In multiplayer and in default test flight, there is a long list of settings for you. however this is not always the case in singleplayer, mission editor and dynamic campaign
Context for mission editor:
Not many people know this, but the test flight can be edited(thanks to https://www.youtube.com/watch?v=aProhkw7eZQ 1:53 for teaching me this) by clicking mission editor at the bottom left in test flight; however this is only avaliable for aircraft in your lineup and only for planes, and the map choices are limited.
In mission editor, dynamic campaign and singleplayer, the settings are extremely limited to what i speculate is the old war thunder mission settings;

Singleplayer and dynamic campaign:
Most of the time, this is not a big deal, except for the fact that we cannot set bomb fuses and set the fuel amount. this makes singleplayer nearly immposible in realistic and simulator for missions like blind operation and paulaus’s last tanks and dynamic campaign.
Additionally, i hope that gaijin makes it possible to do mission editor in tanks and ships and also provide more maps in mission editor.
