Re: Flydubai Flight 981, 737, Rostov-on-Don, Russia

Electric trim control uses two switches. Both must be activated in the same direction to get trim motion, in order to reduce probability of an electrical short or jammed switch causing uncommanded motion.

Re: And, in other news USA TSA is apparently setting some new records for line waits...

Flew through DTW on Monday morning. 10 people ahead of us in line. Took 25 minutes to get through, including a special examination of my keychain after they spent 10 minutes doing a bomb sniff on grandma's purse in front of me. Half of the 10 or so agents present were just standing around, doing not...

Re: WHY are two autopilots required for a go-around...

Dunning-Kruger strikes again! Thanks for the edumacation, Evan. My 6 hour seminar on autopilots was rather generic it seems, and geared mostly around FBW. Agreed, redundancy seems to be the real reason. Gabriel is suggesting stupid "what if" scenarios again, but to his credit I will say th...

18 months ago I got meself a 2015 jeep Cherokee trailhawk v6 9 speed auto. Overall mostly happy and nice on the forest roads. Haven't tried any real off roading with it. Decent highway gas mileage, considering (upper 20s mpg). The rotary knob for 4wd is a little less thrilling than that "clunk ...

Re: Flydubai Flight 981, 737, Rostov-on-Don, Russia

I experienced somatogravic issues during my most recent missed approach in IMC in the 182RG. Everything felt and sounded fine while I was fiddling with the radio and when I resumed my scan I was leveled off and accelerating instead of climbing at Vy. Contributing factor was probably that this was t...

Re: What were those aeroengineers thinking?!?!?

If you re-open a cross feed valve, you over ride important fire systems? How non-intuitive! What were they thinking? I would have designed it differently! A "Perf" option on the autopilot that has 100 feet of slop? That won't work! What were they thinking? I would have designed it differe...

Gabe, you're partially correct. It's both. I'm not going to get into the weeds on a complex airplane system that was designed over twenty years ago (even if I could share such information), but are you familiar with "Fail active" versus "fail passive"? You are correct that redund...

Re: WHY are two autopilots required for a go-around...

Anyway the reason two autopilot channels are required to transition from approach mode to go around is that when you advance the thrust for the go around there is a very large pitch up moment and a single channel would have insufficient nose down elevator authority to counter it until sufficient nos...

Gabriel, where do you get the idea that you can go below 200 ft on a single channel? For example, same link as before. Where do you get the idea that you can't?
