Dumb airfile question...

To all,

There's someone who has to know this...

How do you add droptanks to an airfile? I have it in the .dp, but I need to tweak the airfile so that it recognizes and accepts the droptank. How do I go about doing this with AirEd?

Thanks in advance,
 
Rami, It is available indeed.

I have it saved it is line 525 and 526 I think.
I will look and be right back.

sent it in email to you.
could not figure out a screen shot to post here.

In Aired, add 534 for a single ventral tank; add 534 and 535 for dual wing tank config. Copy these from another plane's air file and paste into your target file. Adjust the capacity and offset locations to fit your target's specs.

Okay, I have added the correct fuel capacity in gallons...(600 liter ferry tank)

Now, how do I handle the "offset"?
 
The offsets are the virtual locations (Lat, Vert, Long) of the tank(s) with respect to the dead center '0' reference datum mark of the model. All values are in feet. As capacity directly affects weight, locations affect CoG balance and thus overall performance. Two wing tanks located too far out on the wings will slow roll rate well below historical specs. If located too close in to the centerline, these tanks will have absolutely no realistic affect at all on roll rate.

Your posted offsets look about right for a single ventral tank Rami.
 
Still not working....dropping the tank doesn't affect the fuel. :crybaby:

What do I need to do?

Rami, in my mind that reply can mean several things. Can you be more specific as to exactly what's not working?

If you set up the Fuel tank number as number 5, as it should be based on your pic, then dropping the tank while flying with your panel's selector gauge on "droptanks" should result in an automatic fuel shutoff and kill the engine until you select an internal tank from 1-4. All this assuming you are NOT flying on "auto fuel management" in Settings.

Obviously you won't notice a huge difference in weight performance (this is a retail sim remember), but you will experience a fuel cutoff.
 
What I mean is that carrying the drop tank does not allow for greater range. On manual fuel management, if you switch to the drop tank, the engines cut out.
 
It may be working....

...Takeoff with full tanks and the auxilary tank. Fly until your fuel has dropped below 100%....say 98%. Select and drop the tank. If the tank is working, your fuel will read 100% again....since you were burning the auxiliary tank first. :engel016:
 
I flew the exact same mission with and without the drop tank. It cuts out at the same point in the mission. This tells me that the drop tank is not working. If it were, I would have plenty of fuel left.

Tango....I tried that, no effect.

Doesn't work that way TR...In auto fuel mgmt mode, the sim code burns the primary internal tank first (usually number 1) then moves down the line, unless you select the drop tank which interrupts this sequence and prioritizes the DT. Internal auxillary tanks are always touched after internal primaries are depleted.
 
Well, the drop tank works, but it does not extend the range when warping from Alexandria to Malta. You still run out of fuel at the exact same spot...about 70 miles ESE of Malta.

The easiest way to explain it is that I can USE the drop tank, but it doesn't count as part of the total fuel volume when I warp from one waypoint to another.

If I were to switch it to Bruce Thorson's P-40c conversion, after warping to Sidi Barrani, my fuel level, with drop tank included, is at 85%. If I were to RELEASE the drop tank, my fuel level in the HUD jumps up to 99%, indicating that I am now running on internal fuel.

This "reset" does not exist in the Beaufighter, which tells me that although I can SELECT and USE the drop tank, using it does not increase my total FUEL VOLUME when warping.
 
That would be correct...

You start on your droptanks, but you have to drop them manually to get back to the mains. That won't happen automatically when you warp.

BUT the big question is are you talking about with AFM on or off?

And I have all my UNKNOWNs in 534 set at 2. Got a couple of dozen airplanes flying around out there with working droptanks???????

AT ANY RATE, I hope you get it sorted. Didn't mean to butt in....I'm swearing-off.
 
Bearcat...I updated that post. :redf:

Sorry, a little unnecessary confusion on my part. I'm still having trouble. :banghead:

I put in a help flyer to Peperez, he's the architect of the new aircraft.cfg and airfile.
