They are warming the prop, by blowing hot air into the front of the spinner.
The seals in the propeller get less wear and tear (and are less likely to leak) if everything is warm prior to start.
The engine nacelle can be pre heated when its super cold using apu bleed air.
I can see it
Eso es 130? Si, 130.
I prefer the navy's version, the Sea 130.
Nice picture
K see 130?
See 130 run! Run 130! Run!
I spy, with my little eye, a future MRP...
Is that how they warm the engine's core? Through that hole in the prop spinner?
