What is a Likert Scale vs. a Likert Item. A âLikert scaleâ is the sum of responses to several Likert items. These items are usually displayed with a visual aid, such as a series of radio buttons or a horizontal bar representing a simple scale.

Flight controllers are personnel who aid space flight by working in such Mission Control Centers as NASA's Mission Control Center or ESA's European Space Operations Centre. Flight controllers work at computer consoles and use telemetry to monitor various technical aspects of a space mission in real time.
By Clym Montgomery June 3, 2014 5:00 AM. Most flight controllers do not present the corporate, mass-produced feel of the Nazas. One of the many success stories to arise in the multi-rotor market is OpenPilot, an open-source community dedicated to perfecting flight control algorithms. There are various OpenPilot flight controller boards available. The CC3D is one of the most favored. Thanks to OpenPilot, it too is relatively easy to set up, leaning on a software wizard to configure the board, step-by-step. It features multiple flight modes, including self-leveling and completely manual input. It lacks the autonomous natures of the Naza, as well as GPS lock.
