Yes what you ask is definitely possible.
You need to do the following:
Flight Plan: Ensure the flight plan accurately reflects what you expect to do. So you should have a STAR and an approach to the runway in use. Presumably the hold will be on the arrival in use. If it’s not then enter the hold, followed by a discontinuity in the flight plan (enter any ...

(I just came up with this, so it may not be the official solution - but it should be fairly simple this way)
You first need to know the fuel you need for the diversion with all safety requirements included. This is computed like normal using the MCDU, EFB, etc.. I'll call this your "bingo" fuel. You just need to add the fuel required a 10 minute ...

Alone in an A36 Bonanza from central Florida to North Central Indiana, I flew on one load of fuel by decreasing the throttle gradually as I burned fuel to maintain a constant airspeed. The aircraft wanted to speed up as it lost weight. So, yes the aircraft will fly differently as the fuel is used.

Modern gliders are an interesting data point regarding this. A competition glider carries water in its wing tanks to increase weight. This betters performance at high speed, which is essential for competition when conditions provide strong lift.
The pilot can release the water at will, and the tanks can be emptied in a few minutes. This happens in ...

Something else that changes with a change in CG and/or weight is your stall speed. There is a good article from AOPA here: https://www.aopa.org/news-and-media/all-news/2020/march/flight-training-magazine/aerodynamics-stall-speed

All aircraft are subject to performance changes due to fuel burn, and since weight, lift, thrust and drag are all tied together for every aircraft in the same way the changes scale nicely. Let's look at some extremes:
One of the most interesting examples of this was the Concorde. Since the Concorde flew ~20K above every one else in the sky in those days it ...

Aircraft performance does change with weight. Not only does takeoff weight and balance need to be considered, zero-fuel weight and balance does as well. Many key performance metrics depend on this, like takeoff and landing speeds and distances. Climb performance and range are also affected. Inflight, Va (maneuvering speed) is very dependent on weight. The ...
