You need to come out of the '60s!

Glass Cockpits

As aircraft displays have modernized, the sensors that feed them have 
modernized
as well. Traditional gyroscopic flight instruments have been replaced by
electronic Attitude and Heading Reference Systems (AHRS) and Air Data 
Computers
(ADCs), improving reliability and reducing cost and maintenance. GPS 
receivers
are usually integrated into glass cockpits.

Early glass cockpits, found in the McDonnell Douglas MD-80/90, Boeing 737
Classic, 757 and 767-200/-300, and in the Airbus A300-600 and A310, used
Electronic Flight Instrument Systems (EFIS) to display attitude and 
navigational
information only, with traditional mechanical gauges retained for airspeed,
altitude and vertical speed. Later glass cockpits, found in the Boeing 
737NG,
747-400, 767-400, 777, A320 and later Airbuses, Ilyushin Il-96 and 
Tupolev Tu-
204 have completely replaced the mechanical gauges and warning lights in
previous generations of aircraft.

I don't think any commercial airline or the military would fly w/o INS.
