Homework Help: Convert the EAS to TAS

  1. Dec 12, 2008 #1
    1. The problem statement, all variables and given/known data

    Hi, im realy stuck on this problem, i've been finding equations to convert the EAS to TAS but none of them have temperature involved.

    2) A Boeing 747 is cruising at an altitude of 10,000m the pilot looks at the air speed indicator (calibrated for ISA) which shows an EAS of 450 knts. If the sea level pressure is 101530 Pa and the temperature is 20 oC, calculate the True Air Speed (TAS) of the aircraft.

    2. Relevant equations

    the equation i've found is

    EAS = TAS * sqrt(actual air density / standard air density)

    3. The attempt at a solution

    the values i've got dont fit into the equation ???
