737ng RA

[Jedi 737]

Hi everyone. Simple question. Why does 737ng RA show -4 altitude on ground.is it a compensation for Angle of attack during approach?

It should read 0 with aircraft in its landing attitude with struts compressed, so -4 with all wheels on the ground is normal.

[de facto]

yes…calibration of the RA as said above.
