Mercator and Lambert projections are commonly used by (Ship) navigators and aircraft pilots and navigators, supplemented by GPs and other electronic aids. the Lambert system produces a compact circular (sectional) chart easily slipped into instrument housings like bomb sights, drift meters, etc, it is graduated in azimuth, hence making targeting of landmarks easy. in soe models the operators make adustemnts to keep the target destination in the center of the cross hairs- this is on a map, not the actual ground. the projection is as similar as possible so when the Bombardier takes the sights- the image will be familiar i just know that much about this topic
I hope it helped you :-)
