# WEATHER LAYERS IN CLIMB AND GO-AROUND PROFILE VIEW Enable weather overlays when viewing your climb or go-around profile. You can now display winds aloft (as wind barbs), as well as temperature gradients, cloud layers, and likely areas of icing conditions, all alongside your climb and go-around profile based on performance calculations. # WORLDWIDE WEATHER AND WINDS ALOFT SF50 TOLD now uses worldwide weather data from Open-Meteo wherever USA NWS data is not available. Open-Meteo provides surface conditions as well as winds and temperatures aloft, both for current and forecast time periods. USA NWS data has been expanded to include Alaska and Hawaii. And as before, Apple’s WeatherKit is used for surface conditions when no other source of weather is available. Winds aloft within the US is interpolated from official reporting stations when the departure/arrival airport does not have its own winds aloft reporting. # BUG FIXES AND OTHER IMPROVEMENTS - Fixed a crash when loading nav data (caused by invalid airport surface data from the FAA). - More crash fixes related to full disk space. - Fixed a bug which would cause the airport search field to not disappear. - Improved nav data import speed.

- Fixed the app freezing for several seconds while installing new navigation data. - When the weather service is unavailable, the app now says so instead of reporting the download as corrupted. - Diagnostic reports no longer include your IP address.

Fixes crashes or hangs when updating navdata.

- Minimum iOS version now 26.0. - More Liquid Glass adoption. - Views now use Dynamic Type for better scaling at different screen sizes. - Weather data is now dowloaded at app launch rather than when an airport is first chosen. - Even more performance improvements, mostly thanks to new technologies introduced in iOS 26.

Fixes a critical magnetic variation bug

More bug fixes and performance improvements.

Minor bug fixes: - Fixed a launch freeze that could block the app for ~15 seconds on startup. - Improved overall responsiveness for some operations. - Now shows a clear error when terrain data can't be saved because the device is out of storage.

* More gracefully handles out-of-space errors when downloading terrain data. * Faster first-time launch.

Minor performance improvements to reduce instances of the app freezing or stuttering.

* Fixed a crasher when automatically downloading terrain after first installing. * Moved warnings from the main takeoff/landing page to the Operational Warnings page. * Improved error reporting.

This release focuses on better supporting part-135 operators with enhanced contaminated runway analysis, detailed distance breakdowns, and operational warnings aligned with FAA advisory circulars. RUNWAY CONDITION CODES (RwyCC) Select a Runway Condition Code (1–6) as a contamination type, and SF50 TOLD will apply the appropriate landing distance factors from AC 91-79B. Factors automatically adjust based on whether the runway surface is grooved/PFC or smooth. When RwyCC factors are applied, the configured safety factor is bypassed since the advisory circular factors already include built-in margin. VREF ADDITIVE Add a VREF additive speed on the landing page to account for gusts or other operational requirements. The additive is factored into landing distance calculations using the AC 91-79B §5.2.2 method, and is included in the TLR. ADJUSTMENT BREAKDOWN Takeoff and landing results now show a full breakdown of how each adjustment — wind, gradient, surface, contamination, safety factor — contributes to the final distance. See the base distance and each incremental change so you can understand exactly where your numbers come from. PERFORMANCE NOTES & WARNINGS Results now include contextual notes and warnings: distance exceedances, weight limit violations, crosswind/tailwind exceedances, insufficient climb gradient, and informational notes about supplemental data or approximations. OTHER CHANGES - Runways now track whether their surface is grooved, PFC, smooth paved, or turf, pulled automatically from FAA and OurAirports sources - New "Use AFM Safety Factors" button in Settings to quickly reset dry and wet safety factors to the AFM defaults - Safety factor field now accepts two decimal places for finer control - Fixed a crash that could occur when updating from a previous version - Improved stability of the home screen widget when app data is updating

CLIMB AND GO-AROUND PROFILES After computing takeoff or landing performance, you can now view a cross-section profile of the aircraft's climb path relative to terrain and obstacles. For takeoff, choose between runway heading, a vectored heading or track, or a published SID to see how the aircraft climbs along that route. For landing, view the go-around climb path along the published missed approach procedure or a vectored heading. The profile chart shows terrain elevation, obstacles, waypoints with altitude restrictions, and highlights any terrain conflicts along the route. Climb profile calculations incorporate winds aloft data. Obstacle and instrument procedure data is sourced from the FAA's Digital Obstacle File and Coded Instrument Flight Procedures and is currently available for US airports only. TAKEOFF/LANDING DISTANCE VISUALIZATION A new satellite map view shows the required takeoff or landing ground roll overlaid on the actual runway. A colored chevron pattern indicates whether the required distance fits within the available runway. For takeoff, blue means sufficient runway is available and red means insufficient. For landing, blue means sufficient runway is available from the touchdown zone, yellow means sufficient runway is available from the threshold, and red means insufficient runway is available. Any runway shortening due to NOTAMs is highlighted on the map. TERRAIN DATA The app can now download worldwide terrain elevation data for use with the climb and go-around profile views. Terrain regions can be downloaded and managed in Settings. A status indicator on profile views shows whether terrain, obstacle, and instrument procedure data are available and current for the selected airport. OTHER UPDATES - Runway shortening from NOTAMs can now specify whether the closure is at the departure end or the threshold - Enroute obstacle climb gradient and rate data added for normal and icing conditions across all aircraft generations BUG FIXES - Fixed app hangs caused by airport search sorting and nearest-airport queries running on the main thread - Fixed repeated database re-faults when displaying nearby airports after location updates

* Fixed a crash when using G2 regression data

Version 3.3.3 fixes a bug that would cause incorrect "offscale high" results on the Climb page. DOWNLOADED NOTAMS SF50 TOLD will now download live NOTAMs after you select an airport. You can view these NOTAMs by tapping the “NOTAMs” button on the takeoff and landing views. Use the downloaded NOTAMs to help you fill out the takeoff/landing shortening, obstacle, and contamination fields. G2/G2+ AFM UPDATES (REISSUE A) SF50 TOLD now has a "Wet Runway" contamination type, that adds 15% to runway distances for the G2/G2+. The G1 AFM has not been updated with the new Wet Runway data, so (for the tabular model), no correction will be provided. (A 15% correction will be applied if you use the regression model.)

Version 3.3.2 fixes a bug with G2+ performance data and limitations. DOWNLOADED NOTAMS SF50 TOLD will now download live NOTAMs after you select an airport. You can view these NOTAMs by tapping the “NOTAMs” button on the takeoff and landing views. Use the downloaded NOTAMs to help you fill out the takeoff/landing shortening, obstacle, and contamination fields. G2/G2+ AFM UPDATES (REISSUE A) SF50 TOLD now has a "Wet Runway" contamination type, that adds 15% to runway distances for the G2/G2+. The G1 AFM has not been updated with the new Wet Runway data, so (for the tabular model), no correction will be provided. (A 15% correction will be applied if you use the regression model.)

Version 3.3.1 fixes some G1 vs. G2 limitations (such as maximum altitude), displays climb speeds in Mach above FL180, and updates regression equations to improve accuracy. DOWNLOADED NOTAMS SF50 TOLD will now download live NOTAMs after you select an airport. You can view these NOTAMs by tapping the “NOTAMs” button on the takeoff and landing views. Use the downloaded NOTAMs to help you fill out the takeoff/landing shortening, obstacle, and contamination fields. G2/G2+ AFM UPDATES (REISSUE A) SF50 TOLD now has a "Wet Runway" contamination type, that adds 15% to runway distances for the G2/G2+. The G1 AFM has not been updated with the new Wet Runway data, so (for the tabular model), no correction will be provided. (A 15% correction will be applied if you use the regression model.)

DOWNLOADED NOTAMS SF50 TOLD will now download live NOTAMs after you select an airport. You can view these NOTAMs by tapping the “NOTAMs” button on the takeoff and landing views. Use the downloaded NOTAMs to help you fill out the takeoff/landing shortening, obstacle, and contamination fields. G2/G2+ AFM UPDATES (REISSUE A) SF50 TOLD now has a "Wet Runway" contamination type, that adds 15% to runway distances for the G2/G2+.

* Better handling of errors when loading weather (e.g., due to being offline): No longer displays a full-screen sheet, and shows user-entered weather info if given * Fixed crash that happened when attempting to load weather while offline * Fixed UI slowness when searching for an airport * Other minor changes

* Restored the ability to search for airports by city name. * Minor bug fixes.

EN ROUTE CLIMB VIEW Intended to be used during flight, this view shows you your best en route climb speed (95% best rate of climb) from the AFM. Use the sliders to set your fuel remaining, altitude, and outside air temperature, and adjust them periodically to ensure you continue to maintain your best rate of climb. Useful for when ATC requests your best rate, or just want you want those warm fuzzies that your Vision Jet is giving you its best. CUSTOM UNITS Set your desired units for everything: weight, volume, speed, air pressure, etc. Useful when flying in Europe or other metric areas. SEPARATE DRY/WET SAFETY FACTORS If your OpSpecs require you to use different safety factors for dry vs. contaminated runways, now you can give SF50 TOLD these two different safety factors. SF50 TOLD will use the "wet" safety factor for all contaminated runway landings.

NEW FEATURE: CUSTOM TAKEOFF/LANDING SCENARIOS Customize your Takeoff/Landing Report with your own scenarios. Under Settings, tap Takeoff/Landing Scenarios…, and then add or remove scenarios. Scenarios can include changes in weight, weather (wind and OAT), flap setting, or contamination (water/slush/snow/ice). RESTORED: TAKEOFF/LANDING NOTAMS Tap the “NOTAM” button to add NOTAM information to your takeoff/landing performance. For takeoff performance, you can add an obstacle height + distance, and you will be warned if your takeoff climb gradient is insufficient. For landing, you can add an obstacle (for go-around climb gradient) as well as runway contamination (rain, slush, snow, or ice). Contamination data is taken from the AFM Contaminated Landing tables, and is available in both the Regression and Tabular models. BUG FIXES AND IMPROVEMENTS * Landing total distance now increases with contamination NOTAMs (along with landing roll). An AFM notice is now displayed when using contamination data. * Offscale low/high warnings shown again when using regression model. * Improved responsiveness of airport search.

Version 3.0.2 fixes a bug causing incorrect density altitude calculations (display only). Version 3.0 adds numerous features including international airport data, a tabular data model, and takeoff and landing reports. INTERNATIONAL AIRPORT DATA SF50 TOLD now includes data for over 22,000 airports and airfields internationally through OurAirports.net. US airports will continue to use official FAA data, updated every 28 days. International airports will use open-source OurAirports data, updated regularly. TABULAR DATA MODEL Traditionally, SF50 TOLD used a regression data model for performance calculations, which allowed the application to provide performance estimations in all conditions, at the expense of some accuracy at the edges of the performance envelope. Now we are introducing a tabular data model that uses AFM tables directly, only performing linear interpolation within the envelope. You will be able to choose which data model you want to use. The tabular data model will produce book-accurate numbers for all conditions within the SF50’s envelope, but will not be able to extrapolate. The regression data model will provide performance data even in conditions not covered by the AFM, at the expense of some accuracy. TAKEOFF AND LANDING REPORTS A new “Generate Report” button has been added to the Takeoff and Landing sections. It will generate a PDF report of the predicted takeoff/landing performance for every runway at the departure/arrival airport, as well as limiting factor. It will also include hypothetical scenarios so you can see how potential changes can affect your ability to takeoff/land from each runway at your airport. These scenarios include a ±200 lb change in weight, a ±10° change in temperature, a ±10-knot change in winds, a flaps-50 landing, etc. The PDF report can be saved or printed. WORLDWIDE WEATHER SF50 TOLD now uses Apple Weather to provide worldwide weather conditions and forecasts. This weather data is used when NOAA METARs or TAFs are not available, as is the case for smaller US airports and all international airports. OTHER ADDITIONS AND IMPROVEMENTS - Regression data model redesigned to improve accuracy, especially at the edges of the envelope - When using regression data model, all performance values shown with an estimation range (e.g., “±200 ft”) - You can choose between showing all times as UTC or airport-local - Now calculates runway headings from runway end lat/lons for airports whose runway headings are not published - Re-released for iOS 26 - Bugs and data errors fixed
