Hello every one please help me on this question.

GIVEN: Empty weight (oil is included) 1,271 lb Empty weight moment (in-lb/1,000) 102.04 Pilot and copilot 360 lb Cargo 340 lb Fuel 37 gal Will the CG remain within limits after 30 gallons of fuel has been used in flight?

You should know how to do that calculation yourself using the W&B information for the specific airplane.

Probably. Give us the moment of the pilots, cargo and fuel like you did for the empty plane. Better yet, what airplane? Depending on how the cargo is ‘distributed’ you could have started out right on the edge of the ‘envelope.’ If so, burning off 30 gallons could put you out.

Hmmmmm this is very similar to that previous post... Yeah... and what @GRG55 said.

Are you a student pilot? If so, you should get with your CFI to learn how to do these calculations.

Sure sir
 
Build yourself an excel spreadsheet and play with every scenario. It's not that hard to do. You could purchase a weight and balance ap to accomplish the same task.

Shameless self promotion, don't watch if that bothers you:

Good initiative, poor execution. Get with your CFI, or any number of resources linked in your other threads.

My mom, an immigrant with broken english, when she was first pulled over in this country the police officer said to her "alright ma'am, I am going to cut you a break" - as in, let her go without a ticket. Well my mom (a) didn't understand the expression 'cut you a break' and (b) coming from a Soviet Bloc country assumed the worst and had a near panic attack that the cop was going to "cut her brakes"

It's a funny memory in hindsight.
 
i get paid 50/hr to give ground school. I don't do it for free on the internet. if you are a student pilot you need to learn how to W&B. either get a good instructor or enroll in a ground school. please don't ask other to do the work for you.

There appears to be a fair amount of required information missing. There should be position information for all loads in the airplane as well as the CG limit range. Since this is a question you are presumably working on, perhaps more information is available to you elsewhere?
 
At the risk of offense to some sensitive (beachcraft) pilots, some of the early V-tail Bonanzas will shift the cg rewards as the fuel burns off. Enough to take off in cg but be out of cg when landing.
The older written tests for commercial certificate used to reflect this, with questions directly from the sample w&b from the a/c manual.

Most of your garden variety Cessna and Pipers shift little if any, by design. Actually comparing my Cherokee 140, going from 50gal to 12gal shifts the cg 0.74” forward. An indiscernible amount.

The only way to know is to run the W&B problem using the aircraft manual. What I use to tell my students is compute the CG for takeoff then redo the problem with zero fuel. If they were still within the CG envelope then there was no issue. If they were out of CG in the zero fuel condition then I would have them keep doing it until they found the minimum fuel that would keep them within CG. For most conditions if they were within CG for takeoff they were also within CG with no fuel. Bottom line use you aircraft's W&B data and charts and run the problem.
