The refurbishment of rotable components is important for aerospace companies, for which system availability is a critical factor, and for which rotables guarantee a high level of system availability. The refurbishment of usually high value faulty rotables is of considerable economic importance for companies, and is often a core process in plant maintenance. It is often much more cost-effective than a brand new purchase.

In aircraft or other technical objects such as engines, high value components are often used (such as landing gear) which, in a Remove-Install-Rework scenario, are replaced in cases of damage by a serviceable rotable and then refurbished at a later point in time using a separate order. In addition to the functions for Plant Maintenance, functions from Production, Inventory Management, and Materials Planning are also used for the refurbishment of rotables.

Our software solution enables rotables inventory management. It helps you keep track of the inventory information such as item name, total units, unit price and total value of the items. Space is provided for notes too. Locally save the inventory information as a file, and re-use it with minimal changes. Simply tap e-mail to share your files. Alternatively, you can email the file to yourself. A seamless app catering to your inventory management needs.

Further, our software solution enables you to keep track of where to keep your repair documents and for how long to keep them. Simply enter the document name, where to keep the document and for how long to keep it.  We have added simple sharing capabilities like email and print for all the sheets to help you make the efforts a collaborative endeavor.

We are also using Ethercalc ( for computation, collaboration and sharing of spreadsheet. EtherCalc is the spreadsheet equivalent of a wiki document, without logins and without editing locks. People can collaborate on a spreadsheet-like page simultaneously. It's somewhat a google sheet alternative, open source style.

Rotable Management Process
1. Procurement of new rotables - For certain critical and high-value components used in a technical system, we procure new rotable components to replace components promptly in the case of a breakdown.

We procure new rotables using Materials Management. We order the components, which are delivered to the serviceable stock warehouse, such as a central warehouse. We create a material or equipment master record for the rotable. If desired, the rotable can be serialized as an individual piece of material for the goods issue in the planned storage location, assigned to a batch, and valuated.
2. Exchange of unserviceable and serviceable rotables
3. Creation of the refurbishment order
4. Release and execution of the order
5. Withdrawal of rotables to be refurbished from the warehouse
6. Completion confirmation
7. Return of refurbished rotables to the warehouse - Updates:
Quantity delivered is displayed in the order header
Order obtains status Delivered or Partially Delivered
Order is credited with the value arising from the quantity delivered and the current price of the refurbished material.
8. Order completion
9. Order settlement

    Education Goals
    OLPC Localized Keyboard is useful only to the extent it is used by the learning community. Thus, we are working with educators around the world to focus on these learning challenges:

    To make OLPC Localized Keyboard and OLPC Localized Keyboard projects freely and readily available to learners everywhere
    To explore and share best practices
    To provide a forum for discussion and support for technology for learning
    To provide mechanism for evaluation and dissemination of results.

    Technical Goals
    OLPC Localized Keyboard supports the notions that learners should “share by default” and be able to “explore, express, debug, and critique.” Thus OLPC Localized Keyboard puts an emphasis on “activities” rather than “applications.” The foundation will focus on solving the challenges that are relevant to these aspects of the interface, namely:

    To make it “simple” to share OLPC Localized Keyboard activities. This will require an architecture that allows discovery of activities.
    To create versions of OLPC localized keyboard that run on multiple operating systems and on multiple hardware platforms. It should be “simple” to install OLPC keyboard everywhere. Specifically, it means packaging for every distribution and every virtual machine—removing hardware-related dependencies wherever possible.
    To make it “simple” to write Sugar activities. This necessitates stable APIs and example code that uses these APIs.
    To make OLPC keyboard activities even more secure. Our principal user community is comprised of children; they must be protected from malware, phishing, botnets, etc.
    Community Goals
    OLPC localized keyboard is here to support community innovation, entrepreneurship, and enterprise. OLPC localized keyboard would like to help community members start projects that help sustain and grow the OLPC localized keyboard technology and learning communities:

    To provide local and regional technical and pedagogical support.
    To create new learning activities and pedagogical practice.
    To provide localization and internationalization of software, content, and documentation.
    To provide integration and customization services.
