Back in the day, yes. He isn't doing anything remarkable really. Yes he should add a little altitude, but if this is who I think it is, this is really a tame Demo. There is or was a German Army Sargent that would end his aerial demonstrations by coming to a very high hover and face the crowd. He would dip the nose of the aircraft with forward cyclic, grab an ass load of collective and put the cyclic in his stomach and make the old BO do a back flip from a hover.
We had this game at Ft. Hood years ago. ( I was in 3-6 Cav and we were the first fielded with Apaches, so the rules were kind of loose back then) The game consisted of chasing Jack Rabbits at night under night vision system. If you were good, the rabbit couldn't get away from you, but you had to stay quite close to it or it would hunker down and try to hide. You could chase it until it fell over dead. I expected it would just tire out and quit, but it would actually run itself to death. Land, get out and put it in the helmet bag and go find another.
We would also practice ACM or air combat maneuvering. There has always been a restriction from aerobatic flight in the Army AR 95-1, but our commander didn't view ACM as aerobatic flight. Any helicopter is good for only two turns, then you are down to an airspeed that you are abusing the hell out of the tail rotor to turn. Interestingly the AH-64a had enough power if at 15,000 lbs gross weight to have a 5,000 ft. per min rate of climb at 80 kts, but didn't have enough power to maintain a 60 degree turn at 120 kts (cruise speed) helicopters bleed an enormous amount of speed in a hard turn.
The only thing I saw this BO do that might have been hard for an Apache was the neg. G pushover. The Apache had a fully articulated main rotor where the BO had a rigid rotor. In a hard neg. G push over the Apache main rotor would "rub" the canopy. This is the reason an Apache was limited to -1.5 G's, but that could be exceeded if you eased into it. neg. G's are uncomfortable and the average old Cobra driver would absolutely break out into hives if you put them in neg. G. In a semi-rigid rotor system, neg. G wasn't survivable, it resulted in mast "bumping".
