Airspace alerts
Arriving in 1.9.6Know about the boundary before you cross it.
Airspace alerts, arriving in Ascent 1.9.6 and on by default, project your track forward and warn you 5 and 2 minutes before you would enter active TFRs, the Washington DC SFRA and FRZ, prohibited and restricted areas, or Class B, C and D airspace. The check runs on the device against your installed offline packs, so it works without a connection. A spoken alert is optional. It is deterministic geometry, not AI.

What it does

A heads-up at 5 minutes and a warning at 2, from your projected track.
The airspace that bites
Active TFRs, the DC SFRA and FRZ, prohibited and restricted areas, and Class B, C and D.
Runs on the iPad
Checked against your installed offline packs, so it keeps working with no signal.
Optional voice
Hear the alert instead of watching for it.
Simulator aware
Alerts stay off for simulator sessions unless you opt in.
What it does not do
Know the limits before you rely on it.
- It needs current offline packs installed for the area you fly.
- It is a supplemental aid. Clearances, NOTAMs and the chart remain your responsibility.
- It does not alert for terrain or fuel.
