Does anyone get the marker sounds to come up?
Edited:

Thanks, Ron.
Short questions lead to short answers, huh?  

I'll have to check my sounds, maybe I'm to busy on the approach, so I don't listen.

Ah, seems like we're collecting the guys with the short statements now.   Just kidding.

Pete, how do you achieve the equally dumping fuel on the plane? What's your setup there?
Currently, I only saw reports about one side getting dumped while the other half of the plane stays full, leading to a big imbalance.
So what's your secret there? Thanks for your input.

Thanks for answering, Pete.

I'm running onto two problems when talking about the current fuel dump procedure.
First, I think that the Center Tank has to be the first one to get emptied, just because it's the last one to be filled. Later on, the 2&3 mains have to follow, until they've reached a certain level where their fuel equals the amount of the outer 1&4 + Reserve.
That's the schedule you have to follow when just burning fuel on the 707. Why alter it when dumping?


Second, the unequal dumping produces large imbalances. Look at the gauges. If Tank 1 goes empty while Tank 4 stays full (this currently happens), you'll get 15.000 lbs of imbalance.
Later, when Tank 2 goes down and Tank 3 stays full, you'll earn 27.000 lbs. That's over 12 tons!

Also, since the plane is meant to feed its engines from Tanks 1,2,3,4 (=Mains) until the end of the flight, this dumping might lead to starving engines, because the current process gives you a full Center Tank but empty mains and wings.

Here are some docs where the fuel setup for burning fuel and also for filling your tanks is described. All of them show the importance of no imbalance and also the one of the main tanks, which are 1-4.



Still convinced that the fuel dump works as intended? 

I'd say so too, although my experience doesn't even come close to yours of course.

I've searched the AOM for the dumping process and this is what came up there. Looks like a very equalized operation, leading to a fuel loss like it would happen when just burning it.
One would have to make sure to open the Center Tank valves first to allow this huge reservoir of fuel to get empty first.
Later, Tank 1,2,3,4 can be opened and would run down at the same rate, like on engine operation. Reserve Tanks, as seen in the marked text, can't be dumped at all.

Currently, the Reserve tanks run down first.

Here's another drawing, so everybody can see what we're talking about.



Any comments on the remaining items? Do we agree that e. g. the working pressurization would be a huge step into the right direction?

Agreed, Lou. After the "runway height" measurement and the operation until 20.000ft until version 1.2, we now have a dead needle in 1.3.
