Pilot Aircraft is the skill of operating and navigating aircraft, requiring understanding of aviation principles and flight mechanics. Piloting is difficult and you need training to perform even standard actions like take-off or landing.
Roll d100 + your Piloting skill against DR 100
On a successful roll you can fly helicopters, hot air balloons or even war planes. A roll is usually required in any non-standard situation.
+30 DR when attempting to fly alien vessels (different from the technology of your time period or civilisation)
+20 DR when flying in difficult (weather) conditions
+20 DR to perform exceptional maneuvers like loops or battle actions
-20 DR in a familiar aircraft
While fleeing from your crashed spaceship - being chased by a group of enraged musketeers (early modern civilisation stage) - you stumble upon a zeppeliner port. You attempt to fly the unfamiliar aircraft to escape your pursuers. Roll Pilot Aircraft against DR 120, since you are on a "alien" aircraft, but the DM rules it is fairly simple granting you a smaller penalty of 20 than the standard 30.
While flying a war plane above a battlefield you attempt to dodge an earth-to-air missile launched from a bazooka. Roll against DR 120 (battle action) to succeed.
With this skill you are a trained pilot. You know how to fly any type of aircraft occuring in your culture or setting. Unfamiliar types of aircraft may pose challenges, but you have a fair chance to pilot even alien or unfamiliar vessels.
Pilot Aircraft allows you to fly and navigate anything from hot-air balloons to futuristic anti-gravity scooters.
Can be sequenced with the Captain skill on large aircraft.
Not normally countered, but could be countered by Sabotage or similar skills.
