"I've never been asked to fly an assigned track by ATC...............IRS is over 70 years old. GPS has been widely available for over 30 years. Time enough for procedures to catch up to technology. It's been a long time since I saw an IFR aircraft that didn't have at least a GPS, which means 99.99% of IFR aircraft can fly track............
It's ridiculous that in this day and age we are using magnetic heading instead of true track, but some day we'll get there."


Using magnetic must be a PITA in places such as Canada, but isn't it because we still have basic C152s etc. using the same runways as IRS/GPS aircraft? And if all the ADIRUs + GPS failed, (yes, I know....), even an A320 has a normal magnetic field powered compass.
