Aerogram - Flight Weather

Aerogram turns your route into a complete preflight weather briefing — built for pilots, fast to check at the gate and fully usable offline in the air.

GRAMET — route cross-section

Clouds, icing, freezing levels, the tropopause, turbulence and winds along your entire route in one vertical chart, with your cruise level overlaid. Pan, zoom or open it full screen.

Route & plan chart

A top-down view of the route with SIGMETs, alternates, a 2D turbulence/convection field and a satellite layer.

Destination & alternates

• MOSMIX hourly cards and meteogram centered on your landing time

• METAR and TAF with the period that covers your operation highlighted

• Estimated ceiling, flight category (VFR/MVFR/IFR/LIFR) and probable runway by wind

• NOTAMs with aerodrome/runway closure flags around your ETA

Smart route analysis

• SIGMETs that intersect your corridor

• Turbulence (EDR) warnings by phase and time of flight

• Wind/level trade: the best cruise level for the winds, with save/penalty vs your current FL

• Live GPS position plotted on the charts

AI briefing

An optional plain-language summary of the whole study.

Offline & PDF

Every study is saved for offline consultation in flight and can be exported as a full, multi-page PDF to share or file.

Free to use, with an optional Pro subscription for unlimited studies and AI briefings.
