Αν το scanner που διαθέτουμε είναι μόνο δέκτης και όχι πομπός τότε δεν υπάρχει περίπτωση παρεμβολών με καμία Παναγία μέσα και έξω από το αεροπλάνο.Αν ήταν έτσι τότε όλοι οι spotters που έχουν τέτοιο δέκτη θα έπρεπε να κάνουν τις τηλεποικοιωνίες μαντάρα ακόμα και γύρω απ'τα αεροδρόμια, πράγμα αδύνατο απ'τη φύση του.Από τη στιγμή που γίνεται λήψη ραδιοφωνικού σήματος και ΟΧΙ εκπομπή δεν τήθεται θέμα παρεμπόδισης των τηλεποικοινωνιών.

Personal Electronic Devices (PED) such as laptop computers, hand held scanners, and game players, while not intentional emitters, can produce signals in the 1 MHz range and can therefore affect the performance of avionic equipment. As navigation cabling and other critical wiring runs along the fuselage inside the aircraft skin, it's no wonder that passengers sitting just a few feet away are warned about the indiscriminate use of such devices. Since the thin sheet of dielectric material that forms the inside of the passenger compartment - typically fiberglass - offers no shielding whatsoever; and since commercial passenger jets contain up to 150 miles of electrical wiring, it is extremely important for passengers to heed regulations on the use of disruptive electronic equipment.
Obviously, such internal sources of EMI are particularly dangerous to aircraft because they are so close to the systems they might affect.
....
As if the many external and internal sources of EMI were not enough of a concern, a major EMI co-conspirator in aircraft is the aluminum airframe itself, which in certain circumstances can act as a resonant cavity, or a phased array. Behaving much like a satellite dish, the airframe can compound the effects of both internal and external EMI by concentrating transient signals and broadcasting the interference into nearby equipment.

In January 1993, on a flight from Denver, Colorado, to Newark, NJ, an aircraft lost all directional gyros (electromechanical devices that indicate orientation) at cruise altitude. The captain instructed the flight attendant to go through the cabin and tell all passengers to turn off their electronic devices. She reported back that about 25 passengers with portable radios had been listening to a Denver Broncos playoff game and that one passenger was also using a lap top computer. Within two minutes of the Captain's request to turn the radios off, the gyros had swung back to their correct heading. Later in the flight, several Bronco fans covertly resumed their use of the portable radios, and again the directional gyros began to malfunction. The radios were then confiscated and no further problems were experienced on the flight.
