Another sometimes useful "incorrect" usage is repeating the call-sign near the end - as well as the location. It may take a couple more seconds but can save more time and confusion on follow up queries. Rigid formats definitely have their place but so does context/common sense.

Yes, speed ain't everything as this clip is at pains to show: https://www.youtube.com/watch?v=nuKFhfEOosg When I listen to local RPT pilots negotiate safe passage down among the unwashed and uncontrolled, I'm often impressed by their professionalism; unrushed, patient radio work with each aircraft they deem a possible threat. The comms alone can seem like a full time job, so lucky there are two of them up front. Anyway, as Gryder advocates (in the vid posted in the other circuit issues thread) they carefully engage each significant other to obviate ambiguity. If the RF is too chatty for that then the policy seems to be to hold away until it's clear. I often hear them breaking off their preferred straight-ins to join the circuit if they are in any doubt. In other words, it's not just a matter of declaring one's position/intentions and barrelling on in as if 'protected' by having 'followed the rules' ... or even just the recommendations.

Some busy circuit work, Dan Gryder style:

Speaking of exhaust valve failures, Peter Anson, writes here about his Sonex's Jab self-destructing. The outcome, luckily was very similar to that of the VL3's and its Rotax fail. The demise of my engine | Peter Anson – Engineering WWW.ANSONENG.COM

Some great video story-telling, including air-to-air shots from friends flying in company with the crippled VL3. The culprit (on a 750 hour engine):

OzRunways have a great series of videos on YouTube and the online manual is good too. And if you have any questions their support people typically get back to you within the hour. 15. Traffic 15.1. OzRunways Traffic System (in-app) Image 15.1 Left: Standard traffic popup Right: Popup with SkyEcho connected (iOS 13 or above required) The image above shows a typical Traffic Popup as accessed from the Maps page (see Traffic / Timers). OzRunways has implemented a traffic system based on the use of mobile (3G/4G) networks, we call this OzRunways Traffic. This is separate to ADS-B Traffic which is covered below. The way OzRunways Traffic works is as follows. If you opt in and are network connected, the App detects whether you are flying. If you are, it starts sending data packets to the OzRunways server via the mobile network. These packets hold your callsign, your position, heading and climb/descent rate. In addition, if you have an OzRunways plan open, that plan is also relayed to our server. The traffic system data usage is below 1 megabyte per hour (very minimal). The server receives the data and determines whether there are any aircraft in your vicinity and sends those aircraft back to your App, which are then displayed on the Map Page. The traffic displayed is the closest 18 actively flying aircraft to your current location. Each blue traffic icon / traffic bubble displays a callsign as specified in the Callsign field of the Traffic Popup. If no callsign is specified here, it will use the callsign from the aircraft profile in use. If neither of these options are available the dummy callsign ‘Unknown’ will appear. Below the callsign is the altitude relative to your current altitude in 100’s of feet. For example in the image at the top of the page ‘EFB’ is approx. 10,200ft above us, and ‘SYC’ is approx. 900ft below. Additionally, the direction of travel is indicated by an arrow on the circumference of the circular icon. In the figure, ‘EFB’ is tracking west, and ‘SYC’ is tracking northeast. The ‘Ʌ’ and ‘V’ symbols inside the circle indicate climbing or descending respectively. If you tap on a traffic icon it will momentarily enlarge, and if the user has an OzRunways plan active it will display that plan as a purple line. Note Relative traffic height is determined by comparing the reported GPS altitude of each device, therefore some margin of error is possible. This information is for situational awareness and should not be relied upon for traffic avoidance. Setup & Options The first time you start the app you are prompted to enable or disable the traffic system. You can turn the system on or off any time by tapping on the Traffic icon on the Maps page. If you wish to see other OzRunways traffic on the map you must also broadcast your own position. A single tap on the traffic icon reveals the traffic system options as shown above in Image 15.1. A ‘tap and hold’ on the traffic icon will momentarily enlarge all traffic bubbles on the map. Included in the traffic options is a slider to increase or decrease the size of all traffic bubbles. The elements of the traffic icon gives a visual indication of the status of both the OzRunways traffic system, and any connected ADS-B device. Image 15.2 Traffic icon legend Image 15.3 below demonstrates the appearance of the traffic icon under the following conditions: OzRunways traffic broadcasting SkyEcho ADS-B OUT broadcasting using callsign EFB, and squawk code 1200 Image 15.3 OzRunways and ADS-B OUT broadcasting Note The OzRunways traffic system will only broadcast your position to other users when it detects you are flying. I.e. the aeroplane symbol won’t be green unless you are flying. 15.2. tx.ozrunways.com (traffic wesbite) OzRunways traffic is also displayed on the website https://tx.ozrunways.com This is displayed on a normal web browser (not the app) and there is no restriction to the number of traffic displayed. Aircraft are illustrated on the map as blue traffic bubbles. Tap on any of these bubbles for more information. If a plan is available for the selected aircraft it is displayed in blue. Use the menu bar on the left of the page to access more options such as restricted area overlays and and various map overlays. The traffic website keeps a history previous flights you have completed (provided you had the traffic system switched on and working). Tap on ‘My Flights’ at the top of the website and log in with your OzRunways username to see your flight history. A list of flights is presented with some icons to the right of each entry. You have the option to share your flight via Twitter or Facebook, or you can preview the flight on the map or download it as a KML or GPX file. 15.3. ADS-B Traffic OzRunways supports ABS-B receivers that connect via WiFi and use the GDL90 protocol. ADS-B Receiver Setup Connect your iPad or iPhone to the ADS-B receiver in iPad Settings → WiFi. (Note: The ‘No Internet Connection’ warning is normal) The receiver should now be sending information to OzRunways. Check that the receiver appears in OzRunways → Settings. Own Ship If you are using an ADS-B receiver in an ADS-B OUT equipped aircraft, OzRunways can use the information from your ADS-B OUT signal for more accurate traffic height comparisons. OzRunways will first try to detect your ‘own ship’ signal by using the ICAO address entered in your aircraft profile. If this is not available then some logic is applied to nearby traffic to try and determine a match. When OzRunways identifies a suitable match it will indicate this by turning the traffic bubble green as shown in Image 15.4. ADS-B Receiver Troubleshooting If you have confirmed that you are connected to the ADS-B receiver via WiFi and it is still not working follow these steps: Open OzRunways and go to Settings → Device Options. Ensure that ‘Enable GDL90’ is switched on. The receiver should appear as a menu item in the Settings menu underneath ‘Device Options’. Tap to view device statistics including the number of currently visible ADS-B aircraft. Your iDevice can only be connected to one WiFi network at a time. If you usually ‘hotspot’ internet from another source (such as a phone) you may not be able to do this concurrently, unless you can connect to the hotspot using Bluetooth instead. Check that you are using the latest version of OzRunways in the App Store app. OzRunways receives regular updates with new features, improvements, and bug fixes. On the map page, ADS-B traffic is displayed just like regular OzRunways traffic but in a darker shade of blue (Image 15.4) Image 15.4 Traffic bubbles 15.4. Portable ADS-B Out Low cost, portable ADS-B OUT devices are coming to VFR aircraft in Australia! These portable devices allow all pilots to enjoy the benefits of increased situational awareness, with ADS-B IN receiver functionality to see other aircraft on your EFB, and ADS-B OUT functionality so these aircraft can now see you too. For comprehensive information on ADS-B Out devices and how they work with OzRunways, see this article on our knowledgebase: https://support.ozrunways.com/kb/en-gb/2-3rd-party-hardware-integrations The traffic system, including SkyEcho settings, can be configured directly on the Map Page as demonstrated above in Setup & Options.

The snappy little cartoons, below, from CASA are, I reckon, very effective in getting useful messages across. They're far more bang for the buck than, say, the webinar series also to be found on the CASA Briefing website. For example: https://www.youtube.com/watch?v=OUpU9ikmeEc&t=411s To me, even actual real-world seminars, more often than not, fall short of expectations. In any case, the usual 'house-keeping', fumbling, waffling etc. is not, any longer, acceptable in any kind of screen format. If the information in those webinar presentations is worth telling it should be re-purposed for publication on-line, i.e, professionally 'produced'. It wouldn't take much. Most of the resources are already in place. They'd end up a tenth of the length and ten times more effective. Production values - and educational outcomes - can't just be left to chance. The internet won't take it anymore. Still and all, there's lots of very good stuff on the CASA site: https://www.youtube.com/@CASABriefing/videos And these little cartoons are, IMHO, definitely on the right track.

DA strikes again ... but this young couple lives to tell the tale:

Another, generously provided lesson to learn from. (And another pre-flight checklist lapse.)

https://www.youtube.com/watch?v=2VjkCfSopEI Incident around 06:10 DESCRIPTION: "Couple of years ago during my second training flight on a very hot summer day, the canopy of the Extra 330LX that I was flying opened in flight and shattered. As you can see from the video, it was a challenging experience that could have been avoided if I had made a proper visual check before taking off. The canopy locking pin had never gone into the locked position, and I failed to notice it during my checks. I also made the mistake of going to the training camp right after recovering from COVID, without allowing my body enough time to fully regain strength. Additionally, flying without any eye protection made the flight even more challenging than it already was. The flight was a distressing experience, filled with noise, breathing difficulties, and impaired visibility. It took me nearly 28 hours to fully recover my vision. Aerodynamically, I’ve experienced some buffet and controllability challenges. Probably the most difficult part was to keep the power in, thus trading my vision and breathing for kinetic energy. Although due to all the noise it was difficult to hear what my coach was saying on the radio, one thing I've heard loud and clear "just keep flying" If you are a pilot watching this, I hope that my story serves as a cautionary tale and that you will learn from my mistake. I regret that it took me so long to share this video footage. It's not easy to put my vulnerabilities out there for you all to see. However, I have come to realisze how important it is to be transparent about our shortcomings and the lessons we learn along the way. To all my fellow pilots out there, fly safe."

What are air pockets? | Live Science WWW.LIVESCIENCE.COM And it is time for us to stop using the term? "Basically, there's no such thing. It seems to be a layman's term to describe certain forms of turbulence or windshear," Guy Gratton, an aeronautical engineer, test pilot and professor of aviation and the environment at Cranfield University in the U.K., told Live Science in an email. "I don't personally ever use the term. I don't think it's useful."

Popular media has deep pockets. (and shallow chat peeps ) https://www.youtube.com/watch?v=7rsB59MX8Xo

And this CBC journalist while getting closer to the right ROD insists that 2000 ft per minute is a 'catastrophic drop'. (at 01:30 - it's not advisable to suffer the whole thing) We need Blancolirio to explain that the 6,000' controlled descent happened 15 minutes after the turbulence encounter.

Yes, I think the aircraft would have broken up before attaining that vertical speed. (Blancolirio explains that the turbulence encounter caused a flight path excursion in the low hundreds. The subsequent 6000' 'plunge' was in fact a controlled descent.)

Channel 9 has the aircraft plummeting 6000' in five seconds. I believe that'd be a rate of 72,000 feet per minute! https://www.youtube.com/watch?v=umDhF1QMo7k

Blancolirio's take on it: (He explains that the turbulence encounter caused a flight path excursion in the low hundreds. The subsequent 6000' 'plunge' was in fact a controlled descent.) https://www.youtube.com/watch?v=0UYNFthOx1o

Yes, and LSALT is a concept used mainly in IFR ops.

I think the Terrain Overlay feature, by itself, is designed more for the real-time situation Turbo found himself in. But it's also used in planning in conjunction with what they call LSALT assistant. CLICK IMAGE FOR FULL REZ. "To open the LSALT assistant make a plan and select (tap) a leg, the leg will highlight yellow and the LSALT assistant button will appear on the Right Sidebar as in Image 12.1 The LSALT assistant uses the obstacle dataset from Airservices Australia, and terrain data from NASA. The assistant will find the highest obstacle and terrain, within the selected splay, for each leg of your plan and overlay these on the map. The assistant will then provide LSALT options based on this information with appropriate buffers, as well as route and grid LSALT options as applicable (as shown in Image 12.2). Opening the LSALT assistant also turns on the Terrain Overlay. The function of the Terrain Overlay when using the LSALT assistant is described below."

Turboplanner said: "..... What the WAC Chart has are Hypsometric Tints which show altitude in feet and metres. If you find during your trip that cloud has descended above you like a ceiling, the tints give a quick reference for a way out to be planned." Nowadays we can have hypsography of the dynamic kind (relative to our current position/altitude). 12. Terrain and Airspace DOCS.OZRUNWAYS.COM CLICK IMAGE FOR FULL REZ. "The Terrain Overlay is an aid to visualise surrounding terrain. In flight, yellow shades indicate terrain that is close to your altitude. Red is anything above you."
