What is boost? And how to use/monitor it?

[Peril]

As a side to this topic, RAM air also boosts the altitude at with you can maintain max boost levels. On average this seems to be around an extra 3000ft at full speed. This is noticeable in the difference in max hp achieved in static condition tests vs max speeds tests which have the advantage of RAM increasing the max alt/hp. As you slow up this assistance is reduced making RAM effect less influential to the boost maintainable under climb speeds.

If that makes sense.
