Cessna 408 SkyCourier
 
Looks like they bred a BE1900 with a DHC8.
Then again maybe it's a westernised LET410 :}

Anybody found a MTOW for it?

Global Aviator 29th Nov 2017 16:27

Looks like a bit of a hybrid from everything.

The question is...... expected cost?

Sounds like good speed when put next to the Viking.

Now a float option would be sweet!

Whats is interesting is the choice of engines. Seams they gone for the pt6. Had they gone for the GE it woyld have been a game changer for GE. Fedex was the reason forthe pt6 to get the single engine ifr charter certification. Had they gone with ge and proved its reliable would have give ge some extremly strong data for the same

I did think Nomad!

Engine options.


Pressurised & non-pressurised.


Floats/ski's.

Wunwing 30th Nov 2017 00:18

Why wouldn't they use a PT6? Its clear from the press release that the project is built around the FedEx order and FedEx and its associates has a long history of using PT6 powered aircraft.

The transition period of the new aircraft coming online to current PT6 operators alone would justify a common engine type.

So, P&W got single engine IFR certification due to the record of single engine IFR operations on the caravan with FedEx ... Taking that at face value, how would putting GE's engine on a multi-engine airplane help them gain single engine certification?

OZBUSDRIVER 30th Nov 2017 03:52


The PT6 family is known for its reliability with an in-flight shutdown rate of 1 per 333000 hours since 1963,[6] 1 per 651,126 hours over 12 months in 2016.
It isn't rocket science to work out reliability in a multi and calculate risk for single engine IFR applications.

Because the engines are independent of each other. Plus the bonus of ever 1 hour flyi g time you are getting 2 hours of reliable record. So in fact it can be shown in half the flight hours as againts to 208

Over 12 months ago the pt6 seris had over 550million flight hours in service.

ASEPTA approval in Australia is based on engine/airframe reliability not just the engine. Think you will find that some C-208 variants aren’t ASEPTA approved in Australia (yet), Caravan EX maybe? Other types such as the PC-6 won’t get a lookin without reliability data.

lo_lyf 30th Nov 2017 08:36

ASEA is such a joke. Just approve anything with a PT6.

Yes. You can make any caravan complaint with the mods. The aircraft is in tne consideration but ghe main thing is the thing at the front converting liquid into noise.

Weird looking props?

troppo 30th Nov 2017 09:21

GE vs PW argument aside, there are some potential uses for it. Payload is on par with DHC6-400. Faster cruise but takeoff distance handicap. Pacific Islands over water uses spring to mind.

LeadSled 30th Nov 2017 10:01

Folks,
Looks like it will be the first aircraft to be certified under the new FAR/EASA 23.
Be interesting to see if the rather radical new system will work, probably beautifully, as CASA are already saying No!

Tootle pip!!

Duck Pilot 30th Nov 2017 10:57

Particularly if it's certified for 19 seats Leadie, Kiwi regs would fix all this - BUT WHAT WOULD WE KNOW?

LeadSled 30th Nov 2017 14:04

Duck Pilot,
Exactly!

It is what it is, with design probably very strongly influenced by a FedEx requirement. The FedEx current and future orders would justify production.

Not the first proposal in this class of aircraft but this may be the first to actually be built. "Wizard" aka Flukey Luke was also pushing a similar type but larger aircraft some years ago, stating, with his usual impeccable honesty, that he's bought a couple of hundred off the plan! It was the Utilicraft FF-1080, twin PW150s, 20,000 kg disposable load, single pilot, which it appears never progressed beyond a wet dream. I'm not sure how they thought twin PW150s would push a 40 ton aircraft to 250 kts? :}

I suspect this aircraft will feature strongly in FedEx hub and spoke feeder operations in the USA. The PT6 is ideal for this purpose, despite the probably high cycles.

I suspect it will struggle as a commuter, for the same reason the Shorts SD3-30 and SD3-60 struggled, speed, lack of pressurization and payload/range limitations.

Same pax capacity as a Twin Otter for around 40 kts (25%) increase in speed but loss of STOL ability? Interesting the choice of a couple of 1,100 HP -65's to carry 19 pax, versus two 650 HP -34's on the DHC6-400. The Beech 1900D has similar engines, same pax capacity, pressurised but 50 kts faster.

TBM-Legend 1st Dec 2017 07:47

FedEx will ultimately buy around 250 of these. They know what they're doing in the freight world.

Petropavlovsk 1st Dec 2017 07:57

Importantly, Cessna should make sure the aircraft can perform in ISA +20 degrees and high altitude airport capability, preferably at MTOW. That would be good!

TBM-Legend 1st Dec 2017 08:15

It's what will work for FedEx. They have operations in Colorado 5,000msl and ISA+20 in summer..

On eyre 1st Dec 2017 21:51

A modern Bandit replacement.

PLovett 1st Dec 2017 23:02

Mmmm...............I wonder what its ice-carrying capacity is going to be?

TBM-Legend 2nd Dec 2017 00:25

Better than a Caravan I'd imagine..

Would be nice but a bit of a handicap on fuel flow for the same number of seats and not a lot of difference on book values with speed.

Uhhh, yeah, but the Bandit can't carry 3 LD3 shipping containers, which I expect, is a lot more relevant to Fed-ex and Cessna than how if compares to the Bandit as a passenger hauling machine.

Duck Pilot 2nd Dec 2017 05:53

Is it going to have a ramp door like the CASA 212?

A Squared 2nd Dec 2017 05:57

The drawings I've seen show it with a large aft side door that the containers would slide into sideways then get moved forward, so, no aft ramp.

That's good. We agree that it's not a Bandit replacement then :p

I reckon they could get a few more knots out of it by streamlining the front end a little. It's pretty square and old-school looking. Looks like an EMB110 or worse.

On eyre 2nd Dec 2017 08:33

SWTT - there was nothing wrong with an EMB-110 in it's time. Made me my retirement fund thank you.

Guptar 2nd Dec 2017 13:04

I'm sure the nose of the 408 is exactly how they want it, despite the input from the know-alls on Pprune. After all, they have certified more designs that any other manufacturer on the planet.

Might have to do with the fact that it's designed around 3 LD3 shipping containers, which are kinda square.

There's no shipping containers in the cockpit.

Seems they pilfered the design from another well known company.

Well, no, there's not. But there are shipping containers immediately behind the cockpit. If the fuselage necessarily must have a large, rectangular cross section 6 inches aft of the pilots seat, there's probably not much point in making the cockpit narrow and sleek like a Learjet.
