Description:
~ can begin from just about any combination of airspeed and altitude
~ is typically practiced from around 25 feet AGL and 40 knots = 74 km/h
~ can be broken down into 3 parts: the flare, the deceleration, an the approach to a hover

Flare
~ to begin the maneuver the pilot flares the helicopter by pitching the nose up with aft cyclic
~ flare would normally cause the helicopter to gain altitude,
~ but in this case the pilot reduces collective to prevent a climb from occuring
~ power decrease will require right pedal to be applied as well
~ pilot can adjust how quickly the helicopter will decelerate by how aggresively he flares
~ the more aggresive the flare, the faster the helicopter will stop
~ too agressive a flare will cause a tach needle split, in which case
~ rotor will spin faster than the powerplant, and this is generally not the way the maneuver is flown,
~ although nothing harmful will result from this

Deceleration
~ helicopter will decelerate as the pilot holds the flare
~ because the airspeed is decreasing, the flare will immediately start to lose energy, and the helicopter will try to settle
~ instead of allowing the helicopter to settle, the pilot can increase the flare
~ this will maintain altitude, and cause the helicopter to decelerate even faster
~ there is an upper limit to how much the pilot should flare the helicopter
~ deceleration becomes so fast it is more difficult to judge, plus the helicopter ends up in an extremely tail low attitude
~ instead of continueing to pitch the nose up, the pilot can start adding power to maintain altitude
~ he does this by raising collective
~ this not only maintains altitude, but it maintains rotor thrust and keeps the helicopter decelerating quickly
~ pilot should continue to hold altitude and attitude until he is about to lose ETL (effective translational lift)

Approach_To_Hover
~ before ETL is lost, pilot pitches the nose of the helicopter back down into an approach attitude using forward cyclic
~ attitude is still slightly nose high, as on a normal approach, but is not in a flared attitude
~ pilot can simply look ahead of the helicopter and pick a spot aligned with a 10 degree approach angle
~ he then flies a normal approach to the spot
