Isn’t the phenom susceptible to being uncontrollable if it loses GPS or Ahars or something? There was an incident I think in CA of a Phenom losing control recently.

That doesn't affect your actual flight controls just your instrumentation.

It affects your flight controls at altitude. The airplane violently Dutch rolls if you lose the yaw damper. NetJets had a couple of events like that. The GPS and AHRS are tied together so if there is a complete loss of GPS signal you lose AHRS which kicks off the autopilot and you lose the yaw damper. Only at like 24,000 feet do you start regaining control.

Why is it called a "Dutch" roll? Why not "French" roll? That seems to make more sense to me. Things that make you go hmmmmmm....

You should be able to engage or disengage the yaw damper irrespective of the autopilot, no? Or at least be able to reengage it if the autopilot fails. Can't imagine the airplane being certifiable any other way.

The airplane has only one yaw damper, they added a ventral rudder as a backup but it is not effective at high altitudes.

The yaw damper is tied into the autopilot.

Airplane was certified under Part 23 instead of Part 25.

That’s old news bud.

They were never violent. They were unsettling until the source issue was found.

.70M and 30k, everything smoothed out.

New avionics upgrades have eliminated the Phenom-enon.


Tsk tsk... more mud slinging.

Don't get butthurt, there is no mud slinging. It is old news for you because you work there, somebody that doesn't work for NetJets asked. This latest issue as well as the one I mentioned, both aircraft was reported as UNCONTROLLABLE. Pilots in the sim during the dutch roll demonstration have thrown up and shut the sim down and as somebody who flies aerobatics, I can attest that the dutch roll demonstration in the sim is absolutely severe.

You know that somebody can talk honestly about something without you taking it personal, right?

The first aircraft to experience this:

Exactly.

You don’t work here any longer and the longer period you are gone, the more divergent your information.

Your transformation into a wash woman is nearly complete.

I’ve actually had a real life GPS outrage pre software update. I’d describe the event as benign as long as you get to .70M and 33k.

It was more of a nuisance and felt like driving one of those old style ladder trucks in Chicago with a rear driver (who wasn’t good).

Hardly what you care to purport.

Maybe you should take your big watch off and learn to really fly aerobatics. If you can’t handle a little Dutch, I gotta question your claim to be an “Aerobatic God”. More of a Tag Heuer Queen or a Breitling Showboat.

Some of are actually just flying really well without all the bedazzling social media buzz.

Nice watch though.
