If you know the weight of the oil and the arm of the oil sump, just do the math. IMHO.

The sheet calculates a number of common scenarios and allows for the user-entering of various parameters such as pilot weight and plane weights as well as the various arms. Its setup for an RV-8, but could very easily be modified for other models of RVs. After I finished it, I thought other builders might like to use it as well.

Excellent use of "Conditiona l Formatting". Be advised that the FAA only needs to see the following: Empty Weight calculations. Gross Weight CG Calculations. Most Forward CG Calculations. Most Aft CG Calculations. First Flight CG Calculations. All the above must be at or within CG limits. DO NOT show the FAA any calc ulations that are OUTSIDE limits. As the builder=2C you set the gross weig ht but it is advisable to follow the designers numbers. IF you end up with a gross weight that is greater than what the designer set=2C know that you are operating outside the design envelope. As you already know=2C you must carry a copy of the weight and balance in t he aircraft and make it available for any ASI that asks to see it. If you use the WORST CASE loading for the above conditions=2C you have a "Go - No Go" bracket for any flight. Yes it is still good to know EXACTLY the loadin g but for a "Ramp Check"=2C the above minimum is all the FAA needs to see t o verify that you are operating safely. The above will also print out neat ly on one piece of paper if you use both sides. I would like to advise that you only give the FAA exactly what they need. Giving more than is needed could open you up for a lot of extra questions f rom the inspector. Gary A. Sobek "My Sanity" RV-6 N157GS O-320 Hartzell=2C 2=2C346+ Flying Hours So.

Greetings: I have time to help someone on their Project. I have completed building the RV-8A empennage ( Acid etched, Alodined and Mil Epoxy Primed the interior skins and assembled) and have run out of room to continue building. Have tools to help someone on their Project. I am a retired electrical engineer and have designed my own Electrical System for the RV. Also designed an "Pilot Aux Warning System" that monitors Vans analog engine gauges and provides a Warning for - "Low Fuel", "Hi Oil Temp", "Low Voltage", etc Spent many ours researching the best way to do things on Matronics from other Builders. Hoped to use this info on my Project, but ran out of room to build, thus hoping to share ideas and help someone on their "Project".
