1/You make a vertical approach but you are :
heavy
down wind
low speed , nearly zero..
High rate of descent...
You are in good conditions to going to VRS...but not sure at 100% Sometimes nothing happens...
2/From the edge of the Grand canyon, you go in hovering just at the power limit nearly 95 %... you translates slowly to te grand Canyon....When you arrive above the Grand Canyon, you lose the IGE and you falling down : That is Settling with power and sure at 100% it's happens all the time..
The really one difference is , you need much more power in OGE than IGE....no matter with thewind, yourspeed or your rate of descent asYour are hovering..but VRS is aerodynamic and SWP is justa power matter.. and exactly 7%...No more, no less
