Approach Speed Calculator Pro vs xWind

Good morning, Captain. Join over 6,000 pilots who use this tool to brief the approach speed for every landing, even in gusty, challenging conditions. Set the runway and the wind with one finger on the compass, set your VREF, and the approach speed is there. No mental math, no typing. BUILT ON THE BOEING METHOD The wind additive follows the Boeing Flight Crew Training Manual (FCTM): half of the steady headwind component plus the full gust increment, never less than VREF + 5 and never more than the limit you choose, VREF + 15 or VREF + 20. With a tailwind only VREF + 5 applies. It applies from the 727 to the 787, and the same method is in use on Airbus and other jets. WHAT YOU SEE • Approach speed, with the additive shown as VREF + n • Headwind or tailwind component and crosswind component, each with its gust • Colors that speak: green inside normal values, yellow for caution, red beyond limits • A warning when the approach speed gets close to your full flaps limit speed • Descent rate for a 3 degree path • Ground speed on final • Reference stall speed MADE FOR THE FLIGHT DECK • A compass you drag: outer ring for the wind, center for the runway. Fine tune degree by degree with the buttons • Dark instrument display, easy to read by day and by night • iPhone and iPad, with landscape on iPad • Knots and feet per minute, or meters per second • Works offline. No account, no ads, no subscription For reference only. This app does not replace your aircraft manuals or your company procedures.

xWind is an easy to use tool to assist pilots in evaluating wind conditions with respect to head, cross and tailwind limitations. Once setup, the xWind app provides all information in one single screen, requiring minimal user interaction during high workload phases of flight, displaying: - Current wind direction and speed - Runway course - Cross and head or tailwind components - Currently applied wind limits - 'Forbidden' wind angles based on the current wind speed - Maximum wind speed table based on current wind limits ​ Reference wind, runway course, as well as wind limits, can all be adjusted on the main screen by either dragging the wind arrow, course rose or wind limit lines. A settings button at the bottom presents a popup screen where both the units for wind speed (Kts or Mps) and the default values for wind limits can be specified. In addition to the general setting for wind speed units, the user can select the alternative units for only the current wind, wind components and maximum winds table by double tapping the wind display at the top of the main screen. When operating from a Kts country into Mps territory, this option allows to set the current wind and see the maximum allowed winds in Mps, based on limits that are still set in Kts. Or vice versa.... xWinds supports iOS darkmode.
