- An unmonitored descent into the surface.
Unlikely over the sea but very possible over higher terrain.
With both the G1000 and the Avidyne you will get the usual "five hundred" aural warning. Of course you might ignore that as well but it is quite attention grabing especially if you are not expecting it. Unless you have set a very uncomfortable rate of descent plenty of time to realise what you did wrong.
Even over the land the TA will give you a warning in this scenario (although you would not want to rely on it).
- Loss of control, Kennedy-style.
With the Perspective the Level button is an option that has not been available before. It is billed as a get you out of trouble in a spatial disorientation situation.
