Heads-up, hands-free: How to use iPad audio alerts for safer flights

iPad Pilot News

IN-FLIGHT ALERTS 500 AGL Alerts – Alerts when descending through 500 ft. AGL after having been above 1,000 ft. The alert will only sound once every 60 seconds and is automatically disabled if groundspeed is less than 40 knots. AGL (or when AGL is unknown), the descent rate exceeds 4,000 ft. per minute.

Descent Planning: Strategies for Safe and Smooth Arrivals

Flight Training Central

As an example, the Garmin GTN series offers a vertical calculation (VCALC) function that includes the ability to set a desired rate of descent to calculate the appropriate point to begin your descent based on your aircrafts current groundspeed. You can also view your TOD from the flight plan profile view on the Maps tab.

Riding the Mountain Waves

Plane and Pilot

FAA weather charts can help for higher altitudes but when just a few thousand feet agl, they may be less useful. Using my 80-knot tailwind and a stationary wave, my groundspeed and therefore penetration speed through the wave would be 160 knots faster than an upwind approach and theoretically more turbulent. We didn’t test it.

FAA Updates Datalink Weather Advisory Circular

iPad Pilot News

Pilots that are comfortable with self-briefing, via FAA Flight Services, or an equivalent means, may use the EFB to display the METI and AI as well as to file flight plans. For example, ground-based systems that require a line of sight may have relatively limited coverage below 5,000 feet above ground level (AGL).
