Re: Are all EASA part 66 licences considered equal?

Yes, an EASA license is valid in all EASA member states. Now whether of not airlines are going to subject you to the same fair treatment is a different case, because certain southern European states have a reputation for turning out poor pilots, and I know for certain that pilots from one or two co...

Are all EASA part 66 licences considered equal?

Is the licence given by any of the EASA member states considered equal and accepted by others?
Or some authorities/recruiters don't accept licence given by some particular authorities?

I am asking this question as I am planning to apply for Greek basic licence.

Do Airlines/MROs responser type rating course for you?

Hello,

How is the job market for certified maintenance personnel in Europe?

I have 10 years of maintenance experience on A320 and have the EASA basic license.
Do I need to finance my own type rated course or do Airlines/MROs who will employ me sponsor the course for me?

RE: Why Do Turbine Blades Have Firtree Roots?

After much searching on Google in addition to the above explanation I found this. Fir tree root gives it a large bearing area to take up the heavy stresses, and this bearing area is nearer to the axis of the blade. Resulting in resistance to cracking at the root as compared to the root in which the ...

Why Do Turbine Blades Have Firtree Roots?

Generally in almost all engines the compressor blades have dovetail roots and the turbine blades have the fir-tree roots.

RE: Flat Rated Temp

Found this explanation which gives flat rating as a function of turbine exhaust temp, I think which is more logical.

Gyroscopic Effect Of Turbo Fan Engines

Hi there!

the gyroscopic effect due to the rotating mass affects engines, it is more pronounced in turbo prop engines due to a larger fan.

Even though it is less in turbofan engines is there anything done to counteract it in modern turbofan engines?
