Updates in 1.6.1 include the following: 1. Wind chart now includes a wind direction colour band for quick wind direction trend identification. The colour band represents the direction the wind is coming from over time. Colours follow a circular compass scale (North → East → South → West → North), so similar colours indicate similar wind directions, and smooth colour changes show gradual wind shifts. Sharper colour changes indicate more marked (less stable) changes in wind direction. 2. Changed Weather (WX) provider due to previous WX provider ceasing operations.

New in this release of ok2fly: 1. CASA Micro User Category - You can now select the MICRO pilot type when flying sub 250gram RPA. The rules for MICRO RPA are different to other larger RPA and pilot types. You can fly your MICRO RPA in the area around controlled airports up to 150 feet without authorisation (does not included the arrival & departure SPLAYS). 2. Displays configuration and active overlay settings in map footer. 3. Added weather forecast in query details for day of flight (if available). Subscribed users also have the option to see a detailed 10-day weather forecast. The detailed weather forecast includes the daily temperature, winds, rainfall, visibility and weather data tabulation. Hourly weather charts also display timing of twilight, daylight and nighttime. 4. Subscribed users now have access to additional overlays. The new overlays include a Dynamic Grid (1000km to 1m), 3D Terrain, 3D Buildings and the ability to hide the active NOTAM layer. A Ground Level (street) powerlines overlay is now also available. 5. Subscribed users can now display hybrid aeronautical charts. The hybrid charts in crude the ERC Low and WAC/VNC/VTC. Issues fixed in this release: 1. Lightning overlay has been updated to use new lightning data source. 2. Weather radar overlay now correctly dismisses when deactivated. CASA Compliance: Version 1.6.0 complies with the CASA operating rules version 4.1.

Version 1.5.1 includes the following changes: - Improved tracking of subscriptions across platforms - App now displays app version and operating rules in the footer of each query - App now displays a base set of overlays for recreational users (no subscription required to access these overlays) - Updated message reminding users that subscriptions need to be cancel via the platform subscription provider. - Fixed Aircraft tracking display. - Fixed TRA display processing. - What3Words functionality has been deprecated

Version 1.5 contains a number of updates. 1. The mapping engine software was upgraded to the latest SDK version. This was quite a large change and as a result you may notice some slight differences in the way the map behaves. Overall though, the look and feel is almost identical to previous versions of ok2fly™. 2. The app and backend support functionality now support the extended CASA Airspace Authorisation trial. This includes the ability to automatically authorise flights in the Sydney harbour restricted area R405 and Sydney airport (YSSY) envelope. Although this is principally a data update the changes made will facilitate the rapid incorporation of future Airports and Restricted areas as they are included in the trial. 3. Users are now able to measure distances on the map using a 2-finger tap and hold gesture. When the user executes the two finger tap and hold on the map, a ruler (dashed line) will be displayed. The ruler will be labelled with the distance in either Metres, Kilometres, or Nautical Miles between the ends. While maintaining the 2-finger touch, the user can position the ruler ends as appropriate by moving 1 or both fingers. The ruler label will be updated in response to any change to the ruler ends. To remove the ruler simply tap on the map. 4. An additional overlay has been added. The ACMA communications data now has a corresponding overlay that displays the known location of communications infrastructure. Infrastructure may be cell towers and any other communications apparatus that may constitute a potential hazard for UAV. Information is displayed as Red or Blue dots where Red indicates a location accuracy of within 10 metres and Blue corresponds to Unknown accuracy. The ACMA data is updated daily. Note: The overlay will be activated a short period after the app has been released.

Version 1.4 ok2fly incorporates a major change to way Flight Time is handled. In previous versions of ok2fly, Flight Time was based on the time specified or Current Time for the location and time zone of the device. When planning local flights this did not present a problem, but when planning flights across time zones (e.g., interstate) the start time would need to be adjusted to include the time offset relative to the device location and time zone. In some instances, this has created confusion around the actual start and end time of a flight. To rectify and streamline the situation, the Flight Time is now based on the time at the flight location. Therefore, when a time is specified, the time will represent the equivalent time of day at the planned location of the flight. The app will display the calculated time zone against all times and inform the users if the time zone is different to the user current location. For example, for a pilot currently located in Canberra planning a future flight in the Glenelg area of Adelaide, entering a Flight Time of 1630 signifies 1630 (ACST).

Version 1.3.2 of ok2fly contains the following enhancements: - ok2fly now integrates with AvPlan-EFB. Subscribers to ok2fly can now run AvPlan-EFB using a shared subscription. - The shared subscription is equivalent to the AvPlan VFR Plus subscription. This includes access to Airservices Charts, Airfield diagrams, Aviation Weather, ERSA, AIP, MOS and other aviation documentation. - Users can launch AvPlan-EFB from ok2fly via 2 methods: 1. If AvPlan-EFB is installed and the user has an ok2fly subscription an AvPlan-EFB button is displayed on the map. If the user taps the button AvPlan-EFB is started and will display the EnRoute/Map pane at the same location as ok2fly. 2. When a subscribed user opens the airport information pane, an additional "AvPlan" button is displayed. If the user tapes the button AvPlan-EFB is started and will display the Terminal pane entry for the same airport as open in the ok2fly airport pane. For enhanced utility, on suitable iPads, you can run ok2fly and AvPlan-EFB side-by-side using the Spilt-Screen Multitasking feature available in iPadOS.

This version of ok2fly contains the following fixes and enhancements: - The Request Authorisation window now highlights required information in red text. - The Request Authorisation window warns the user when the RPA device type is "Unknown" prior to actioning an Airspace Authorisation. - The Mission Manager Authorisations and RPA Devices lists now provide brief usage instructions on how to manipulate list items. - The Mission Manager Authorisations list will display the word APPROVED as the status value for pending approved Authorisations. Previously the word PENDING was used, which could be construed as the authorisation is still pending approval. - ok2fly will now display either APPROVED or REJECTED as the starting authorisation state. REJECTED authorisation are included for reference purposes only. - Correction of spelling mistake in pop-up title - Saved pilot type is restored when user has an active subscription. If no subscription the pilot type will default to Recreational. - When a user signs out, all post sign out queries are treated as an anonymous recreational user queries until such time as they login using valid credentials.

Changes in this release of ok2fly Version 1.3.0 1. Changes required for transition to new version of MOS 101. Changes include: - More precise definition of runway Splays  - More precise definition of airport Envelopes - Transition to RPAS Operating Rules version 2.5 2. Changed Airspace Authorisation Requirements. Approved REOC's are now required to enter the RPA type and the mission flight profile when requesting airspace authorisations. Functionality has been added to the app to facilitate the RPA device type entry (from CASA specified list of types) and flight profile (from CASA specified profile list). Users with existing RPA definitions will need to review and update existing RPA definitions prior to future authorisations. 3. Splays and runway based envelopes are now displayed for non-controlled and controlled airports (349) where runway information is available from Airservices Australia. ok2fly subscribers will be able to view an additional 1469 airport runway splays and runway based envelopes.

Version 1.2.2 includes the following additional functionality: 1. This version implements the Apple mandatory requirement (as of 30/6/2022) for a user to be able to permanently delete their account and associated data. A new option has been added to the MANAGE ACCOUNT section of the Settings option to facilitate this requirement. Deletion is permanent and any associated data stored by ok2fly is deleted. On completion the app state will be reset to recreational use, i.e. as a generic non-identifiable user. Users can create a new user using the same previously used login credentials after deletion, but they will be treated as an entirely new user. 2. The query details listing now exposes the What3Words for the selected location. The What3Words displayed can be quoted as the proposed location for a flight and entered via the search window prefaced by "///". For example, for the location "antibiotic.crowded.descending" enter "///antibiotic.crowded.descending" in the search field and select the matching entry from the list of close or matching options displayed below. 3. Fixed an issue in Airspace Authorisation where maximum altitude height - Meters / Feet are incorrectly displayed.

The following new functionality is included in release 1.2.1 of ok2fly™: Two new Active Overlays and three Static Overlays have been added to ok2fly™. Each of the new overlays are accessed via the Overlays button on the lower righthand of the map display. ok2fly™ will indicate when active overlays are active by displaying an icon in the status bar at the bottom of the map along with the corresponding elapsed time measure. ACTIVE OVERLAYS Weather Radar Overlay – The weather radar overlay is a live display of precipitation events over the previous 60-minutes. The weather is animated as sequential 5-minute snapshots representing the 60-minute period. The intensity of the precipitation is depicted using a colour gradient of green through to red, where red represents the highest intensity. When active a cloud icon is displayed in the status bar along with the number of minutes (-ve) since the snapshot was created. Lightning Overlay – Lightning events are displayed on the map as lightning icons. The icons are oriented, and colour coded to represent the type of strike, namely Cloud-to-Cloud/Cloud-to-Air/Intra-Cloud (Blue Outline/Horizontal Icon) and Cloud-to-Ground (Red Outline/Vertical Icon). Given that there can be many lightning strikes the strike data is downloaded progressively as the strikes occur. Ok2fly™ accumulates up to a maximum of 60-minutes of strikes. The Lightning overlay works with or independently of the Weather Radar overlay. - When the Weather Radar overlay is active the accumulated strikes are animated in time with the weather radar and the status bar cloud icon is changed to a cloud and lightning icon. - When the Weather Radar overlay is not active all accumulated strikes are displayed. The opacity of the strike icon is adjusted based on their age. The older the strike the lower the opacity. The status bar will display a lightning icon along with the age in minutes (-ve) of the oldest strike. Notes: 1. As the term implies, active overlays are actively downloading the data used to generate the overlay. In mobile applications without access to Wi-Fi, the data downloaded will be via cellular data and count towards cellular data usage. 2. The time taken to fully display an overlay will depend on available network performance. STATIC OVERLAYS Non-Registered Airfields – This overlay displays all currently known non-registered private airfields. These airfields are not registered as ALA’s with Airservices Australia and typically facilitate the operation of GA aircraft into and out of the specified location. When this overlay is selected a light blue filled circle is displayed along with a generated alphanumeric Y code and airfield name. The centre of the circle is the supplied airport reference point. Uncontrolled Env & Splays – This overlay displays the outline of the airport Envelope and Splays as specified in Part 101 Division 9.1 RPAS operations at or near non-controlled aerodromes. The envelopes and splays are only displayed for non-controlled airfields (registered and nonregistered) where runway information is available. Heliport 1.5NM Envelopes – This overlay displays the 1.5NM envelope around heliports using the heliport airport reference point as its centre. Although safety apps are still required to use a 3NM envelope for heliports, this overlay displays the envelope specified in Part 101 Division 9.1 RPAS operations at or near non-controlled aerodromes.

Version 1.2 of ok2fly includes the following new features: 1. Active Overlays The Overlay function now includes a new section "Active Overlays". The first active overlay added is a live aviation traffic display. The overlay displays tracked live aircraft* with in 180 nautical miles and up to 15,000 feet AMSL of the current map centre. Each aircraft is depicted in its current location along with its altitude** and a climb/descend indicator as appropriate. To minimise network traffic, position updates are limited to every 10 seconds. However, so the user can appreciate the continuing movement of the aircraft in between updates, ok2fly simulates the track of the aircraft based on the last known ground speed and heading. The simulated updates provide an interim and approximate location of the aircraft while in flight. The position of the aircraft will however snap to the actual position and heading when the next position update is received. 2. App Version Number and Attribution The last item displayed in the Information window is now “About ok2fly™” information. The About ok2fly™” information lists the current version and build number along with data attribution information required to acknowledge the data sources used in ok2fly. 3. Fixes - Fixed issue where on some devices the user would erroneously receive a "No internet" warning on start-up. * The live data feed comprises multiple aviation data feeds and is not guaranteed to contain all aviation traffic. ** Altitudes are rounded to the nearest 100 feet.
