SimBrief integration: link your account once and load the latest flight plan with one click. Fills in aircraft type, TOW, runway, weather and W&B data automatically.
Flight info strip: when a SimBrief plan is loaded, a strip above the form shows flight number, callsign, aircraft type, origin/destination, times (EOBT, ETOT, ETA, EIBT, block/flight time), cruise level, SID/STAR and route. The strip stays visible after pressing Calculate.
Runway from the SimBrief flight plan is automatically pre-selected in the dropdown.
VRB wind: variable wind direction is resolved to the midpoint automatically. A variation range (e.g. 280V350) is noted as an advisory.
W&B (Weight & Balance) calculator: enter passengers, cargo and fuel to estimate the CG with an interactive aircraft silhouette overlay. The result is applied to the takeoff form in one click.
SimBrief pre-fills the W&B calculator using a forward-biased distribution (passengers front-to-back, cargo 60 % forward) for a realistic initial CG.
Cargo hold split slider: drag to redistribute cargo between FWD and AFT hold while keeping the total constant.
CG estimate notice: a warning appears under the CG field when the value was calculated from SimBrief data, with a direct link to open the W&B calculator for manual adjustment.
CG envelope limits corrected for all types: A319 and A321 to 41 % MAC, A320, A320neo and A330 to 40 % MAC.
Version 2.0
New design, new start page and a landing-performance placeholder (in development).
Optional free accounts (registration and sign-in). The takeoff calculator still works without one.
METAR retrieval moved to the current aviationweather.gov data API (the old data server has been discontinued).
Runway condition from the METAR is now only set to Wet for precipitation, not for mist or fog.
Runway data and METAR are loaded through new, hardened endpoints; unknown airports are counted for later addition.
Gross weight entered in lbs is now kept in the form after calculating.
Corrected several runway records in the airport database.
Version 1.5
Automatic download of METAR information for major airports.
Integrated data-picker for airport information (runway designator, heading, length, elevation). Used ICAO codes are stored to prioritise the database updates.
Version 1.4
Revised Flex Temp calculation for longer runways (limiting value error removed).
Version 1.3
Anti-Ice correction for A319/A320/A321 adjusted.
Air-Conditioning correction error for A319/A320/A321/A330 resolved.
Internal ISA+53 and ISA+40 calculation (limiting Flex max) adjusted (metric vs. imperial system).
Version 1.2
Entries are stored and copied even if some of the entered values are wrong or out of range.
TOCG (not ZFWCG) for T/O trim calculation required. Entries for CG are automatically increased/decreased to min./max. T/O CG values.
New avail. A/C types: A319-132, A321-211.
Version 1.1
Entries are stored and copied even if some of the entered values are wrong or out of range.
