Limitations of high-speed flight
If there are any indications that an airspeed limit may be exceeded (e.g.
when flying in wave rotors, near thunderstorms or other turbulent
conditions), extend the airbrakes carefully before exceeding 200 km/h /
108 kts). In emergencies the airbrakes may be extended up to V
NE,
as
defined in Section 2.2. Above 250 km/h / 135 kts the airbrakes are
sucked open after unlocking, resulting in a significant deceleration which
may result in pilot induced oscillations (P.I.O.). This effect is least in the
negative flap position. When the airbrakes are extended in possible
turbulent conditions the Rough Airspeed (V
RA
) should not be exceeded.
Decelerate to 200 km/h / 108 kts before closing the airbrakes. The forces
acting on the airbrakes at speeds above 220 km/h / 118 kts are very high.
WARNING:
Although the airbrake damper reduces the deceleration
associated with the opening of the airbrakes at high
speeds,
the negative G’s may still result in the pilot’s
head shattering the canopy if the seat harness straps
are not tight. Ensure that the seat harness straps are
tight before operating the airbrakes at high speeds.
Altitude limitations
The aircraft is limited to an altitude of 9000 m or 30000 ft Above Mean
Sea Level (AMSL).
See Section 4.5.8 for more details.
