One big reason is to make room for external stores such as fuel, weapons and electronics packs. A low-wing design must have longer and therefore heavier and bulkier undercarriage if ground access to the underwing hard points is to be adequate. Also, the upper surface of a high wing is larger and cleaner, providing better lift over the fuselage and reducing ...

Fin and Tail formation lights. Look up slime lights. When lit, they look like slimy green, hence the name. They are used for flying formation at night when it isn't possible to use visual clues such as wingtips, missiles, intakes, etc. Basically for dark/night visual pickup, formation keeping. They are for night operations and have visible and infrared ...

Trapezoidal wings have advantages and disadvantages: Better performance than delta wings at transonic speed Good stealth performances Flaps can be easily used. drag reducing better Lift/Drag ratio than delta wings The problem is that they stall at much lower angles of attack than delta wings. Edit:this problem is overcome using leading edge,LERX,and/or ...

the reason for two vertical tails is so the plane can maneuver during high angle of attack situations. With a single vertical tail, you cannot turn ( maneuver ) during a high angle of attack situation, making the plane a strafing target.

An unsung property of winglets is that they improve yaw stability, which can actually reduce drag, especially for designs which require yaw damping. Going back to the days of the Sopwith Camel, fighters benefit from instability to turn more effectively. While today's fighters have computers to make them safer, the Camel was very challenging to fly. ...
