I'm an "OLD" A/P mechanic and wished I had this animation and clear explanation back in tech school, it would have saved me a lot of OJT time. Thanks and keep up the good work.
This video is excellent. I always find in lessons on propellors that the more context that can be given showing the mounting, plane of rotation and direction of travel, help to understand the concept being explained. At 4:30 in this video, if the image is rotated clockwise 90 degrees, the concept becomes much easier to understand.
That’s what I was looking for so much time. I was wondering why some pilots told me that the FTG on PT6 works only when the primary and secondary TG failed and that’s didn’t make sense for me due to so many info finding in websites, however none explanation (text) really help to understand like this video. I will keep waiting for more videos like this, thanks.
I have a few questions bro. Related to Pt6 engine props 1. What happend to the props if eng oil pres drop to 15 PSI ? 2. What action should be taken if props moves to reverse in flight ? 3. What is the max prop RPM before starting a prop overspeed governor check ?
What could be damaged (linkages) if reverse is selected when the propeller lever is not in the full fine (full forward position) while the engine is running? Great video by the way!
May want to check the theory behind aerodynamic twisting and centrifugal twisting. Happy to be educated but normally aerodynamic twisting goes to coarse and centrifugal twisting pitches to fine
Thank you for your thoughtful comment. It is true that these forces could move in either direction depending on how the manufacture places the pivot attachment and CG of the propeller. The easiest way to determine the direction of these forces is to examine how the counterweight is mounted. If the counterweight is mounted toward or built into the leading edge of the airfoil, its purpose is to move the CG forward. A forward CG will act to pull the propeller to course pitch. This is why many POH and maintenance manuals talk about the counterweights moving the propeller toward feather or course pitch. Alternatively, you could evaluate the mounting point of the propeller blade to the propeller hub. Typically, propeller blades are attached forward of the center point because the increasing camber allows more room to create a sufficiently secure attachment point. If this is the case, there will be more surface area aft of the pivot point and aerodynamic twisting will move the blade toward fine pitch. Ultimately, it is the responsibility of the PIC to know the details of their unique aircraft systems. The purpose of this presentation is to present general principles that can be applied to most systems but there will always be outliers.
Hellor sir, this is very big help for me becase im not good at english and having difficulties reading on MM. I hope you make another helpful vieos like this. Maybe you can make video for fuel system for pt6 engine also and oil system. Thank you so much
Thank you for your comments. I plan to produce a series of videos that cover all of the systems of various aircraft including the fuel and oil systems.
Thank you so much for this excellent video. Starting here my first job with a PT6 as aircraft mechanic.
You are welcome, congratulations on the new job!
This is the best Prop system explanation I have seen! 🎉 Exceptional!!
Thank you. I am glad it was helpful!

Thank you, I feel the same way. That is why I started doing this.
Very educational and nice graphics. This channel was quickly shortlisted as important.
Thank you!

Thank you for the idea. I will keep that in mind for future presentations.

You are very welcome. I am glad that it was helpful.
Best video on this I've seen.
Thank you
Adding the complexity layer by layer makes so much more sense than throwing a full system diagram up at once.
This is the kind of material i crave. Thank you for making this, an instant subscribe, save & like from me. 👍
Very good!
Making this informative video must have taken a lot of work and time.
Thank you!
You are welcome, I hope you have found it helpful.
Excellent explanation
thank you
Brilliant video and channel
Thank you very much!
Exceptional video.
Glad you enjoyed it!
My God! Such a cool video. Thanks!
Glad you liked it!
Brilliant Video
thank you

perfect explanation, thanx
thank you
the P T stands for Papyrus Typeface
nice
FCU video next please!
FCU is on the list, hopefully I should have it out in the next couple of months.

This is the best explanation.Could you create a movie how work FCU (Fuel Control Unit) PT6? Please.
Thank you, I am currently working on an FCU explanation. Watch for it in the coming months.
