I have a commercial rating. The HN title is wrong.
What this is saying:
1) If you don't have a yaw damper, then you'll have a rough ride
2) because the autopilot will induce oscillation (dutch roll) after loss of GPS
- JshWright 10y agoThe HN title is literally the subject of the notice, very slightly paraphrased (abbreviations expanded, etc), so you may want to let the FAA know they got it wrong... I also think you misread the notice. The report is stating the loss of GPS apparently resulted in the subsequent loss of a number of other systems, including the yaw damper.
- throwaway_exer 10y agoI think you're right. The wording about "no yaw damper" would have been clearer as "failed yaw damper" - I guess that's what was meant.
- Filligree 10y agoHow much oscillation? On a scale from "bumpy ride" to "holy shit my wing's off".
- JorgeGT 10y agoDutch roll is characterized by a low frequency oscillation, with a period in the order of seconds. So it wouldn't be a "bumpy" ride but a slooow yet continuous, very nauseating oscillation (try to slowly rock forward and backward in your chair).
