How do I tell the difference by just looking at these planes? They look quite similar to me.

The Way I tell them apart is by the engine intake. On the newer NG's the engine is less flattened on the bottom.

What I know is that the 737NG Family has a larger wingspan and a larger tail-fin.

I can tell by the length and by the amount of Emergency exits. For example, the 737-800 is alot longer than the 737-600. If all else fails then just read what kind of 737 it is on the side of it. Smile

Look at the back of the engine. In 737-3/4/5 there is a small cone in the back but in the NG's it is more like a thin needle that pops out.

Engine exhaust-seems to be a short pipe sticking out of the engine, as opposed to a cone-shaped structure on the classics.

1.Taller tail

2.Larger wingspan

3.Bigger APU vent

4.Rounded engines

5.Antennae close to nose cone.

These are the features of the 737NG Smile

.....up there with the best!

Yes, WN's 737-700's have red flap canoes. I think it's for maintenance.

And about those flap canoes. .. I know the -400 only has two of them while the -700 has three. . . anyone noticed that before?

If you're facing the aircraft head on, the engine on the NG's will be less flattened, and more rounded because of the aircraft's slightly higher ground clearance. From the side you can see by the taller tail fin (it makes the plane look shorter and stubbier). The wingspan is slightly larger, but it's kind of hard to tell that way.

Or just look at the airline that is operating it. A Delta 737 with 2 overwing emergency exits would be a 737-800 while any 737 in American Airlines colors would also be an -800.

You can tell from the engine. The B 737NGs have less flattened engines. Smile

- The engine exhaust plug is cylindrical end as opposed to cone shaped
- The tail is taller
- The wingspan is longer (additional slat on each wing - 4)
- The logo lights are no longer coming from the wingtip. (horizontal stab)
- Pitot tubes are now located just below flightcrews sliding window instead of behind. There also only 3 now as opposed to 4)
- With flaps down, you'll notice that they are now double-slotted, not triple slotted
- Inboard flap fairing on NG is point. Classic was flattened out to help form exhaust gates.
- Ldg lights repositioned to belly. No longer on flap fairings
- Taller main landing gear
- APU exhaust has a second hole right above it.
- Additional spoiler panel (12 as aopposed to 10)
- Engine appear longer than classics
- RED.green position lights are much brighter and a sharper

THATS EVERYTHING VISIBLE!!!

When all else fails:

Continental
B737-300
300 tail number
B737-500
600 tail number
B737-700
700 tail number
B737-800
200 tail number

Engines is the best bet. The tail cone is different from those of 737 classic.
