Need to find the True Air Speed

  1. Sep 14, 2011 #1
    1. The problem statement, all variables and given/known data
    An aircraft has IAS 200 knot at pressure altitude 25 kft. Change in Vp is +1 knot. If standard day, find the TAS.


    2. Relevant equations



    3. The attempt at a solution

    Don't know how to do this.

    We probably need more info to be of any help. Can you define the problem more completely? What is meant by "Change in Vp is +1 knot."? I assume that IAS = indicated air speed, and TAS is true air speed?

    What does being at 25000 feet elevation do to change IAS so it does not match TAS?
