Hi,
1) on the Learjet45, we have the possibility to select the absolute mode for surrounding traffics, but the default mode is "relative"...It means that the system returns automatically to "rel..alt values" after 20" when abslo.. has been selected..
2) Usually the tcas display is allocated to the efis n°3 (= mfd /copilot) but can be transfered to the n°2 (mfd/captain)..
No way to invite the picture on a PFD...
Should a RA wakes up the crew..
a red and green arc will be displayed on both pfd
hopes this enrich your request a little bit.
merry Xmas..
