5. MAXIMUM SPEED
5.1 VNE with doors closed
5.1.1 VNE Power–on
Definition
- Absolute VNE is 155 kt (287 km/h – 178 MPH) at zero pressure-altitude.
- At higher altitudes this speed is to be reduced by 3 kt (5.5 km/h or 3.5 MPH) per
1000 ft or 18 km/h per 1000 m.
- In cold weather the following must be subtracted from VNE:
10 kt (19 km/h – 12 MPH) when OAT is below -30°c.
Term
VNE Power-off
Definition
- Absolute VNE is 125 kt (231 km/h – 144 MPH) at zero pressure-altitude.
- At higher altitudes this speed is to be reduced by 3 kt (5.5 km/h or 3.5 MPH) per
1000 ft or 18 km/h per 1000 m.
- In cold weather the following must be subtracted from VNE:
10 kt (19 km/h – 12 MPH) when OAT is below -30°c.
Term
VNE with doors open or removed
Definition
5.2.1 Aircraft fitted with four standard doors (LH and RH hand doors)
VNE is limited to 70 knots (130 km/h – 81 PMH) for the following permissible
configurations:

Flight in falling snow
Definition
- Flight when visibility is greater than 1500 m (0.81 NM): flight in falling snow is
authorized.
