If the density altitude is calculated to be about 2000 feet, what true airspeed would correspond to an indicated airspeed of 107 knots?

  • A

    107 kt

  • B

    108 kt

  • C

    110 kt

  • D

    113 kt

Refer to figure.
1. On the density altitude slide rule, set the marker to “2” to represent 2000 ft. Next, locate 107 kt on the inner scale.
2. Read across to the outer scale, where the corresponding true airspeed is shown as 110 kt.
