The more I use CloudAhoy, a free IOS app for iPhones and iPads, the more impressed I am.
This app is a great tool for debriefing flights with your safety pilot or instrument instructor to show exactly how well you tracked an airway or executed the instrument and missed approaches.
In the debrief mode, your actual route can be overlaid on Google Earth, a VFR Sectional, an IFR en-route or various published instrument procedures. It is amazingly accurate. The view can be tilted, or put onto 3-D mode, and viewed in north or track up. There is also a demo mode to replay the flight.
On a long cross country you can share your flight with friends or family with a simple email link.
I also use the app for log book purposes, which in my case is a customized excel spreadsheet. It tracks times for each segment of the flight, including airborne and taxi segments.
Here is how the flight segments look. In this case, we flew a total of 220nm in 2 hours and 4 minutes, including taxi times:
To track a flight, simply start the app while on the run-up ramp. It runs in the background using the GPS chip in your iPhone or iPad. CloudAhoy automatically shuts itself off when you land, and sends the telemetry data to the CloudAhoy server once a wi-fi or xG internet connection is re-established.
Below is a series of instrument approaches I flew with a CFII, overlaid on a sectional. We started out from Leesburg, FL, LEE, heading northwest then flew the GPS/RNAV 5 at Williston, X60. After the approach, heading southeast we flew ILS 36 at Ocala, OCF, then full approach to the GPS/RNAV 13 back at Leesburg. On the miss, we continued southeast to the ILS 7 at Orlando, ORL, and finally back to the northwest into Leesburg.
