Yes, the pilot was low and flat, but that doesn't mean that hitting a car is his error.
Not going to let the pilot off quite that easily, even if he couldn't see the car. Here's why.
- If that road is a known problem, pilot must adjust approach path to keep that road in sight (steeper) or plan to touch down further down the runway so the road is cleared with a reasonable height margin.
- The above is driven by the standard measure of any pilot decision: Is the desired outcome of the maneuver (a safe landing) ever in doubt? If so, an immediate go-around is intrinsically demanded. Don't accept "I don't know if this is going to work out". Firewall it and pick a better approach where you can see that darn road.
My doubt of the outcome of the landing starts far enough back in that video, that a go-around would have missed the car.
The car isn't even in the frame and he's low. You see him try to fix it with pitch at the fence line which shows a thought process problem, maybe a fair one for a new solo student; he doesn't realize that any slower will increase his descent rate without adding power.
He's behind the power/airspeed curve, and pitching up makes his approach steeper, and shorter. You can't stretch a glide at that speed with pitch alone. You've got nothing to trade, airspeed-wise. The ASI and VSI are both going to drop.
I know he's a student. I know it's hard at that point in training. But too slow and too low is go-around territory. At least it's "cram in a handful of power" territory.
He may not have been able to see the car, but he knew the road was there and you just can't assume there is nothing on it.
My thoughts...
Overall fault: Car driver. Without question.
Accident prevention possible?: Yes. Pilot.
There's times things that happen aren't your fault as a pilot, but it's still fixable.
The "wildlife on runway" example is another similar circumstance. They're not going to take your license away for a deer darting in front, but if it did it far enough down the runway ahead that you can go around, you should save the plane.
That's just what a pilot must do.
