FLIGHT MANUAL BK117 C-1 EUROCOPTER 4 - 1 LBA APPROVED Rev. 6 S E C T I O N 4 N O R M A L P R O C E D U R E S 4.1 GENERAL This Section contains instructions and recommended procedures which are peculiar to the operation of this helicopter. For definition of terms, abbreviations and symbols used in this Section refer to Section 1. 4.2 PREPARATION FOR FLIGHT 4.2.1 Flight Restrictions The minimum, normal, maximum and cautionary operation ranges for the helicopter and its subsystems are indicated by instrument markings, placards and decals. For helicopter and subsystem restrictions refer to Section 2, Limitations. NOTE Before helicopter operation with a passenger on copilot’s seat, cyclic stick and collective pitch lever on copilot’s side should be removed, copilot’s pedals adjusted to the most forward position and the dual control covers (see FMS 10-16) installed. If the covers are not available, cyclic and collective levers shall remain installed. However, in this case, the passenger must be briefed properly before starting engines not to interfere with any pilot’s control operation. 4.2.2 Flight Planning Refer to Sections 5 and 9 to determine required fuel, airspeeds and power settings for takeoff, climb, cruise, hovering and landing data necessary to accomplish the mission. NOTE Before flight it is necessary to check that the fuel grade is selected properly relative to fuel temperature/altitude limitations given in section 2. 4.2.3 Mass and Balance The takeoff and anticipated landing gross mass and balance should be obtained before takeoff and checked against mass and load limits and center of gravity restrictions (see Section 2). FLIGHT MANUAL BK117 C-1 EUROCOPTER 4 - 2 LBA APPROVED Rev. 6 4.3 PREFLIGHT CHECK 4.3.1 General The preflight check shall be accomplished, according to either the Flight Manual, the Maintenance Manual or the Pilot’s Checklist. The preflight check is not a detailed mechanical inspection, but essentially a visual check of the helicopter for correct condition. This check shall be completed before each flight. However, items not marked with a star (L) need only be checked before the first flight of the day. When unusual local conditions dictate, the extent and/or frequency of this check shall be increased as necessary to promote safe operation. NOTE D The following list contains only check items for the standard configuration. D In addition to these items, check antennas and all installed optional equipment. D Make certain that all relevant intermediate and special inspections in accordance with the Maintenance Manual have been complied with. D For optional equipment check items, refer to the respective Flight Manual Supplement or Maintenance Manual, Chapter 800. FLIGHT MANUAL BK117 C-1 EUROCOPTER 4 - 3 LBA APPROVED Rev. 6 4.3.2 Exterior Check The exterior check is laid out as a walk-around check, starting forward right at the pilot’s door, proceeding clockwise to the tail boom, to the left hand side (including the upper and lower areas of the helicopter) and is completed at the helicopter nose area. NOTE D If possible, the helicopter should be headed into wind before starting the engines. D The area around the helicopter should be clear of all foreign objects. D To avoid excessive drain on the helicopter battery, particularly during cold weather, all ground operations should be conducted using an external power unit (EPU). D When the battery is used, the operation of electrical equipment should be kept to a minimum. 1. Fuselage - Right side 2. Cabin - Top 3. Tail boom - Aft area 4. Fuselage - Left side 5.

Blade strike should be suspected if unusual noise or bang was audible during runup. Under gusty or turbulent wind conditions, especially with vertical wind components, and low rotor rpm (below 25%) main rotor blade(s) may strike the vertical stabilizer(s) - MAINTENANCE ACTION!
