airspeed value.
13. Increase the airspeed to the upper red radial/top of yellow arc (Vne).
14. Verify that the red radial on the standby ASI and PFD airspeed tape are at the same airspeed value.
15. Starting at the current airspeed, decrease the airspeed to zero, stopping at each of the airspeeds
listed in Table 5-3 (airspeeds above Vne should not be checked), verifying that the PFD and
standby ASI airspeed values are within the tolerances indicated in Table 5-3.
