Currently I am mainly flying the airplane without GPS, so I decided to order some things for better situation awareness.
First of all, I ordered an iPad for using it with foreflight (which works only on apple tablets/phones). At the end I’ve chosen FltPlan Go instead, but anyway flying with EFB is easier: I can read METARs, use airport diagrams for VFR and approach plates for IFR. I still prepare paper charts for every flight, but now they become my backup source of information.
BTW, FltPlan Go is not available in some local App Store versions (for example, it is not available in Russian App Store).
I also bought stratux: it is an ADS-B device combined with AHRS and GPS. As a result, I see the weather and traffic data, and have a backup attitude indicator. It is not a primary source of information, but one more safety measure.
Summer Florida brings a lot of thunderstorms, they are forming quickly, and typically there are more than one cell. In case of thunderstorms we can see “VCTS” in the METAR: it means “thunderstorms in the vicinity”. We see that sign almost every day after about 2pm, but before 1pm it is usually safe, and the sky is clear.
I have planned to fly North-East and back before large cumulus and cumulonimbus clouds would start to form, but today it happened earlier, and I saw some towering clouds from the destination airport. They were still rather far to the North-East from me, and South-West direction was still clear, so I took off and turned to the South-West.
After about 15-20 minutes some cumulus clouds ahead turned into small thunderstorm cells, so it was better to deviate. After some more minutes I saw a really large dark cloud of about 6000 feet height in about 25 miles, and some more not so big cumulonimbus clouds.
I was looking for aerodromes nearby all along my route just in case if the situation becomes worse, but fortunately thunderstorm cells did not form a long line, so flying about 10 miles straight to the South did the job to safely avoid them.
It was a bumpy ride anyway, and wind gusts became about 16 knots according to our weather station.
In about 1 hour after landing thunderstorm cells formed a continuous wall almost along the shoreline with about 10-15 miles shift to the East. The wind became stronger, but those cells was not moving: moist air from the ocean fed them. Further to the East the clouds were dissipating, occasionally forming some new not so strong cells. And all this lasted for some hours.
That kind of weather is typical for summer Florida. It’s true that almost every day is flyable, but in summer it’s better to be on the ground after about 2 pm.
