AIRSPEED LIMITATIONS
Maximum Operating Speed
V
MO
..............................................280 KIAS (Ventral fuel tank not empty, Flaps 0
°
)
V
MO
..............................................335 KIAS (Ventral fuel tank empty, Flaps 0
°
)
Sea Level to 12,000 ft, reducing by 1 kt per 680 ft
to 310 KIAS at 29,000 ft.
Maximum Operating Mach Number
M
MO
.............................................0.80 IMN
M
MO
.............................................0.73 IMN with Mach Trim System Fail/Inoperative and
Autopilot disengaged.
NOTE: The maximum operating speeds and operating Mach numbers as given above
shall not be deliberately exceeded in any regime of flight (climb, cruise or
descent) except for the purpose of pilot training or routine test flights in
accordance with Section 5, Sub-section 2 of the Pilot’s Operating Manual (POM).
If the limits are inadvertently exceeded, speed shall be reduced to or below the
limiting values as quickly as possible.
Maneuvering Speed
V
A
.................................................196 KIAS
NOTE: Maneuvering speed is the speed below which full application of aerodynamic
controls will not result in excessive airplane loads. Maneuvers involving angles of
attack near the stall should be confined to speeds below V
A
.
Avoid rapid and large alternating control inputs, especially in combination with
large changes in pitch, roll or yaw (e.g. large slip angles) as they may result in
structural failures at any speed, including below V
A
.
Wing Flaps Extended/Operating Speed
V
FE
/V
FO
.......................................220 KIAS (Flaps 15
°
)
175 KIAS (Flaps 25
°
)
165 KIAS (Flaps 45
°
)
Procedural Use of Flaps 15° for Descent and Holding
The maximum airspeed for procedural use of flaps 15
°
for descent and holding is 220 KIAS.
The maximum altitude for use is 15,000 ft. Such use of wing flaps is not permitted in icing
conditions.
