707 / 727 / 737 cockpit similarities

Sun Nov 19, 2017 5:10 am

They look identical at first glance. Any way to distinguish between these by only looking at the front of the a/c ?

Are you referring to the cockpit or the nose section? The cockpits of the 707 and 727 are largely the same other than the fact that the 707 has all the paraphernalia associated with having an extra engine while the 737’s cockpit regardless of generation is quite different. If you are talking about nose section, all are the same as you say so to tell the difference at first glance, glance at the rest of the plane and you can easily tell the difference even from a head on view.
Been on: 732 733 734 73G 738 752 763 A319 A320 A321 CRJ CR7 CRA/CR9 E145 E175 E190 F28 MD-82 MD-83 C172R C172S P2006T PA-28-180

2 ears for spatial hearing, 2 eyes for depth perception, 2 ears for balance... How did Boeing think 1 sensor was good enough?!

Isnt section 41 the same in all three types.
However the cockput/flight deck does differ a lot.... more so after the B737 classics wete built.
I may not win often, but I damn well never lose!!! ;)

Here is a good visual comparison B707 vs. B737. It shows how much deeper the 707 is underneath the cabin floor.

This plane is built to withstand anything... except a bad pilot.

At DL last week we had a ANG KC135R visit TechOps for Veterans Day. Standing in that cockpit the similarities to the modern 737NG are very striking.

There are a LOT of similarities between
those three aircraft, inside and out


Boeing really pioneered what was as close
to a common cockpit that could be found
in those days

Just to list a few:


Same windows, including sliding DV / emer
gency exit


Mechanical trim wheels with fold out handles to operate stab manually as a back up


Virtually identical instrumentation, such as
ADI’s, instrument comparator, engine instrumentation, flap gauges, fuel, oil, gauges, the pressurization panel on the 727-200 and 737 is identical


Throttles, speed brake, flap handle and operation all identical, rudder / aileron trim
parking brake, nose wheel steering tiller identical


Fire handles and operation identical, the list
goes on, many systems are similar between the three types, while there are differences any Pilot going from a 707 to a 727 / 737 was very comfortable


The 727 was a respectable advance in technology over the 707 with fully powered
controls, double hinged rudder, automatic
brakes on later models as well as fully automatic pressurization

The 737 wasn’t a big leap from the 727, basically the electrical system was updated
and automated to no longer require manual
paralleling of generators and the other systems were updated slightly and placed on the overhead to allow 2 Pilot operation
The best contribution to safety is a competent Pilot.

I recently sat in the cockpit of the MAX-8 and waxed nostalgic of the old 737-200s I used to fly. The family lines are clearly there.

I chuckled at a couple of the panels overhead that were directly from the old -200, (and probably earlier aircraft I haven't flown). One, even included the cutouts for gauges on the -200 that were no longer there!
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!

It's been many years since my 727 days but I remember the instructor, before computer learning,saying that the reason the 727 had the fire handles off set to the right was that it was essentially the no.s 2, 3, & 4 fire handles for the 707. Removing no.1 was the wheel well warning.

The 727 was such a basic, mechanical jet


There were so many noises going on, testing the fire warning you could hear the loops activating, turning on the packs on a cold morning you could hear a furnace like sound as it warmed up

On the before and after start the Flight Engineers panel was a blur of activity, lots of switching, activating and setting going on

Climbing to altitude there was often a ‘thump’ as the pressure differential increased, always accompanied by the trim wheel
whizzing around (not nearly as much as a 737 though) and of course the airflow noise was very loud



The gear handle was a great big, heavy lever with distinct detents, no delicate electronic switch here, you had to be very positive and somewhat forceful with its operation and other controls, it was a rugged, heavy duty aircraft inside and outside, very different from today’s aircraft


But what a delight it was to fly, very stable yet beautifully responsive with perfect control harmony, it was probably the most fun to fly that I’ve experienced, unforgiving on landing but if you got it right, very satisfying


And it went through turbulence like a hot knife through butter, I’ve not flown or rode on any other type that shrugged off bumps like the 727


The very flexible wing and high sweepback was just a superb combination



I like the modern aircraft, almost everything you want is handled automatically and the automation is really good (when it works)

But the 727 was my first jet and what a great way to learn, lovely
aircraft that will always have some of my best aviation memories
