Things you should have

YOU said 718 AND 787! Hey, we agree on something.

I have both. Just because I want to.

Who in the HELL said anything about using another Models data? 787 Covers D thur M10sRead the Dame TCDS We are not talking about putting a DC3s to a 415 airframe here...718 Cover both C AND CD... I guess I needed to say your TC!  or I am too anal!

Only problem is if you use info from aircraft you don't have you render your aircraft unairworthy. Part of definition of 'airworthy' is that Your airplane meets the specs for YOUR airplane. Not one similar, but one manufactured to YOUR TCDS. Other TCDS doesn't count no matter how similar it is. If you own an ALON you MUST use the Alon TCDS. If you own an Ercoupe you MUST use the Ercoupe TCDS. Otherwise an unairworthy airplane!

Easy to answer. The data within it! From adjustments of controls to storage lbs that you can load. If you put a 9 cu ft in you are still limited to the given lbs.

Why would you need the TCDS for an aircraft you don't have?
