Finally after two years of working in secrecy I can show you what I’ve been designing: the Cessna Citation Longitude

Looks rad!

Cool, do I get a friends and family discount? Or are we not cool enough for you to make that happen for me? :P

You shouldn’t have told us, because now we expect a full road test.

Looks like an excellent aircraft. I don’t know the BizJet market very well, but the extended range definitely seems like a selling point. Going from 3k to 4k+ range brings a lot more destinations into reach. Not going to try to make the math work to determine burn per hour, but it looks pretty competitive, eh?

Congrats on the announcement. I’ll probably never fly one or fly in one, but if one burns through my airspace, or I spot one in the area, I’ll have a good chuckle. 2019 seems like a long way off, but I guess it’s not...

Do you need to get a Cessna Citation Latitude for north/south capabilities? #DadJokes

You should give me one for free just because.

Awesome! What aspects did you design ?

That's awesome! What part did you help design?

Very cool. Looks like some good specs. The cabin altitude is a nice touch that I hope people appreciate. Does it use conventional aluminum materials for wings and skin or is it going carbon?

2019 is Hemisphere. Longitude is scheduled to enter service in 2017

I work on the airframe for the empennage, specifically the vertical fin.

I design the structure of various parts of the tail.

Hopefully I can hitch a ride on a test flight at some point, so I'll give impressions then. I went for a flight on a Sovereign a few years ago, it was sublime

I'll give you one for free if you give me like $25 million

I’ll give you some spare change, the half empty pack of gum in my center console and a Iphone 4s charging cord that doesn’t work, but I still have for some reason.

Wait, you work at Textron Aviation!!!??? I applied there a month ago. Haven’t heard back. :-( I also am trying to apply to the Engineering LDP program but I cant find the link for the app or get an HR contact to see why I can find every department but engineering.

Cool stuff! I just saw Textron Aviation CEO Scott Ernest on the news today talking about the Citation and Longitude. It is a really cool plane!

Cool. Carbon is all well and good, but Aluminum alloys are pretty advanced in their own right. I know the C Series went with aluminum lithium and that is a bit out there.

That’s so cool. Are you anaeronautical or a mechanical engineer (or something else)

I should totally pick your brain on a few things.

My degree is Aerospace, so I consider myself an aerospace engineer.

Aluminum lithium is going to be big, but it’s new enough to introduce some risk. Aluminum is proven, and as a company that’s been making jets out of aluminum for nearly 50 years we’re pretty good at it. I don’t want to say too much for fear of getting myself in trouble, but there’s a lot of new processes and designs at work in the structure that really makes it quite a significant improvement over our legacy structure.

There’s some composite structure on this plane, and I wouldn’t rule out major composite structure in the future, but with our rapid design cycles aluminum is usually the low-risk baseline option.

Lol who designed this cruddy interior? GM?!

Chintzy tasteless pillows

Cheapest/Crappiest Screen they could find

Obviously fake “wood”

Fisher Price seats

That’s not the interior, this is

You found pictures of the old Longitude mockup.

Damn that’s dissapointing. The pics I found were actually pimptastic as all get out. Production is kinda bland in comparison

I’m curious- how much of the aircraft is riveted vs how much of it is welded?

One of the other things I have been wondering is the structure of a car’s A and C pillars in relation to how an aircraft is designed. It’s a bit hard to explain, and typing on my phone is slow. It seems like most aircraft are designed around a series of formers (for lack of the correct terminology). I’m curious why more cars aren’t built with a sort of oval former running from the A pillar to the C pillar on the opposing corner, making a criss-cross on the roof and floor of the vehicle. I’d think that such a design would lend itself to a more rigid A and C pillar. Again. Hard to describe while typing on a phone. I’m sure engineers have it all worked out the best way, but I’ve been toying around with the idea of a Scamander RRV shaped vehicle, and wondering how the frame underneath is designed. (I tried to upload a photo of the Scamander, but it failed on mobile).

Did you actually design this plane? That’s super cool.
