Hello everyone!
Quick question on the B1900. What are those fin-like structures that extend downwards and outwards from the rear part of the fuselage? What are they called? What purpose do they serve? (keel effect?) I saw them also on several bizjets but never bothered asking one of the pilots what they were for. (I felt stupid asking the question
)
Also, what are those fin-like structures that extend straight down from the horitontal stab of the B1900? What are they called? do they serve the same purpose of the fins that extend from the fuselage? Is the B1900 the only aircraft that has them? (if so, why?)
While we're on topic, I recently flew on an MD80, and i noticed a small thin and long fin that sticks out from the fuselage into the airstream about 1.5 meters below the rearmost cockpit window (just rear of the AOA probe). What is it? Is it there to provide an aerodynamic effect, or to provide sensor informatin for certain instruments?
Thank you in advance for your answers
