 Section 4 - Operational Limitations 

4.1

 

Operational Limitations 

 

The following operational limitations apply: 

 

Geographic limitation:  None 

 

Magnetic field sensitivity:  None 

 

Lightning direct effects sensitivity:  None 

 

Lightning indirect effects sensitivity:  Approved for catastrophic functions 

 

HIRF Susceptibility:  Approved for catastrophic functions 

 

Viewing Angle Limitations:  60° Left / Right, 45° Up / Down 
 

 

Displayable Vspeeds: Vne, Vno, Vfe, Vs1, Vso (Vmc, Vyse ME Only) 

 

Maximum displayable airspeed: 400 Knots / 460 Mph 

 

Minimum displayable airspeed: 30 Knots / 30 Mph 

 

Maximum displayable vertical speed range: -5,000 to 5,000 Feet/Min 

 

Minimum displayable vertical speed range: -100 to 100 Feet/Min 

 

Maximum displayable altitude:  35,000 Feet 

 

Minimum displayable altitude:  -1,500 Feet 

 

Maximum configurable baro correction: 1050 mb / 31.00 inHg 

 

Minimum configurable baro correction: 948 mb / 28.00 inHg 

 

Minimum operational duration on battery: 30 Minutes 

 

Maximum roll rate:  400 degrees / second 

 

Maximum operating G force: 6 G 
 

 

Battery operation may be inhibited for up to 15 minutes during cold-starts. 

 

No operational capability on internal battery is possible if the battery is faulted, as 
shown by a Red-X over the battery icon. 

 

Battery charging is disabled below approximately 0°C and above 40°C, or when power 
input is below approximately 11 volts DC.  

 

In-Flight alignment must be performed with wings-level non-accelerated flight 
conditions. 

 

Airspeed and altitude are derived from internal pressure sensors that are connected to the 
aircraft’s pitot and static lines.  Airspeed is determined by the pressure difference 
between the pitot and static ports, while altitude is determined by the pressure on the 
static port.  Altitude is barometrically corrected by the pilot entered baro value prior to 
being displayed. 

 

Attitude is aided by airspeed to provide better pitch performance during takeoffs and in-
flight accelerations and decelerations.  TSO performance levels are maintained with or 
without this additional aiding.
