Well...
It has two (2) selectable views, ...each has a different angle/approach speed and bombsight.
You can also select/de-select the gauge panel if you need the wider view.
The 200 mph approach speed view is the low-level bombsight/look-ahead view with a 39.45 degree depression angle. (for 5,000 feet and under or look-ahead)
The 155 mph approach speed view is the high-level bombsight/look-down view with a 57.50 degree depression angle. (for 5 to 25,000 feet)
Make sure the zoom is set to 1.00, ...the autopilot takes care of the elevation and wing-leveler once set, ...set the rudder trim a few clicks to true the flightpath, ...steer with the rudder to line up the sight, ...manage your speed precisely and wait for the correct elevation hash-mark to cross the target.
Simple.
