Caro ra4000
In merito a quanto da te asserito nel tuo intervento #23, ecco quanto mi rispondono dagli States:
"Hello Romano, Thanks for contacting AOPA's Pilot Information Center. In general, each piece of pavement is considered to be two runways for FAA's purposes of navigational facilities."
Perņ:
"I do not have a specific piece of regulatory guidance that describes this."
Saluti
Romano
