+
+#### Caveats
+- GSX acts as a visual indicator, the actual fueling is managed by the aircraft's own systems. This allows you the freedom of [various fueling times](#realism-settings-for-fuel-time).
+
+#### Usage
+1. Fueling
+      - The "play" button is disabled until the fuel truck has arrived and the hose is connected
+      - Select `Request Fueling` from the GSX Menu
+      - Wait for the fuel truck to arrive and connect the fuel hose.
+      - Set the [fuel quantity](#fuel-and-de-fuel) that you desire and press the "play" button.
+      - You can witness outside as the fuel truck begins to re-fuel your aircraft
+2. De-fueling
+     - Due to limitations with GSX, this is not supported, disable [Fuel Sync](settings.md#3rd-party-options) temporarily, to defuel.

+!!! danger ""

+!!! warning ""
+    You must enable [Payload Sync](settings.md#3rd-party-options) in order for this to function.
+
+#### Caveats
+- You won't witness passengers boarding the aircraft until physical passengers from GSX enter the aircraft. You'll notice this when you request boarding through the GSX menu but nothing appears to happen in the EFB just yet.
+- Due to limitations with events emitted by GSX, cargo/baggage loading is less granular and the aircraft own's weight systems will load in large chunks rather than much more fine grained steps.
+- The aircraft's own boarding sounds are disabled as GSX has it's own sound profile for boarding/deboarding.
+- Once boarding has started you can no longer, edit the fields in the payload screen
+
+#### Usage
+1. Boarding
+      - Load the aircraft as per normal following the instructions defined in, [Setting Up Payload](#setting-up-payload).
+      - Before proceeding, ensure you've set *everything*  to your preferences, this is a point of no return. 
+      - Select `Request Boarding` from the GSX Menu.
+      - The payload page will now enter a disabled state, where you can no longer modify anything until *after* deboarding has completed.
+      - Continue with your pre-flight setup and/or observe on the payload page as the aircraft is boarded with passengers and cargo.
+
+2. Deboarding
+      - Once you've arrived at the gate, as per normal, Select `Request De-Boarding` from the GSX Menu.
+      - Observe on the payload page the aircraft is deboarded and cargo removed.
+      - Once the deboarding is complete, the payload page should once again become editable.

+    The aircraft comes with a GSX profile, this requires no extra action from yourself. However, it is worth mentioning due to modelling constraints, the aft cargo and passenger door have been disabled, as these cannot be opened.
