D-plan / Libra is just fine as a helpful tool to an experienced Load Controller.
It offers a straight-forward, fast and visually helpful indication of weight and balance in real time. It is great in that you do not have to learn any stupid entries like Codeco etc.
If you want to enter the fuel figures for instance; you just go to the fuel page, by clicking on the fuel button.
OK, you can teach just about anyone to use it. But, it does help if you have some Load Control experience before getting your hands on it. IE. Being aware of what you can load in a particular hold of any type of aircraft and why you would load it it in a particular way.
You should not be using it, if you can't go to using a manual Load Sheet as back-up!
So used by properly trained staff; it is a joy to use and helps you to provide an optimum trim for efficient and safe flight.
Over the years, I've used many of the different systems and I've observed that most people are happiest with the system they first used and got to know extremely well. D-plan Libra is no different, and if you had never used anything else but Libra and then were trained to use KLM's Codeco for example, you would not believe how outdated and backward a step it would seem to have to spend a week trying to get to grips with such a rubbish system.
Although, many old hands, just love that old system!
