When a drone operator creates a flight on AirMap within the airspace of a D-NAS airport, a digital notice will be sent to the appropriate D-NAS administrators in the form of an SMS text message. This SMS text message is a push notification and does not allow for phone-to-phone communication between the drone operator and the D-NAS administrators. Please utilize "SMS" or "SMS ALL" commands found in the D-NAS dashboard to send SMS text messages to drone operators. Please note that all messages sent to and from drone operators from the D-NAS dashboard will be stored in the Message Log.
I've replied to the SMS messages on my phone, but I don't think the drone pilot is getting them.
