Automatic shifting to the graphical view after entering mandatory values removed. Minor design changes in the navigation bar to differentiate between shifting and action. Overlapping elements are better displayed when moving the yellow dot. When changing the range using a pitch gesture, a crash occurred very rarely, which is not reproducible to date. Error prevention, error handling and error correction have been added to prevent this from happening.

More Accurate Calculation Method According ICAO PANS OPS Doc 8168 a correction of 4 per cent height increase for every 10°C below standard temperature is safe for all altimeter settings for temperatures above -15°C. For temperatures of -15°C or below a more accurate tabulated correction or its underlying equation should be used. The calculation of all corrected altitudes is changed to the more accurate equation, regardless of the temperature. Additional Altitude, DIST To THR or DME An additional altitude may be entered to show its corrected value. The corrected altitude will be shown as a green horizontal line and/or a green dot on the vertical profile. Instead of an altitude you can also enter a "distance to threshold" respectively DME value. Adjustments To Different Screen Sizes Increased the number of entries in the distance-altitude table: - by 1 entry for iPad Pro 10.5 and iPad Air 3rd gen. - by 2 entires for iPad Pro 11.0 - by 3 entries for iPad Pro 12.9
