I never trained under a hood. I only have about 25 hours on a Piper Archer 2 flying VFR only!
At least for me I can look at the 6 pack and get an idea of what’s going on even if I flew into clouds. I would just hope I could get above, below, or out of them.
Maintaining a heading and keeping the wings level shouldn’t be that difficult as long as the instruments are operating correctly.
Well that explains it. Many pilots have died with just that attitude. You would last less than a minute in IFR without several hours of under the hood or goggles training. Just wait till you go under the hood, and I mean a good one where you cannot see out the bottom or sides.
It's difficult to disconnect what the eyes and instruments indicate with what the body and inner ear indicate. It takes practice. Doing it on a computer using Flight Simulator is easy because there is no conflicting information.
The first time I used a hood the instructor lifted the hood and I was in a high bank turn. I thought I was level.
