Negative DH Rad Alt display.

[BoeingBoy]

As a current 757/767 Captain with a lot of 737 experience, I was recently discussing the fact that some Boeing installations allow the display of negative decision heights on the rad alt, with the reset switch setting the value back to a display of 0. This would seem to be the case in Qantas and the Pacific.

Conversly every installation I have flown on all three types in Europe does not allow the display of negative DH's and the reset switch just resets the colour of the DH.

Can I ask for a straw poll on how many of us have aircraft in either config as the argument centred on what is the default setting as supplied by Boeing and which is the company mod. We also wondered which is the more common.

Thanks.
