Flyability

Category: Aviation

Flyability is the first proper Nexus Aero software product and provides simple long-range flyability planning for balloon pilots and aerial users.

Updated October 2026 · Version 2.0

What's new in Flyability 2.0

Flyability was our first product, and we haven't forgotten it. Version 2.0 is a full refresh, shaped by how pilots and crew actually use it at the launch field: the answer comes first, with the detail one tap away.

Next flight slot

Opens straight onto your next sunrise or evening slot, with a clear verdict and the best slot in the forecast.

14-day glance strip

Every morning and evening slot as ✓, ! or ✕. Tap a day to jump straight to it.

Hour by hour

See the hours either side of each slot, so you can judge whether waiting a little helps.

Compare your sites

Ranks your saved launch sites for any slot, best first. Tap one to switch to it.

Drift direction

Shows which way the balloon will drift, not just where the wind is coming from.

Send to crew

Share a short summary of any slot to WhatsApp or text in one tap.

Your units

Choose knots, mph, km/h or m/s. Your limits convert automatically.

Quick setup

The first time you open it, pick your launch site and personal limits and you're ready.
