Hello,

New to this site. Just checking to see if anyone can help me:

Is there some rule that states that turbine jet aircraft, when operated on commercial passenger flights, need to use a factor of 1.67 to calculate the Required landing airfield length (ie Landing distance required as per aircraft Flight manual x 1.67 = Required Landing runway length)?

We are studying the possibility of setting up an air taxi in India with VLJs. And just received news that - No problem when these aircraft operate as "private flights" to the shorter airfields in India. The problem is when operated as "commercial flights", we need to multipy the airplane landing distance x 1.67 to arrive at the "required airfield landing length". And when we do this, it exceeds the available runway lenghts in most short airfields.

Apparently this is some standard RPT (regular public transport) operations rule of 1.67 applicable to all aircraft. I am unaware about this and need to know more. If anyone can help, or lead me to some link on this subject, that would be great...

Thanks,
