True or False: At altitudes near sea level, the difference between an aircraft's true and indicated airspeeds is negligible.

The statement is true because at altitudes near sea level, the effects of atmospheric pressure and temperature on air density are minimal, resulting in a close correlation between true airspeed and indicated airspeed. Both types of airspeed are measured in similar environmental conditions, making the discrepancy between them quite small, which is particularly true for aircraft operating at lower altitudes.

As altitude increases, the significant variances in air pressure and density begin to affect the readings, leading to greater differences between true and indicated airspeeds. However, at or near sea level, these differences are negligible, allowing pilots to confidently use indicated airspeed for their operational needs without substantial correction for true airspeed.
