[... simple future ... if / when ... simple present ...]
Notice that there is no future in the if- or when-clause.
USE
The future real conditional (also called conditional 1) describes what you think you will do in a specific situation in the future. It is different from other real conditional forms because, unlike the present or the past, you do not know what will happen in the future. Although this form is called "real", you are usually imagining or guessing about the future. It is called "real" because it is still possible that the action might occur in the future. Carefully study the following examples and compare them to the future unreal conditional examples further down the page.
Examples:
If I go to my friend's house for dinner tonight, I will take a bottle of wine or some flowers. I am still not sure if I will go to his house or not.
