Not really. Instrument training is emphasized a lot more in the Navy than in the Army. After flight school, the emphasis continues. I now have about an equal amount of time flying in both services. I have two to three times the actual instrument hours of the next closest guy in the battalion. He has 2000 more total flight hours than me. I got most of that in the Navy. Most guys in the Army will end their flying careers and never get 50 hours of actual instrument time.
The Navy has a higher attrition rate in flight school. It is also easier to get into Army flight school. If you cluster plot the quality of Army aviators arbitrarily on a scale of 50 to 100, they would be fairly evenly distributed. If you then took Navy helicopter pilots and plotted them on the same scale, they would cluster more toward the upper middle of the scale. The best Army pilots are every bit as good as the best Navy pilots. The worst Army pilots probably would not have made it through Navy flight school.
Yes, you can tell the difference.
The Army lands on boats, just not nearly as often. And we (collectively) don't do it as well. But we do things on an everyday basis that the Navy does rarely. HAATS is another thing the Army does well.
Flight school is not something the Army does particularly well.
Have three former army guys in my squadron and completely agree. Throw in what I saw from the Alabama accident, which was more of a negligent homicide, and yeah. Army doesn't do instrument flying.
