New: Support for twin-engine configurations on a single display page. New widget styles are available that display both engines' information on a single gauge.

Note for existing twin-engine customers: These updated twin-engine monitoring capabilities superscede the legacy capabilities. In software versions before 16.2, each EMS module was tied to a single display, requiring two displays to monitor both engines. In version 16.2 and later, each display page (100%/50%/20%/bottom bar) are configured to display gauges from both engines. Additionally, all displays' pages will be identical. In other words, the display of both engines should be configured on each page layout, and those pages are universal across screen. The ability to display only one engine per dislplay is not supported in 16.2 and beyond. However, legacy twin-engine settings will continue to work as-is until changes are made to EMS settings. Contact Dynon technical support for additional details.

Improved: To remove ambiguity, vertical speed required guidance is only overlaid on the VSI when HSI source is set to SkyView.

Improved: Center frequencies were previously filtered from appearing on the ATC button of the comm radio unless you are in-air. The restriction has been removed and center frequencies will now appear on the ATC button regardless of whether you are in-air or on the ground.

Improved: Starting with cycle 1702 of PocketFMS databases, SkyView will draw certain non-US airspaces of the following types according to their airspace class rather than airspace type if class information is available, and otherwise, by type:
- CTA: Control Area
- CTR, SRZ: Control Zone
- TMA: Terminal Control Area
- TIZ: Traffic Information Zone
- TIA: Traffic Information Area

Improved: AWIS frequencies are accessible from the ATIS button on the comm radio and visible on the INFO page COM tab. This primarily affects non-US customers using PocketFMS databases.

Improved: FIA frequencies are accessible from the ATC button when in air, and are shown on the INFO page COM tab labeled as CENTER. This primarily affects non-US customers using PocketFMS databases.

Fixed: To/from and desired track indications could be reversed in rare cases (flight plans that involve polar routes).

Fixed: Visiting the plates tab under info would cause the map window to go into expanded mode, which would cause it to incorrectly displace half the bottom EMS and the info column.

Fixed: When editing the weight at a station on the weight and balance page, overweight or otherwise out of bounds conditions would not turn red until editing was completed. The value now changes to red during editing.

Fixed: Traffic on HDX displays could be displaced a small amount on the horizontal axis.

Fixed: Extremely quick-fingered pilots might be able to press a key (such as direct-to) a second time before the first press is processed, leading to unexpected behavior.

Fixed: Under extremely rare circumstances - when a NAV radio is active, tuned to a VOR or ILS and providing an ident that matches a nearby facility in SkyView's aviation database, and an aviation database is imported - the SkyView could restart and trigger an erroneous “system event 3” alert.

Fixed: Default widget config for EMS arc widgets with corner values, such as the default, bottom EMS band, are now saved in exported and imported configuration files.
