Citation I/SP (Model 501) TOLD Calculator

Not an operational or dispatch tool. This calculator reproduces takeoff and landing tables exactly as printed in the uploaded Pilots' Abbreviated Checklist (Model 501 Citation I/SP, Rev. 28). It performs only linear interpolation strictly within the printed weight / pressure-altitude / temperature grids — it never extrapolates beyond a table's printed range, and it flags any input that falls outside the source data instead of guessing. The source charts assume a dry, paved, level runway with zero wind and provide no correction factors for wind, runway slope, or contaminated surfaces — so none are applied here. This abbreviated checklist also does not contain accelerate-stop/accelerate-go, balanced-field, or obstacle-clearance climb-gradient charts, so those are not available in this tool. Always verify against the current, complete AFM/POH and company procedures before any real flight.

Aircraft Configuration

Configuration (determines which table set applies)

Per the checklist's Configuration Codes table (Temporary Change, p.iv–v). If you're not sure which applies to your airframe (early serials depend on Service Bulletin incorporation), check your aircraft's checklist page footers — they print "Configuration AB" or "Configuration AC" directly.

Takeoff Conditions

Takeoff weight (lb) Field elevation (ft) Altimeter setting (inHg)

Pressure altitude computed as elevation + (29.92 − altimeter) × 1000 (standard formula, not aircraft-specific data).

OAT (°C) Anti-ice

OFF ON

Runway length available (ft) Runway surface Wind component

Runway gradient (%)

Landing Conditions

Landing weight (lb) Field elevation (ft) Altimeter setting (inHg) OAT (°C) Runway length available (ft) Runway surface Wind component

Results

Select a Configuration, fill in takeoff or landing conditions, and press Calculate. Results appear here with the exact source page/table used for every number.

Data source: Rudy's uploaded Model 501 Citation I/SP Pilots' Abbreviated Checklist, Revision 28 (501CL-28), Normal Procedures section, pages N-8 through N-23.1 (including the N-8/N-8.1, N-11/N-11.1, and N-13/N-13.1 thrust setting tables). All takeoff and landing distance figures are reproduced or linearly interpolated from the printed tables; no data has been invented, extrapolated beyond a table's edge, or sourced from outside this document. Anti-ice, wind, slope and dispatch factoring are applied only where the source itself provides a factor (anti-ice ON ×1.25 on takeoff distance); wind/slope/contaminated-runway corrections are not published in this document and are therefore not computed.
