Usage of the Future

One uses the future tense when referring to an action, certain to occur, in the future. In a time ahead of now.

One may also use aller in the present tense in conjunction with aller or another verb in infinitive form, to refer to the future. However it is not the future tense.

For example,

Il va aller à l'école

Or

Je vais dormir

Holds generally the same meaning as,

Il ira à l'école

Or

Je dormirai

However, the former is not in the future tense. Also, the usage of "aller" generally signifies an action to occur in the very near future, where as future tense refers to any time in the future.
