Legality aside, will cellular data work on an iPad in flight at low altitudes?

I am planning a trip from the east coast to the west coast this summer in a PA-11. For various reasons, Gross weight limitations mean I will be flying solo. The PA-11 does not have an electrical system. I will have two handheld air radios and a garmin gpsmap 496 with siriusXM weather service on the garmin. I will have an iPad and iPhone both running foreflight basic. Will the iPad or iPhone be able to get updated weather inflight if I am flying about 3000 ft agl?

I will be using paper maps. Due to my low experience in taildraggers, I worry about landing at airports above my crosswind capability and for the most part have identified alternate airports with different runway directions to get better crosswind components. However, I would need to know the wind direction in flight to decide which airport to land at.

So legality aside, will the cellular data or cellphone service work on an iPad or iPhone in flight for flight safety purposes?

You only need to look at your 496 WEATHER info if your airport is on The System

My experience is that cellular service generally works at 3000 AGL and below, although that can be spotty and variable depending on terrain, obstructions, and tower density, so I wouldn't count on it.  However, the XM weather on your 496 should fill your inflight need for surface wind at airports along the way equally well.

And if your airport isn't in "the system", it won't show up via any cellular data on your iPad.  The only case where that might be different is if there's an ASOS/AWOS that can be reached by phone but isn't reporting in the system, and I don't know if there are any such airports.

Get an ADSB IN device - weather isn't perfect but it is reliable as long as you look at the update times.  Most work with Garmin and Foreflight.
