	Another option for calculating TLI parameters involves ~~use of~~ the '''Transfer MFD''' (included in the base Orbiter installation). This method involves calculating the burn parameters (delta velocity and time until burn) within the MFD, then inputting the values into the AGC or the [[ProjectApolloMFD\|Project Apollo MFD]] TLI burn program. It is simpler to use than the IMFD method, albeit less precise.		Another option for calculating TLI parameters involves using the '''Transfer MFD''' (included in the base Orbiter installation).
