  advise ATC if a specific clearance will cause undue hazards to persons or property. b. Controllers normally limit ATC ground service and instruction to movement areas; therefore, operations from nonmovement areas are conducted at pilot discretion and should be based ... personnel must be recognized by the pilot, and action should be taken as necessary to avoid such hazards. Taxi, hover taxi, and air taxi operations are considered to be ground movements. Helicopters conducting such operations are expected to adhere…

  Turn Coordinator The gimbal in the turn coordinator is canted; therefore, its gyro can sense both rate of roll and rate of turn. Since turn coordinators are more prevalent in training aircraft, this discussion concentrates on that instrument. When rolling ... into or out of a turn, the miniature aircraft banks in the direction the aircraft is rolled.

Altitude of the hover will vary based on the purpose of the check. HOVER TAXI- Used to describe a helicopter/VTOL aircraft movement conducted above the surface and in ground effect at airspeeds less than approximately 20 knots. The actual height may vary, and some helicopters may require hover taxi above 25 feet…
