Despegue,
There's no data quoted in the POH for a 10° flap setting so I'm interested to know from where you can extrapolate performance figures for this type of operation. Plus, you're using a higher Vr than quoted for a normal TO and so, with the extra drag of 10° flap, the effect would be to LENGTHEN the take-off run.
I'd also be very interested to know who doesn't recommend normal TO procedures in Spain and why; I've flown there in my Arrow a few times and never had a problem.
