When, if ever, did the 767 move to floatsticks?
I would assume that all variants of the B767 came from Boeing with “dripless” fuel measuring sticks.
The final accident report you referenced states that these measuring sticks are designed to be ...

What are the "Static Ports" in a Boeing 767?
The airplane instruments that need barometric data, airspeed, altitude, vertical rate and all that, need to have a connection to the atmosphere that reads the true ambient air pressure unaffected by ...

How can tailplane force imbalance twist a tailcone off?
In most of these airplanes the vertical fin is attached to lugs along the upper skin and frame structure and to the bulkheads at the front and rear spars of the fin. Overloads will tend to break the ...

What was the value proposition of the 767-400ER over the 777?
It's pretty clear that operators of the 767-400ER knew what they were doing when they selected that aircraft. Only United and Delta bought them and they are still in service even as older 767 models ...

Did any Boeing 787 operator achieve the 20% fuel efficiency improvement over the 767?
A Real-World example:
On a typical 3,551 NM airways distance flight a 365,000 lbs 767-300ER will take 08:40 and 92,300 lbs of fuel to get there with 216 pax and baggage (no cargo). The flight took ...

767 fuel line issue
TL;DR: Large aircraft normally isolate the left and right fuel systems, so if engines start, you have enough accessible fuel to take off and divert or return. There is also a cross-feed mechanism to ...

How did the 767/757 reduce fuel burn relative to older aircraft (like the 727)?
Your Norris source states most of the aero improvements came from the wing.
The airfoil mentioned has a supercritical section. Below is a typical supercritical section compared with one from the 707. ...

How much pressure do boost and jettison fuel pumps produce?
I looked up a cannister boost pump and jettison fuel pump on the Eaton website and found a cannister boost pump for the 747 that puts out 28,000 Pounds Per Hour, and a jettison pump also for the 747 ...

What is the difference between flap load relief protection and overspeed protection?
According to this document/study guide
Flap Load Relief – on the 757 and a few 767s, if the flaps are at 30
and Flaps 30 speed is exceeded, the flaps automatically retract to 25.
On most 767s, ...
