## Normal Procedures (Section 4) 

The normal procedures section is the section most frequently used. It usually begins with a listing of airspeeds that may enhance the safety of normal operations. It is a good idea to learn the airspeeds that are used for normal flight operations. The next part of the section includes several checklists, which cover the preflight inspection, before- starting procedure, how to start the engine, rotor engagement, ground checks, takeoff, approach, landing, and shutdown. Some manufacturers also include the procedures for practice autorotations. To avoid skipping an important step, always use a checklist when one is available. More information on maneuvers can be found in Chapter 9, Basic Flight Maneuvers, and Chapter 10, Advanced Flight Maneuvers. 

## Performance (Section 5) 

The performance section contains all the information required by the regulations and any additional performance information the manufacturer determines may enhance a pilot’s ability to operate the helicopter safely. Although the performance section is not in the limitation section and is therefore not a limitation, operation outside or beyond the flight-tested and documented performance section can be expensive, slightly hazardous, or outright dangerous to life and property. If the helicopter is certificated under 14 CFR part 29, then the performance section may very well be a restrictive limitation. In any event, a pilot should determine the performance available and plan to stay within those parameters. 

These charts, graphs, and tables vary in style, but all contain the same basic information. Some examples of the performance information that can be found in most flight manuals include a calibrated versus indicated airspeed conversion graph, hovering ceiling versus gross weight charts, and a height- velocity diagram.  [Figure 5-7]  For information on how to use the charts, graphs, and tables, refer to Chapter 7, Helicopter Performance. 

## Weight and Balance (Section 6) 

The weight and balance section should contain all the information required by the FAA that is necessary to calculate weight and balance. To help compute the proper data, most manufacturers include sample problems. Weight and balance is detailed in Chapter 6, Weight and Balance. 

## Aircraft and Systems Description (Section 7) 

The aircraft and systems description section is an excellent place to study all the systems found on an aircraft. The manufacturers should describe the systems in a manner that is understandable to most pilots. For larger, more complex

helicopters, the manufacturer may assume a higher degree of knowledge. For more information on helicopter systems, refer to Chapter 4, Helicopter Components, Sections, and Systems. 

## Handling, Servicing, and Maintenance (Section 8) 

The handling, servicing, and maintenance section describes the maintenance and inspections recommended by the manufacturer, as well as those required by the regulations, and airworthiness directive (AD) compliance procedures. There are also suggestions on how the pilot/operator can ensure that the work is done properly. 

This section also describes preventative maintenance that may be accomplished by certificated pilots, as well as the manufacturer’s recommended ground handling procedures, including considerations for hangaring, tie down, and general storage procedures for the helicopter.
