737-300/700 Differences

[Kanger]

Could somebody please help me out with the differences b/w the 737-300 & 700?

I've done a search already with no success.
TIA

Wider wingspan, (19ft?)

Taller tail (4ft?)

Landing/taxi lights clustered together by the fuselage instead of spread throughout the flap canoes.

Erm...overwing exits hinged at the top instead of being just plugs (maybe)

I think they might have a different flush system on the lavs too.


...but that much you probably already know.

-700 5 tonnes heavier, and more useful load.

-700 total EFIS panel, -300 has various instrument layouts, all with at least some round dials.

-700 cruises typically at .78, -300 at .74

[Kanger]

Thanks folks.
Any ideas about range?

Hi,

the -700 has a much greater fuel capacity (20+ tonnes) compared to around 14 for the -300.

It also burns fractionally less fuel per hour...... is the range is 50%increased or more over the -300

some -700's are ETOPS as well

Aren't Ryanair trying to obtain ETOPS certification for their 738's over the pond to NY/Boston?

[Onan the Clumsy]

It just doesn't seem right to fly the Atlantic in a 737.

[flash8]

If you didn't go great circle I'd assume it could be done now (without ETOPS certification) in a 737

As for flying ETOPS with a Ryanair 738 on an 8 hour flight with minimal seat pitch (and bring your packed lunch) rather you than me.

[The Greaser]

Yeah, but imagine a regular fare of maybe 100 quid return to NYC. I can manage 7 hours of discomfort for that.

There is no way MOL would ever try longer-haul flights --- the economics just don't work out. Sure, utilisation would be up, but that's about it.

Performance: Faster cruise M0.78, Higher ceiling 41,000ft, Lower take-off & approach speeds, Higher MTOW, lower fuel burn.
Engines: FADEC controlled CFM56-7, 2.5deg nozzle tilt, redesigned struts, improved nacelles with increased airflow and improved noise treatment, 7% more fuel efficient than CFM56-3.
Fuselage: Strengthened for increased tail loads and design weights, new wing-body strake.
Wings: New airfoil section, 25% increase in area, 107" semi-span increase, 17" chord increase, raked wing-tip, larger inspar wingbox with machined ribs, increased fuel capacity.
Tail: 4ft 8in taller, 60 sq ft root insert, modified rudder, segmented rudder seals, digital yaw damper.
Flight Controls: Increased elevator PCU capability, aileron and tab span increase, new double slotted continuous span flaps, new leading edge Krueger flaps, additional slat, additional spoiler.
Nose Gear: Stroke increased 3.5" to relieve higher dynamic loads and wheelwell extended 3" forward.
Main Gear: Longer, one piece titanium gear beam, 43.5" tyres, digital antiskid.
Flightdeck: 6 programmable LCD's, replacing EFIS CRT displays and most conventional instruments.
Systems: Most systems developed particularly: electrics, powerplant & navigation.

On the downside; the flightdeck is noisier, it is not as nice to hand fly, the wings frost up if you arrive with too much fuel, it tends to overspeed if you are descending from above FL390 and the nose gear is more prone to shimmy on landing.

Apart from that it is wonderful, but so it should be after 40yrs to get it right!

A lot longer range, bigger fuel tanks, taller tail. Just to name a few.

Thanks fellas
cheers

And a tiny warning light saying "PSEU".

Caused already lots of confusion if there's not enough documentation or maintenance at hand!

Better APU, recommended practice to use both packs; great stuff!

[IFixPlanes]

Another difference:
2nd Battery
Overwing exits hinged at top (you are right Onan :ok: )
almost every System has been improved.

@ superpilut
Yes, the PSEU light is tiny, but very important.
If you can reset the LT with MCR you have a "dispatch Fault" (you can dispatch):cool:
If you can´t reset the LT with MCR you have a "No Dispatch Fault" (stay and call engineer) :{

P.s.: If you need more Info about PSEU -> send PN
