Hi Johnny, also another welcome to the forum.
Both laptops would likely be considered in the range of Minimum system requirement to run a Flight Simulator.
They will be able to run a Flight Simulator, however likely performance will lean towards the below average level side.
With the Dell spec's leading over the HP spec's. Now depending on the age of the Laptops you may see a Label on the outside of the Laptop like NVIDIA GeForce this would indicate that the Laptop has a secondary discrete intergrated NVIDIA GeForce GPU inside.
To confirm if this is the case try and locate on each Laptop the Device Manager
(right mouse button click on the Windows 10 Start symbol pane bottom left corner of screen) open this up and then locate Display adaptors
expand this down, you may see Intel(R) HD Graphics 620 that will be the primary Graphics Processor Unit GPU
If you see something like NVIDIA GeForce GT ??? underneath then you have a secondary High Performance NVIDIA GPU Processor, that you could potentially use as a preferred graphics processor for running a Flight Simulator program. If you have this in either of the Laptops you would need to located the NVIDIA Control Panel to manage 3D settings for some tips watch this youtube clip Nvidia Control Panel Best Settings for Gaming and Performance Guide 2020
Depending on where your starting at as a Rookie Flight Simmer, you will need to consider and investigate what Flight Simulator you want to use. A brand new Microsoft Flight Simulator is currently in development and is expected to be available later in the year. You may wish to wait and leave it for now, perhaps look at upgrading to a gaming laptop or desktop PC in the future.
If your looking for something right now to get started. You may consider the current stock of popular Flight Simulator's in the marketplace.
1. Lockheed Martin Prepar3D check out here it's System requirements
. If you want to purchase a Licence check out here Prepar3d Store
2. Laminar Research X-Plane 11
3. IPACS Aerofly FS Flight Simulator
Both the Flight Simulator's X-Plane 11 and Aerofly FS Flight Simulator are available to purchase on the Steam gaming platform. If your not sure of what Steam is check out this link What is Steam
Steam is currently running their Northern Hemisphere Summer Sale.
You can purchase X-Plane 11 from now through until 10 July for NZ$ 52.79
Check your Laptop spec's with the X-Plane 11 Steam System spec's.
If you are only interested in wanting to fly in the Tecnams and Van's RV, then the Xplane.org has available to purchase these Tecnam P92
US$14.95 or the Tecnam P2002
They also have the Van's RV-8 /8A Duo
You can purchase currently Aerofly FS 2 Flight Simulator on Steam for NZ$ 49.49 until 10 July.
I believe that a Tecnam is available for Aerofly FS 2, but not sure about the Van's RV home build light aircraft for recreational flyers.
If you decide to go for Lockheed Martin Prepar3D or the now older outdated FSX then you could look at the Orbx Van's RV 4
In terms of purchasing a flight stick. A hands on throttle-and-stick HOTAS could be considered. You may liked to look at perhaps the Thrustmaster T16000M FCS HOTAS (Joystick & Throttle)
from PBTech or just the Thrustmaster T-16000M Joystick
on it's own from Mighty Ape.
It's best to have a look around to see whats going to fit with you and depending on how much your willing to spend these days, in setting yourself up to complement your real life RAANZ flying of the Tecnams and Van's RV.
I would also recommend checking out the SimHanger Flight Simulation Youtube channel Mark is very good at making some useful information videos, he has just recently done this one Flight Simulation In 2020 | Which Graphic Card is Right for You?
If your interested in getting into Virtual Reality VR Flying and wearing a Headset Mounted Display HMD ie; the vr goggles.
Mark from SimHanger Flight Simulation has also done a video HP REVERB G2 | Specifications now out | What you need to know
This VR HMD will be available later this year in New Zealand with the (estimated) release date 30th September, 2020. Price NZ$1099.00 on the Mighty Ape website being linked here HP VR 3000 Windows Mixed Reality 4K Reverb G2 HMD
As it stands both your Dell and HP Laptops are likely not VR ready, meaning it won't be able to run, VR supported program applications which require a VR Headset ie; the VR goggles.
The best way to confirm is for you to check out and do a SteamVR Performance Test
for Free and read the RoadtoVR article here How to Tell if your PC is VR Ready
. Or do a Windows Mixed Reality PC Check
Free app from the Microsoft Store.
Hope this goes someway in helping out, in the decision making process.
