Version 4 of ForeFlight Mobile HD is available for download from the Apple iTunes store.
According to a company representative, the new version focuses on six key features: airspace and airport/facility directory (A/FD) data, instrument approach plate organization and productivity, map interaction, improvements in the navigation log, personal waypoints, and performance.
The most noticeable additions are the A/FD data and chart legend information (special-use airspace, and so on) to the airport pages, and the ability to organize charts. This new feature allows pilots to select and order the charts prior to departure, making recalling them on the flight that much faster.
The map is now clickable for additional information, such as frequencies, hours of operation, and altitudes of airspace. The navigation log also got an overhaul that, with estimated time en route, auto waypoint sequencing, and estimated time of arrival, make it closer to a true moving map GPS than ever before.
Perhaps most important, ForeFlight said version 4—a free update for current subscribers—is considerably faster.
