Can we use position tracking feature with Wi-Fi iPad?

Hello,

Wi-Fi only iPad models can position themselves by using Wi-Fi.

In order to use GPS when not on wifi you would need cellular

Unless the iPad can be connected to a wifi hotspot, yes, you would need cellular. But will there be available cell service when you are in the air?

Only WiFi & Cellular models of iPad have a built-in GPS receiver.

WiFi Only models of iPad are entirely dependent upon geographical lookup against a database of WiFi networks and public IP Address of the network to which to device is connected via WiFi. As such, without an active network connection, a WiFi Only device cannot determine its location.

However, a WiFi Only iPad can be augmented with an external dedicated GPS Receiver - connected via WiFi.

If using your iPad in a typical GA cockpit, a GPS & Cellular iPad is likely to be the better choice - mindful that the iPad will need good line-of-sight to provide a good positional fix (obstructions will result in whose performance due to increased DOP).

If using a WiFi Only iPad for GA, you will require an external GPS receiver. I would perhaps avoid this approach to protect your avionics from possible interference.

I hope you find this information helpful in informing your decision.
