"The student pilot in AEM was using ‘AvPlan’ electronic flight bag (EFB) software installed on an iPad."
"The iPad in AEM was fitted with a SIM card capable of providing the required data connection to AvPlan live, but was not fitted with an external ADS-B receiver."
"Due to the damage to the tablet sustained in the impact, it was not possible to recover data from the iPad to determine whether the traffic information overlay display was selected at the time of the collision."
