2.1. Introduction
The Chapter 2 contains operational limits necessary for safe operation of the aircraft.
2.2. Air Speed (CAS)
Never exceed speed vNE 136,1 kt (145,2 kt IAS)
Do not exceed this speed in any case!
Design manoeuvre speed vA 90,0 kt (93,6 kt IAS)
After exceeding this speed, do not use full deflection of any control surfaces and do not make any
sudden control operations. An overload of the aircraft may occur!
Maximum design cruising speed vC 108 kt ( 114 kt IAS)
Do not exceed this speed except the flight in smooth air, but with caution!
Max. cruising speed at severe turbulence vRA 108 kt (114 kt IAS)
Do not exceed this speed at severe turbulence!
CAS IAS
Max. speed, flaps deflected to I. (10 °)
FE,I
70 kt 71,1 kt
Max. speed, flaps deflected to II. (20 °)
FE,II
65 kt 65,5 kt
Max. speed, flaps deflected to III. (35 °)
FE,III
60 kt 59,8 kt
Recommended speed, flaps deflected to III. VFE 50 kt 48,6 kt
Never exceed these speed limits when flaps deflected!
Stall speed, flaps retracted vS1 45,0 kt 42,7 kt IAS
Flying this speed and with flaps retracted results in loss of lifting force and fall of the aircraft!
Stall speed in landing configuration vSO 35,8 kt 32,8 kt IAS
Flying this speed with flaps deflected at the position III. results in loss of lifting force
and fall of the aircraft!
