nicely modeled airport, with an odd runway that slopes upwards so your horizon is shortened quite a bit. The scenery in X-Plane is also odd in that it comes with "built-up" data generated at random based on how the roads are and how likely a buildings are placed.

 Because I only had the X-Plane demo for a while, I don't know too much about X-Plane other than I love the demo, it has great visuals especially the lighting.

 X-Plane apparently also changes their default every version. In version 9, it is at LOWI - Innsbruck, Austria. In version 8 it was at 
KSBD - San Bernardino, California, USA.

Worst Places to be a Pilot



 I just saw this on youtube, and I'm hooked..


Slight note : The way some of these pilots are treated (essentially living in luxury in one of the vids), I'm not sure if that title holds up well....... but of course it's most dangerous places to be flying that's for sure..

Air Traffic Flying Around Storms Near a Busy Airport




What happens when thunderstorms hit the world's busiest airports, how the planes fly around storms and go into holding patterns can be seen clearly.

Boeing's 787-9 Dreamliner & Airbus 350 Performance at Farnborough

Boeing's "Rehearsal" video That climb was 45 degrees, holding it for about 5 seconds and then a negative-G back to level. That, for an airliner is very impressive. And the 60 degree bank! For most airliners 60 degrees would most definitely upset the turn. Another maneuver is the touch n' go with a banking climb, which was eventually banned! Airbus 350 doing the "combat climb". The steep climbout is way shorter, and it turned to its right. No negative-Gs.

The Walker

 The Walker is sort of an add-on for FlightGear that allows a "person" to get in and out of the aircraft and walk about. Hence the "Walker" name. The latest version of Walker has some options, mainly to add accessories such as a flight helmet and shades, or change gender or theme (mechanic, pilot, flightsuit etc.).

Standing on the runway of KSFO watching a B777 takeoff, and fly around like a fighter jet.
  To install the Walker, download it from here and simply unzip the Archive to your fgdata/Aircraft/Generic Folder.

  To add the Walker to your Aircraft (you must do this),  replace the Entry at the top of your -set file with this line:

< propertylist include="Aircraft/Human/Include/walker-include.xml" >

The Keys "a", "A" and "s" have their normal Binding when not in Walk View or Walker Orbit View.


Walker Movement
The Walker gets out by clicking on the "Walker" Menu option "Get Walker out".
The direction of movement is controlled with the mouse. He runs forward with the "w" key , backwards with the "s" key. Lateral movement is carried out with the "a" key to the left and the "d " button to the right. Run with "A" .
In the Walker Menu you can change Gender and Outfit, and create custom Animations and Poses.

 When I edited it into the C172p, pressing "s" just turns the engine once. As in, it goes "hek" and then stops dead instead of "hekhekhekhekhek". But if I toggle the Walker outside, then pressing s does start the engine, and you get the hilarious view of the plane starting up and then running away from you.

Apparently this is an issue with the C172P only, other planes did not have this problem. The only way to start the plane is to toggle the Walker outside, ie. start from the outside of the plane, like one of those biplanes. Be sure parking brakes are on!!
