Only the Rudder Axis has separate assignment options (Left/Right), while the Aileron Axis only has a single entry. If I map the controller triggers directly, I can only control one direction. If I set them as digital inputs, there is a default input delay and I lose the linear control effect. 
I am not understanding.
Are you using the joystick twist (default behavior) for rudders? Ailerons should follow the joystick axis as you push it left and right
I donāt understand what youāre trying to say. Also, from your title post -nothing is analog when you have a controller. It is all digital inputs. So please explain a little bit more so someone can help.

Since you reference ācontroller triggersā - youāre using an XBox Controller on PC?
It makes more sense to map pitch (elevator) and roll (ailerons) to one of the control sticks to emulate a joystick aircraft control scheme. It would also work better since both axes of the stick would have linear inputs. The triggers would only have an on/off input.
In DCS World, the Xbox controllerās LT and RT are automatically recognized as a single, combined Z-axis. However, in MSFS, they are treated as two separate axes. Since the Aileron Axis only accepts a single input, mapping a trigger directly allows me to control only one direction (50% of the total travel). Assigning them as digital buttons is not a solution due to the inherent input lag and the total loss of linearity/precision.
Iām trying to set up my Xbox triggers for Aileron control in MSFS, similar to how it works in DCS. In DCS, LT/RT function as a unified Z-axis, but MSFS treats them as separate inputs. This means I can only bank in one direction if I map them as axes. Setting them as buttons results in noticeable input delay and zero linearity. Is there a way to āmergeā these two triggers into one Aileron axis in MSFS?
Not in MSFS.
You can maybe use the Steam re-map controller functionality, but otherwise: no
