Many aircraft used like the one in question would also be somewhat poorly equipped for inadvertent (or intentional) entry into IMC. You could argue that if you are instrument rated, you should be able to safely operate any IFR certified aircraft in IMC. However, I question whether this accident would have occured if the same flight was done in a G1000 (or similar) equipped aircraft.
Seriously???
How on earth can you say something like this??
Do you know the aircraft involved??
If you really think only flat panel cockpits are same for IFR then we'll ground about 90% of our airline fleet.
At this stage there has been no public information about whether the pilot and / or aircraft was instrument rated. Just a lot of conjecture by guys showing their ignorance.
