It is the only full-spectrum helicopter flexible enough to satisfy every training flight requirement, from fundamental autorotations to more advanced Search & Rescue procedures and Night Vision Devices, for example.
(Not many instructors will stop short of a full break unless you fly something with a nasty reputation.) Helicopter pilots can anticipate low-rpm recoveries, governor-off operation in models so equipped, recognition and recovery from settling with power, and of course autorotations. Emergency procedures, including simulated forced landings, are guaranteed in both.
autorotations and recovery from vortex ring state close to the ground
His maneuvers were coordinated and delicate in the pattern, so I decided to move on to autorotations. His autos were fine, but his power pull and yaw control close to the deck were about as expert as a palsy victim doing brain surgery with a monkey wrench (well, maybe he wasn't that bad).
Emergency procedures included touchdown autorotations, hydraulic-off landings, and tail-rotor failure procedures.
There must be a quick fill option at the NTSB for R22 accident reports that types, "The certified flight instructor (CFI) and student pilot undergoing instruction were conducting 180-degree autorotations in a helicopter ..."
The basic helicopter curriculum includes approximately 40 hours in the TH-57B Sea Ranger to familiarize the student with hovering, takeoffs and landings, autorotations, and VFR navigation.
The inertia stored in its heavy rotor is there to cushion emergency landings, known as "autorotations." However, such features come with a cost: $600 to $950 an hour for instruction; as much as $1 million to purchase new.
Helicopter pilots should substitute normal, steep and shallow approaches for the takeoffs and landings, put in time practicing autorotations and low-rpm recoveries, and approach any simulated hydraulic failures with considerable caution.
We opted not to take a full bag of gas because of the aircraft weight, environmental conditions and anticipation of doing practice autorotations. I stopped the refueling at 1,500 pounds, which gave us a gross weight of 13,577 pounds (about 1,200 pounds under our NATOPS max of 14,750).
The aircraft commander had flown a satisfactory flight the day before with the copilot who, in the past, had experienced difficulty with practice autorotations and lacked experience in the aircraft.
The simulator will enable pilots to practice challenging procedures, without risk, such as low-level flight, confined area operations, autorotations and landing on platforms at sea.
