    So you need Bernoulli's equation to solve this.
    Inside the cabin you are at STP - so you know P1 and the specific gravity of air at STP...
    I suggest that you assume p2 is zero (high altitude). That ...

    Solution Summary

    Bernoulli's equation is applied. The cabin pressure applied in an airplane flying at high altitude are given.
