I was interested and not surprised to find that psychologists and cartographers have recently discovered that using small digital maps (of the type found on smartphones, tablets, navigation avionics devices, etc) actually impairs our spatial awareness. This ties-in with my own experience of navigating by "following the pink line" (on my Garmin, or iPad GPS etc), happily and accurately reaching my destination airport, "...good, airfield in sight (tell the tower, etc)", but then suddenly faced with the mental gymnastics of "****, how do I line-up in the right direction for my overhead join".
Of course, being prepared in advance for the correct arrival is the appropriate response (I hear you shout), but on occasion I admit I've been caught-out in the slightly bizarre situation of having 100% location-awareness (from the GPS), and almost zero spatial awareness. Yes, the "OBS" functionality (if your device has it) helps a *great* deal in this scenario...but only if you remember how to activate it in the heat of the moment... ("what switch or knob on the Garmin 430 does that again?") etc.
...and Georg Gartner, a cartographer at the Vienna University of Technology in Austria argues from similar experimental evidence that reading maps on cellphones can affect our spatial cognition. Specifically:
"A map on a mobile device or in a navigation system leads to less accurate mental maps and a lower ability to act in the real world".
...Yikes, just as I was contemplating adding GoogleMaps to my newiNavCalc mobile app...which, on balance, I will probably do for the convenience of finding waypoints in pre-flight planning, but not for navigation.
[Anyway, just like everyone else, I always fly with complete, up-to-date, paper charts folded in the correct manner for my given route, and easliy accessible in the cockpit. Right ?]
I'm delighted to announce that iNavCalc is now available for the iPhone, iPad, iPod Touch, or any Android device (click the appropriate link above, or search for iNavCalc on the App Store or the Google Play Store, respectively).
This powerful (yet *FREE*) app makes it even easier to generate your PLOG by email. Follow three simple steps (requires only one hand / one thumb !):
Enter desired route as list of waypoints separated by spaces e.g.: EGNS EGNH
Click "Get PLOG..."
A few moments later, retrieve your PLOG, MET, GPX, and FPL files as email attachments
In a recent post I extolled the virtues of the Garmin AERA 795, and its synergies with my free email-based flight nav planning app, iNavCalcwhich now supports importing and exporting of Garmin-format routes (".fpl" files).
So far, so good. But I was still left with the nagging problem of having to
only program the Garmin SD card when at home (using my desktop PC with its built-in SD card reader); or
lug my laptop around just to be able to program the Garmin on-the-go (at the airfield, in the cockpit before departing, etc) via the laptop's SD card-reader.
THOSE DAYS ARE HAPPILY BEHIND ME, and I just thought I'd share with you my excitement at being finally free of my PC (at least when it comes to flight planning). For no more than a few pounds/dollars/euros, here's how I have freed myself:
First, here's a reminder of my essential kit for flight nav planning and navigation:
Garmin AERA 795 for in-flight navigation (in my humble opinion, blows away my iPad in terms of usability, robustness, stability, and performance in the busy cockpit environment -- pricey, yes, but you get what you pay for).
Samsung Galaxy S2 Android smartphone for planning my routes via iNavCalcand nothing more than a 3G connection (to receive email on the phone).
Next, I recently purchased the following pieces of kit to complement the above:
A simple portable USB SD card reader (from Kingston)
A USB OTG (On -The-Go) cable for connecting the USB SD card reader to the Galaxy S2. Quite possibly the best £1.69 I've ever spent.
...and here's how all that kit hangs together, completely freeing me from my PC:
I use the Galaxy S2 smartphone with iNavCalcto plan my route (literally using only one hand / one thumb) via email. When done, I automatically receive an email with an attached ".fpl" file containing my desired route.
I open the ".fpl" attachment on the smartphone, and save it to the local micro SD card ('permanently' installed in the phone). This is where the Gmail Attachment Download app does its thing: it enables files of any format -- such as the relatively obscure ".fpl" format -- to be downloaded and saved (without this app, the Galaxy S2 would not allow me to download an unrecognized file format such as ".fpl").
I plug the OTG cable into the Galaxy S2, and connect the portable USB Card reader to the other end of the cable. I then insert the SD card from my Garmin AERA 795.
Using the ES File Explorer app, I copy the ".fpl" file from the phone's internal micro SD card to the Garmin SD card in the external reader [note: I did, of course, try copying directly from the email attachment on to the mounted Garmin SD card. The file-copy worked fine: but then the Garmin somehow couldn't import the file. Odd. I will take a closer look if/when I have time. Meanwhile, 'bouncing' via the internal micro SD card works fine, adding only a few seconds to the task].
The whole process takes a matter of minutes. Also, I can just as easily go the other way: export route(s) from the Garmin into my phone and then on to wherever...e.g., Google Drive (for my own later re-use), or iNavCalc's routes database (for sharing with anyone)...
Of course, all of the above would be unnecessary if I could communicate between the Galaxy and the Garmin via Bluetooth and utilise some file-sharing protocol....maybe that will come in time, but for now, I am happy (and free).
Final note: all of the above is avoidable if I simply use my iPad for everything. That has certain appeal: I can use iNavCalc to generate/share routes via email, and seamlessly import them to SkyDemon or AirNavPro etc., on the iPad for navigating. In fact, this is what I used to do -- until the iPad let me down once too often in the cockpit, and I went the Garmin 795 route (and haven't looked back since).
Related: this experience exemplifies one enormous advantage of Android over iOS: the ability to configure your devices to do what you want to do with them, not being restricted to do only what Apple allows you to do with them. Try reading an ".fpl" file via the iPad camera kit's SD card-reader, for example. Impossible. Forbidden by the Apple software (unless you jailbreak your iPad, which is not an ideal scenario -- especially on a device you may then go on to use for navigation !)
