@jasonkhood: That “barking dog” sound on an A320 isn’t the tail 🐕✈️ It’s the PTU balancing hydraulic pressure in the landing gear ⚙️ Makes that pulsing noise during system checks 🔊 The horizontal stabilizer moves quietly in the tail ✨ Next time you hear it, you’ll know what’s really going on 👀
For those who don't know, This is a PTU, otherwise known as a power transfer unit, during engine startup or shutdown, the hydraulic pressure in both engines may differ so the PTU will kick in to equalize the pressure (only on a320, left engine is green hydraulics and right is yellow)
