Caption: X-IFU simulated observation lasting only ~120 seconds of the Black Hole binary GRS1915+105. A disk wind, as reported by Miller et al. (2016) has been simulated. Strong spectral features can be clearly seen in the spectrum, including Fe XXV K? (6.65-6.75 keV), the resolved doublet Fe XXVI K? (6.95 − 7.00 keV), Fe XXVI K? shifted by 0.01c (7.00-7.05 keV), Fe XXVI K? shifted by 0.03c, Fe XXV K? (7.65-7.90 keV) and Fe XXVI K? (8.20- 8.35 keV). This rich set of features will enable unprecedented studies of the structure of the disk winds.

Additional comments: The exposure time has been upscaled by 20% to account for the effective area of the response matrices, considered as the baseline for the X-IFU Instrument Preliminary Requirement Review.
