To be sure, airlines do have efficient communication systems in place, noted Greg Waldron, Asia managing editor of FlightGlobal.
“Airplanes are always transmitting their locations via their transponders and communicating through radio. The case of MH370 was exceptional since the transponder was turned off. Suggestions for the transponder to be left on 24/7 are typically disliked by pilots since they want to be able to isolate it if the situation calls for it,” Waldron said
“Uploading every aircraft parameter, every aspect of the airplane like fuel and hydraulic levels, engine controls, 99.9 percent of that time, you don’t need that data,” Waldron added. “It’s a good idea in principle, but really, given the number of flights that take place daily and the minor eventuality of an accident happening, it’s just not a practical investment for airlines.”
Airlines aren’t likely to use much of the extra cash to fund technological improvements since their priorities lie with reducing expenses, Denny Kelly of Kelly James and Associates said.
He advocates an alternative funding solution instead: Slapping an additional tax on passenger tickets, around $20 per return ticket, in an effort to source funds.
