Negative radio altimeter after SP1

[Habejom 0]

Hello everyone.Does anyone have experienced this, or knows how to solve it? After SP1, when on ground, my RADIO altimeter shows -4. As I understand it, it should read 0, never a negative number.Any thoughts?Regards,Armando Arjona R.

I have the same thing.

As I understand it, this is a valid reading. The RA is calibrated to show precisely 0 on touchdown in the flare attitude. Once the nose comes down the reading is -4.

This is normal... and very realistic. The above comment is correct. 747-400's have a negative RA value annunciated when on the ground aswell.Ashley Frew.

Hmm, that's very interesting...

Yes, this negative value is correct and new to SP1.Well done PMDG for adding even more realism.Fred.
