Private Beta
LZCheck reads winds aloft, rotor risk, airspace, TFRs, and terrain for your exact LZ, then gives you one clear answer. Built for paramotor pilots, by a paramotor pilot.

The problem
Every flyable morning starts the same way: six tabs, three apps, one gut call. You cross-check sources that disagree, mentally interpolate a METAR from an airport 14 miles away to your field, and guess which model to trust today. That is forecasting work. You are a pilot, not a forecaster. And half of those apps charge their own subscription for a slice of the picture.
Sources that disagree are reconciled for you. Conflicts are shown, weighted, and resolved into one verdict with the reasoning attached.
Forecasts are computed for your exact LZ coordinates and elevation, not the nearest airport. The distance guesswork is gone.
HRRR, GFS, and bias-corrected consensus are blended automatically. You never pick a model or wonder if the other one was right.
What it does
One instrument, not another social feed. Every layer exists to answer go or no-go.
Live particle wind animation at nine altitude levels. See what the air is doing above your wing, not just at the surface.
SFC TO 12,000 FTMechanical turbulence flagged from real terrain data and wind direction. Know which side of the ridge bites today.
USGS 3DEP TERRAINControlled airspace, MOAs with live status, and temporary flight restrictions checked against your LZ automatically.
FAA SWIM FEEDModel bias correction pools anonymous pilot observations, so the forecast at your site gets sharper the more pilots fly it.
HRRR · GFS · MOSTwo sites, one screen, stacked forecast graphs. Pick the launch that wins this weekend, not the one closest to home.
MULTI-SITE VIEWDrop a pin on any spot on the map and get a full forecast for those exact coordinates. Scout new sites before they earn a saved LZ.

Other apps are weather viewers: they show you data and leave the interpretation to you. LZCheck is a decision instrument: it fuses wind, rotor, airspace, TFRs, and terrain for one specific LZ and outputs a verdict with its reasoning. You stop interpreting six sources and start checking one.
Many pilots pay for two or three overlapping weather services and still cross-check between them. Once you start using LZCheck, you may find you no longer need to pay double or triple just to check conditions before you drive to the LZ.
Ask your instructor for an access code. Sign up, enter the code, and you skip the wave queue - partner-school pilots get access right away.
Invites go out in waves as capacity and stability allow. Waitlist position and pilot activity determine order. Joining the waitlist is the only way in right now.
Forecast data is global by design. US-specific layers like terrain detail, airspace, and TFRs are deepest today, with more regions coming as data sources come online.
No. LZCheck is a web app that installs to your home screen and works offline for saved data. iPhone, Android, desktop, one account, always in sync.
No. LZCheck is a planning aid. It compresses the data you should be checking anyway, but the final call is always yours: current conditions, your skill, your equipment, your eyes on the windsock.
