Terrain and AGL

In the latest version of CloudAhoy you can see the terrain and the aircraft’s altitude AGL (Above Ground Level).

Terrain and AGL are shown in the Flight Graphs and Segment Info views which display altitude. AGL data is also used for scoring maneuvers in which the AGL is important.
* This feature is available in CloudAhoy Standard and in CloudAhoy Pro.

A picture is worth a thousand words – here are a few examples as some members of CloudAhoy team relive their past flights.  

Over the Grand Canyon

  • Aircraft: SR22
  • Flight data:  CloudAhoy App 
  • Pilot: Chuck Shavit. Flown in Mike’s plane (with Mike in the right seat)

“Memorable flight over the Grand Canyon, as a guest of a long-time user.”

Engine failure over the mountains 

  • Aircraft: C182
  • Flight data:  Foreflight with Stratus
  • Pilot: Kate Matteson

“I lost my C182 engine shortly after departure from KLEB in New Hampshire while flying solo. All the training in the world doesn’t prepare you for a real, single pilot engine out experience over mountainous terrain! The green line on CloudAhoy’s ALT/IAS graph shows I descended to 759 AGL before successfully restarting my engine, returning to the airport, and safely landing on RWY 36. Whew! Having the terrain/AGL makes the debrief extra meaningful.”

Crossing the Alps

  • Aircraft: DA42
  • Flight data:  G1000
  • Pilot: Markus Rex

Notice the IAS graph (blue): it becomes unstable as Markus crosses the alps (the brown graph). Mountain waves cause turbulence and significant variations in airspeed. At the time shown, the headwind was 68 knots.  Insightful to see the correlation between fluctuation of IAS and the peaks of the mountains! 

Over Grand Canyon in a simulator

  • Aircraft: SR22 (in a simulator)
  • Flight data:  X-Plane
  • Pilot: Seth Richards

“After developing the display of terrain in graphs, I wanted a cool flight I could use to demo the feature to the CloudAhoy Team.  I fired up X-Plane and flew an SR22 from KGCN across the Grand Canyon and back.”

Traffic Pattern

  • Aircraft: C182
  • Flight data: G1000
  • Pilot: Chuck Shavit

“I was practicing traffic patterns at KORH. The approach to RWY 29 is always fun because the runway is on top of a hill and the valley before it makes the approach feel steeper than it actually is.”

Landing with dad

  • Aircraft: C182
  • Flight data:  Foreflight with Stratus
  • Pilot: Kate Matteson

“Took my Dad for a sightseeing flight last Spring and was happy to have a really nice landing 🙂 “ 

Flying in Arizona

  • Aircraft: Beechcraft Sundowner
  • Flight data: ForeFlight with Stratus
  • Pilot: Chris Hufford

“How close was I to that mountain peak? 1386 AGL. From Marana, AZ to Safford, AZ for lunch.”
