Relationship of PIO during landing with Onspeed AOA

[vitlyluvi]

Dear Sir,

I have heard that by following Onspeed AOA technique (constant AOA /Speed) on approach to landing, one gets protection to a large extent from PIO events during landing.

Could some explanation be provided. Does Onspeed AOA technique offer advantage over Reducing Speed / Increasing AOA approaches???

Thanks. Gp Capt LK Vitly. IAF. India.
