Altitud display on Radar Screen

[TangoAir]

Hi,

the newer altimeters send coded signals in increments of 50 or 100 feet, to be seen on ATC Radar's?

thanks again,

100 feet on all the radars I've seen.

Hi Tango Air,

I understand that mode S transponders will be able to send altitude readouts to the nearest 25 feet. Still 100 feet increments displayed on our radars at the moment.

Thanks ATCO Two,

probably to be used by new TCAS and not for ATC radar display!

On RVSM, 25 vs. 100 make's a difference!
