Error with EC 135 P2 and feature request

[wlbragg]

I experienced some issue with EC 135 P2. Since other helicopters work- even the H135 which is based on the EC135 P2 and I do not see any difference, there is must be something I did wrong.

No, some how missed it in the aircraft.xml definition. Once I push the changes it should load by default to the correct settings for an external winch on the right side.

Many helicopters in FGFS (YASim at least, maybe JSBSim) has hitches defined- for longlines and winches. They can be easily read out in sim/hitches

That is for aerotow, but I suppose it could play a part in the Cargo Towing Addon. Maybe it should. I'll look closely at that in the future.

But the way it is working right now is I actually read all the loadpoints and you have the option to use any of the existing load points, you can choose which one to use. I may be able to include the aerotow if it turns out it is a proper thing to do.

For example, the EC 135 P2 in fgaddon, freshly updated through the qt-launcher.

These are the FDM defined mass and weight points...

These are the defined weight points in the .set file that I automatically read in the addon...

		<weight n="0">
			<name>Pilot</name>
			<weight-lb>180</weight-lb>
			<max-lb>300</max-lb>
		</weight>

		<weight n="1">
			<name>Co-Pilot</name>
			<weight-lb>180</weight-lb>
			<max-lb>300</max-lb>
		</weight>

		<weight n="2">
			<name>Right Passenger</name>
			<weight-lb>0</weight-lb>
			<max-lb>300</max-lb>
		</weight>

		<weight n="3">
			<name>Middle Passenger</name>
			<weight-lb>0</weight-lb>
			<max-lb>300</max-lb>
		</weight>

		<weight n="4">
			<name>Left Passenger</name>
			<weight-lb>0</weight-lb>
			<max-lb>300</max-lb>
		</weight>

		<weight n="5">
			<name>Load</name>
			<weight-lb>0</weight-lb>
			<max-lb>800</max-lb>
		</weight>

You can choose from any of these. The addon does pick on for you as default in the aircraft.xml file and configure the hitch and rope to match. But I think the aerotow point might also need to be included. It depends on what it is there for though.

I'll let you know when I push some changes I'm working on.

@HHS81
OK, I think I got it fixed. There were a few different issues that had crept into the code. I still have some testing to do to verify several changes and bug fixes are good.
Please clear your aircraft data cache and pull the addon changes.

@wlbragg No, now none of the helicopters is working....

@HHS81
OK, missed a code block that needed some changes. Should be good now, need to pull and clear the aircraft cache.

Now it works great! 👍

@wlbragg Some minor issues:
1.) the EC135/ H135 needs a different point for the longline. Winch and Longline has each different position. I can give the point for the longline

2.) some weird angle of the Cargo - without wind, without any movement of the helicopter hovering

Otherwise I like it!

I can give the point for the longline

Sure.

some weird angle of the Cargo - without wind, without any movement of the helicopter hovering

Yeah, there are quit a few minor glitches that need attention. Once I get things stable that is the next step, try to clean up animations and other stuff. If you look closely you'll see a few glitches.
A major one is the rope once connected to cargo, it needs to be mostly rewritten. It's far from natural and the physics are off. It acts more like a poll and less like a rope.
