When the radar of the F15E is displayed on the MFD, it can see the display altitude scanning altitude range to the right of the TDC. But this range is confusing to me, I don’t know if it’s my illusion but I feel like it’s too large. My radar is not searching such a vast area, and I often fail to spot threats that I face. For example, at the scan Angle in the figure, the radar covers an altitude of 44K FT to -17K FT at a distance of about 30nm, but my radar has difficulty finding more targets at this Angle.
I don’t know if anyone has tested this in detail.
I did some calculations and the actual scan height was only half the value on the MFD, so I had to calculate the center point to re-calculate the scan height.
