Not having been there in the situation with the OP and his company, I would have to hear for myself what the ACP means by the term “traffic pattern”. I mean, in a single engine airplane or helicopter, even if you spiral down to a landing somewhere relatively close below you during an engine failure/fire, you’re going to have to set up some form of at least an abbreviated type of traffic pattern at the bottom end, in order to maneuver and get lined up at the appropriate place(s) so as not to over/undershoot the landing area.
Not knowing the situation, I don’t know whether the term “traffic pattern” is being used in the sense I’m using it here, or whether its being used to mean a proper-style rectangular traffic pattern with an upwind, and downwind, a base and a final……all flown at a singular altitude until descending on base leg.
In same example above, I have different techniques personally whether it’s a single-engine airplane or whether it’s a single engine-helicopter. In an airplane, which mostly glides well, I’ll shut an engine down that is on fire….shut the fuel off etc, as it may take time…depending on altitude…to reach a suitable area, and I’d prefer not to having things burning for long. Helicopters have the very cool ability to allow a pilot to take an airborne emergency, and turn it into a ground emergency pretty quickly. But in a single-engine helo, autorotation engine-off isn’t a good glide. Some single-engine helos autorotate/glide better than others due to being high versus low inertia rotor systems. For example, in the single-engine UH-1 Huey, with loss of the engine and resultant autorotation, the wide chord rotor blades and semi-rigid rotor system is high inertia and very efficient in storage of potential energy (so long as the pilot uses proper rotor speed management, and even if not, its forgiving), that the areas I can make an autorotative glide to, are anywhere from right underneath me, all the way to far out ahead in the front windscreen. Even then, I can get down to the deck and hover for a bit with no power in order to select an actual touchdown area that I want, because the Huey preserves it’s rotor speed so well.
Conversely, in a bird like a Hughes/MD 500/520 or such, with a very low inertia rotor system with narrow blade area, it doesn’t preserve rotor speed well when the powerplant stops or is shut down, and it doesn’t quickly regain rotor speed that is lost. In those helos, when the engine fails, the area you can autorotate/glide to is somewhere right underneath you, to somewhere in the chin-bubble area…..ie- not a great glide ability. And when you get down to a flare to touchdown point, you are touching down wherever is underneath you…..good or bad, since the rotor speed will disappear quick, hopefully you picked a suitable place. Where I’m going with this, is that in a single-engine helo, I personally don’t want to shut an engine down that is on fire and still producing power, because I can enter an “autorotative descent”, basically a rapid descent with power. And because nearly anywhere is suitable as a landing spot, I can be on the ground very shortly, and at least use the power still being produced to make a fast descent but managed touchdown, instead of having one emergency (fire) and turning it into two emergencies (fire + no-power autorotation). Only big thing to have to keep SA on during a rapid autorotative descent with power, is to avoid overspeed of the rotor system by managing it correctly.
So yeah, different techniques for different situations. In all the above scenarios, some form of maneuvering to set up for final approach……a type of pattern, no matter how abbreviated……will have to be done. Whether or not this is the definition being used by the ACP and there’s some form of miscommunication going on, I do not know.
