737NG Simulator Project

UPDATE: added video 6dof MP 1st Motor Gearbox Test (5/27/2014)

By Mike Sherick


This letter is in response to Ian's reply to me, but I thought it best to copy you Thanos, as I wanted to communicate the same information to you as well.  I truly thank you both for your emails and objective comments.  

I fully understand that it is difficult for to comment specifically on the "general information" that I provided.  This is especially challenging since I am not a mechanical engineer and I do not have formal knowledge concerning the proper use of engineering terms to describe things - something I mentioned to you on the phone when we talked.  You have been kind to reply, and I respect the general nature of your comments, considering the limited set and somewhat disjointed of information I have provided.

Given that the nature of tying to build a full-scale 737 Sim Motion Platform is in and of itself a huge project, I am sure that most folks would pass this kind of project by, and rather spend their time playing golf or reading a good book.  All that is fine, but that has never been my personal mode of dealing with interesting challenges - like building  full-motion platform, or building my full-scale 737 Sim, which is now flying nicely.  Many of the projects I have done over the years have all turned out to be good learning experiences, and quite rewarding.  I expect that the 6dof Motion Platform falls into this category.

Sending Positive Energy Your Way, Zaharie! cont'd

I'm still sad and shocked hearing all these negative and false information about Captain Zaharie, in a degree, that I don't watch the news anymore. 

I believe a terrorist wouldn't be quite as open as Captain Zaharie with his love and passion for flight simulations. Many commercial airline pilots from all over the world contact me for help in adding motion to their home made simulators that share the same interest as Captain Zaharie. I don't see that as a "threat", I see that as "for the love of flying." Let me point out one thing, race car drivers have motion simulators in their homes as well. Will they be deemed terrorists too? 

I heard these past days about "logs" that were deleted... I'm sorry,  how do they know that were deleted deliberately and not just because they are just "temporary" logs? The flight simulation software have many  plugins that distribute data from the flight simulator "game" to all plugins that handle the virtual cockpit instruments, and guess what, all these are holding logs merely for performance feedback. As far as I remember unless I "save" a particular flight, the data for the session are lost as soon as I close the flight software.

Flight simulation is fun! One does not have to worry about the stresses of actually flying a plane with all the safety concerns, limitations and consequences that go along with commercial flights. FAA rules are very strict. It is also a very good tool to learn to fly an aircraft or virtually visit destinations anywhere in the world. However, it is completely different to actually get behind a yoke of an actual plane. 

Adding motion to the simulator provides the pilot with realistic feedback about the planes reactions and makes the experience more immersive, this is called "motion cues". For a 6DOF steward platform like the one Capt Zaharie was building, a complicate math model is required that uses classic filters, to recreate the motion and the reactions of the real life vehicle or plane. The motion platform itself is nothing more than some robotic intelligent parallel actuators. There is nothing more to it.

I'm really a busy man and don't have much time to talk about it anymore. I'd like to thank all the news reporters for their inquiries but I really have nothing new to add. I do not wish to be an object of "something to talk about" just to "cover" the advertising time.

Sending Positive Energy Your Way, Zaharie!

Where ever you are, I'm hoping you are safe!

Many pilots contact me interested in making "home" simulators. Zaharie along with some others pilots actually used my motion controllers to upgrade the realism of their simulators by building motion platforms.
I feel saddened when I hear the news media with their "theories" of suicide and terrorism of Malaysia Flight 370 at the hands of Zaharie.

I have known him for over a year now and found him to be a good man, husband and father. He was proud of his expertise of do-it-yourself constructions, he even shared with me and a colleague (the now infamous YouTube video) that is being splashed all over the news about his energy efficient air-conditioner.

I'm sick and tired of the negativity the media is spreading about this man without any proof; just theories!

Thinking of you buddy!
