PRACTICE, ETC., WHICH IF NOT
STRICTLY OBSERVED, COULD
RESULT IN DAMAGE TO OR
DESTRUCTION OF EQUIPMENT.
NOTE
An operating procedure,
condition, etc., which is essential
to highlight.
USE OFPROCEDURAL WORDS
The concept of procedural word usage and
intended meaning which has been adhered

Maximum internal approved gross weight
for takeoff and landing is 4,150 pounds
(1882.4 kilograms).
Minimum combined crew weight at
fuselage station 65.0 is 170 pounds (77.1
kilograms) when operating in accordance
with the SELECTIVE PASSENGER
LOADING placard.
1-8. CENTER OF GRAVITY -
LONGITUDINAL
For gross weight longitudinal center of
gravity limits, refer to figure l-l.
The standard helicopter [standard seating
and fuel system) is ballasted in
accordance with the Weight Empty Center
of Gravity chart in the maintenance
manual. The SELECTIVE PASSENGER
LOADING placard shall be installed and
may be used for loading passengers only
within appropriate weight limitations
without computing center of gravity. When
passengers are seated other than in
accordance with the selective loading
placard or the baggage compartment is
utilized, the pilot is responsible for
determining weight and balance to ensure
gross weight and center of gravity will
remain within limits throughout each flight.
The helicopter with nonstandard fuel
system or seating arrangement is not
ballasted in accordance with the Weight
Empty Center of Gravity chart in the
maintenance manual. Selective passenger
loading does not apply and the
ALTERNATE placard shall be installed. The
pilot is responsible for determining weight
and balance to ensure gross weight and
center of gravity will remain within limits
throughout each flight.
Refer to BHT-206L3-MD-1 for loading
tables and instructions.
1-9. CENTER OF GRAVITY -
LATERAL
Lateral center of gravity limits are 4.0
inches (102 mm) left of and 3.5 inches (89
mm) right of fuselage centerline.
1-4 Rev. 4
1-10. DOOR(S) OFF
Determine weight change after doors have
been removed and adjust ballast if
necessary. Refer to BHT-206L3-MD-1.
1-11. AIRSPEED
Basic V,, is 130 KIAS (150 MPH) sea level
to 3,000 feet density altitude. Decrease V,,
for ambient conditions in accordance with
AIRSPEED LIMITATIONS placard (figure 1-
2).
Vne is 84 KIAS (96 MPH) at 85 to 100%
TORQUE takeoff power.
Vne, is 90 KIAS (104 MPH) with any door(s)
off, not to exceed placarded Vne.
1-12. ALTITUDE
Maximum operating pressure altitude is
20,000 feet.
NOTE
For high altitude pressure
operation, refer to appropriate
rules for oxygen requirements.
1-13. AMBIENT AIR
TEMPERATURE
The maximum sea level ambient air
temperature for operation is +51.7°C
(+125°F) and decreases with pressure
altitude at the standard lapse rate of 2°C
(3.6°F)/1000 feet to 20,000 feet.
1-14. MANEUVERING
Aerobatic maneuvers are prohibited.
