Just like adding flights manually, Wingman has the feature to add the Simulator entries in the app.
Please follow the given procedure.
How to add simulator entry on the Wingman app?
➤ Open the Wingman app and click on the 'My Flights' page.
➤ Press the '+' icon and click the 'Simulator' option.
➤ Fill all the mandatory fields (marked with red asterisk) and other fields about the Simulator session.
➤ Click 'Save' and your Simulator entry is added digitally to your Wingman profile.

The simulator entries cannot be uploaded to your eGCA profile as it requires multiple documents to be uploaded for each simulator entry.
You can refer the article below to upload Simulator entries to eGCA.

The simulator entries are added to the Wingman profile for your own reference and to keep a record of it digitally.
