In a RADAR environment you could use DR initially then vectors. But in ZQN with the loss of the GNSS position information in the valley you are up the creak without a paddle.
Yes, you do need an INS and ATR have got an INS which replaces an AHRS unit to provide that coasting ability.
It is what ATR are testing for approval at the moment. The new -600 sim in Auckland will have the ability to start AR training very soon.
