Check out the!Rules. Read the before posting. Certain questions, such as 'how do I become a pilot' and the like have been asked repeatedly in the past. Refrain from posting anything that does not pertain to pilots, students, instructors or other aviation professionals.
Post something that you would like to discuss! If posting a photo, video or link, you must include a relevant top-level comment to start conversation. For example, tell us how your checkride went instead of just posting a photo with you in front of an airplane, give your take on the article you are linking to, or ask a question about a procedure used in the video you’re posting. The title of your post does not satisfy this rule, write something in the comments!. PLEASE no memes. Is a meme-free zone.
Cite sources when appropriate. Posts about the non-aviating aspects of airlines (planespotting, passenger experience, frequent flyer programs) do not belong here.

This includes requests for donations. As a reference, it's good for pretty much everything exept weight and balance calculations. You should use the numbers that are in the AFM that stays with the plane, because they're the most accurate. They take into account recent measurements for that specific plane, while a POH will just give you factory standard numbers.You can use the POH for rough calculations as long as your plane doesn't have some weird modifications that throw the empty CG off, but for accuracy and legality you need to use the tail-number-specific numbers from the AFM.For older aircraft that don't have an AFM, you should still look into its records and find the latest W&B numbers and use those. Don't just use the POH numbers on good faith.

I believe my plane currently weighs 50-75 pounds more than the factory POH numbers. Just make sure you're using an official AFM when you do this for your checkride. It's a recipe for a failure if you can't show that your W&B calculations are spot-on legit. I had to show the DPE exactly where I got every figure.You can learn to do W&B with unofficial stuff like a standard POH for your model, but every single plane (literally every single individual plane) has a slightly different weight and CG because they all have slightly different equipment that weighs slightly different amounts. The MX crews are required to keep a running log of every single modification made to the plane (along with other maintenance logs), and you need to be using those official weight logs.It might seem silly & pedantic, but there have been in the past where people were 'close' on their W&B calculations, only to find that 'close' doesn't help you when you discover that you don't have enough elevator authority to get back to level after takeoff due to your CG being too far aft, especially if you're unlucky and your elevator rigging is slightly out of specification.
