Set autopilot to fly approach -> activate ILS. Besides the radio there’s essentially no other controls you would need to touch in an emergency (landing gear (if not handled by ILS), autobrake, engine stop, parking brake, door controls), and it’s very easy (by design) for the tower to talk you through the settings to do that. This meme is more than enough to familiarize you with the basic control locations in case you need to make an adjustment based off tower instructions, but at the same time buddy chill TF out it’s a meme.

(note that realistically it would never be you-a-passenger doing this, it’d be one of the cabin crew)
