Citation I/SP (Cessna Model 501) — TOLD Calculator

Built from Rudy's Pilots' Abbreviated Checklist (501CL-28) — reference / training tool only. Not for flight dispatch.

v1.1.0
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

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.

Airport (optional)

Fills field elevation, altimeter, and OAT on both tabs from the latest METAR, and reports the observed wind for you to convert to a head/tail component. Advisory only — always confirm against your own altimeter and current ATIS before use. Requires a network connection; every field stays editable by hand. A 4-letter ICAO code is unambiguous; some 3-letter codes match more than one airport, and those fill nothing until you narrow them down.

Takeoff Conditions

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

Landing Conditions

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.
