Re: 412 Doors open VNE
1. Check the flight manual in the first instance regards the model type etc.
2. The type of seating installed (cushions!), as mentioned earlier will determine if you can fly/open them at all.
Use 60Kts maximum door opening and closing speed.
I have a feeling that the flight manual states the following;
80kts Asymmetrical open door(latched)
100kts Symmetrical open door (latched)
