NAV RADAR / TAWS on HDD 1/4

[NoPro]

During the training missions, all is as expected but when I do a selfmade mission, I can’t get the NAV RADAR on HDD1 and the TAWS on HDD4. HDD2 and 3 are working respectively. So what I’m doing wrong?

Did you not bring up the HUD?

If your HUD is stowed, the plane won't allow you to take the PFD off of HDD 1/4. Lower the HUD and you'll be able to change the page.
