How can Weight and Balance information be obtained on board a glider?

Weight and Balance information is essential for safe glider operation. The correct choice highlights that this information can be obtained from placards or the glider operating manual. These resources typically display important data regarding weight limits, center of gravity (CG) ranges, and loading procedures specific to a particular glider model. Users can refer to placards that are often located in the cockpit or consult the operating manual, which is designed to provide accurate and model-specific guidance to ensure that the glider is loaded within safe limits.

While instructors can provide valuable information and guidance, relying solely on an instructor does not ensure that all necessary information is readily accessible during every flight. Online apps or software may assist with calculations or provide supplementary data, but they should not replace the official documentation that comes with the glider. Weight scales in the cockpit are not a standard feature found on gliders, as they typically do not have built-in weighing systems; instead, weight calculations are performed before flight to ensure proper loading and balance.

Overall, relying on the glider's placards and operating manual ensures that pilots have the most accurate and pertinent information to maintain safety in operation.
