Section 1LIMITATIONS

1LIMITATIONS

Compliance with Limitations section isrequired by appropriate operating rules.Anytime an operating limitation is exceeded,an appropr iate entry shal l be made inhelicopter logbook. Entry shall state whichlimit was exceeded, duration of time, extremevalue attained, and any additional informationessential in determining maintenance actionrequired.

In ten t iona l use o f t rans ient l imi ts isprohibited.

Turn anti-collision light OFF during flight in ornear visible moisture to prevent reflectionsand possible pilot vertigo. Keep cabin glassclean to prevent halation.

TYPE OF OPERATION

The basic helicopter is approved for five placeseating and is certified for land operationunder day or night VFR non-icing conditions.

Flight operations are approved with thelanding gear crosstube fairings installed orremoved.

NIGHT FLIGHT LIMITATIONS

Night flight operation is limited to visualcontact flight conditions. Orientation shall bemaintained through visual reference toground objects solely as a result of lights onthe ground or adequate celestial illumination.

FLIGHT WITH DOOR(S) OFF

All unsecured items must be removed fromcabin.

Do not exceed Airspeed and Center of GravityLimitations.

Protracted rearward and sideward flightprohibited.

External Cargo Loading limited to 3350pounds (1519.6 kilograms) gross weight withany combination of door(s) OFF.

Flight with forward door(s) OFF is prohibitedwith litters.

FL IGHT WITH OPTIONALEQUIPMENT INSTALLED

The following equipment shall be installedwhen conducting flight operations in fallingand/or blowing snow to reduce possibility ofengine flameout:

The Particle Separator Engine Air InductionSystem Kit (BHT-206B3-FMS-10), Deflector Kit(BHT-206B3-FMS-12), and Engine (Automatic)Re-ignition Kit (BHT-206B3-FMS-18).

Re fer to appropr ia te F l igh t ManualSupplement(s) for additional Limitations,Procedures, and Performance Data.

FLIGHT CREW

The minimum flight crew consists of one pilotwho shall operate the helicopter from theright crew seat.

External — 3350 pounds (1519.5 kg)

FRONT SEAT WEIGHT

Minimum — 170 pounds (77.1 kg)

NOTE

Ballast as required to maintain weight empty CG within limits. Refer to Center of gravity vs Weight Empty chart in BHT-206B3-MM-1.

LONGITUDINAL CENTER OF GRAVITY LIMITS

Center of gravity limits are from station 106.0 (2692.4 mm) to 114.2 (2900.7 mm); however, the aft limits are variable depending upon gross weight. Refer to Center of Gravity vs Gross Weight char t (F igure 1 -1 ) and BHT-206B3-MD-1.

NOTE

Station 0 (datum) is located 55.16 inches (1401.1 mm) forward of forward jack point centerline.

DOOR(S) OFF

No change from basic helicopter CG with only the aft cabin door(s) OFF.

Center of gravity limits are from station 106.0 (2692.4 mm) to 110.0 (2794.0 mm) with one or both forward door(s) OFF or any combination of forward and aft cabin door(s) OFF.

Actual weight change shall be determined after doors, etc., have been removed and ballast readjusted, if necessary, to return empty weight center of gravity to within allowable limits.

LATER CENTER OF GRAVITY LIMITS

3.0 inches (76.2 mm) left of hel icopter centerline.

4.0 inches (101.6 mm) right of helicopter centerline.

NOTE

Lateral CG limits vary depending on longitudinal CG location. Refer to Lateral vs Longitudinal CG Limits chart (Figure 1-2).

POWER PLANT LIMITATIONS

Rolls Royce Model 250-C20B Engine or 250-C20J Engine. The 250-C20B engine limitations contained herein are applicable to the 250-C20J engine.

WARNING

USE OF THE THROTTLE TO CONTROL RPM IS NOT AUTHORIZED. (REFER TO SECTION 3, EMERGENCY AND MALFUNCTION PROCEDURES FOR EXCEPTION.)

POWER ON

Steady-state operation — 75 to 88% N2 and engine torque greater than 33% is prohibited. Trans ient operat ion through range is permissible.

Minimum — 97%

Maximum — 100%

Transient, 15 seconds — 105%

NOTE

Refer to the Rolls Royce Operation and Ma in tenance Manua l for operation in the N2 speed avoidance range and for transient overspeed limits.

CAUTION

IF THE MAIN ROTOR IS NOT ROTATING BY 25% GAS PRODUCER SPEED (N1), ABORT THE START.

Starter — Release at 58% gas producer RPM (N1).

Engine and transmiss ion oi l — Check pressures increasing.

CAUTION

IF THE ENGINE HAS BEEN SHUT DOWN FOR MORE THAN 15 MINUTES, STABILIZE AT IDLE SPEED FOR 1 MINUTE BEFORE INCREASING POWER.

NOTE

During cold temperature operations, stabilize engine at idle speed of 60 to 62% gas producer RPM (N1) until oil temperature reaches a minimum of 0°C.

Gas producer RPM (N1) — Check for 60 to 62%.

External power — Disconnect; BAT On.

Throttle — Open to 70% gas producer RPM.

GEN switch — On.

Throttle — Idle.

WARNING

AVOID CONTINUOUS OPERATION WHEN BETWEEN 75 AND 88% N2 AND ENGINE TORQUE GREATER THAN 33%.

Radio equipment — On.

ELT (if installed) — Check for inadvertent transmission.

POS LT switch — On.

PRELIMINARY HYDRAULICS CHECK

NOTE

Uncommanded control movement or motoring with hydraulic system off may ind icate hydrau l ic sys tem malfunction.

HYDRAULIC SYSTEM or CONTROL BOOST switch — OFF, then ON.

ENGINE RUN-UP CHECK

Smoothly and firmly advance throttle at a cont inuous rate to fu l l open posit ion, maintaining collective pitch down and cyclic control in neutral.
