How it works
The distance counts down from your groundspeed. If it drifts from the FMS, tap To fix and type the right distance. GPS altitude is satellite height, not your altimeter, and can be off a few hundred feet; switch Altitude to Manual to use the altimeter. Reference only.
Engine-out 2nd segment climb gradient from AFM Fig 4-31/4-32 at V2, gear up, read at airport + 1,500 ft, same as the takeoff climb limit. Uses the Takeoff tab's weight, flaps, pressure altitude, temp, wind and anti-ice.
Use the published VDP when the chart has one. This works it out from the height above touchdown at the glidepath angle you pick.

About this data
AFM data: Model 560 FAA-approved AFM 56FMA, Revision 11, serials 560-0260 thru -0538. Linear interpolation of the AFM tables, the same way you would do it by hand: between weights, pressure altitudes, temperatures and wind columns. Speeds are rounded to the nearest knot (VREF/VAPP rounded up); distances are rounded up to the next 10 ft. Wet and contaminated runway numbers come from AFM Section VII advisory information. Tailwind is limited to 10 kt; headwind above 30 kt uses the 30 kt column. This is a reference tool built from the AFM, not an approved performance program. Confirm against the AFM before flight. Airport and runway data come from OurAirports; declared distances (TORA/ASDA/LDA) and NOTAMs are not included, so check the Chart Supplement.
