In a steady climb at a steady IAS, the TAS is

  • more than IAS.
  • the same as IAS.
  • less than IAS.

Explanation from PART66Online

As an aircraft climbs the air density falls, so for a constant indicated airspeed the true airspeed must be higher to produce the same dynamic pressure on the pitot system. True airspeed therefore exceeds indicated airspeed, the gap widening with altitude.

As u go higher the air becomes less dense so ias is always smaller than tas.
