Weeping wing
Deicing systems pump fluid from a reservoir through a mesh screen embedded in the leading edges of the wings and tail. depend on airflow as well, and if the primary air intake ices, an alternate air door either opens automatically
Tail Stall
The horizontal stabilizer balances the tendency of the nose to pitch down by generating downward lift on the tail of the aircraft. When the tail stalls, this downward force is lessened or removed, and the nose of the airplane can severely pitch down.
Induction System Ice
Not all aircraft ice is structural; induction icing is the cause of many accidents.
Deicing
Is used after ice has built up to an appreciable amount. Typically this includes surface deice equipment.
Cloud tops
You cannot climb through a front with tops to 30,000 feet. For most light nonturbocharged aircraft, once the tops reach 8,000 feet, climbing is no longer an option.
Autokinesis
At night, a stationary dim light against a dark background will appear to move if a pilot visually fixates on the light for about six to 12 seconds.
Nondirectional Radio Beacon (Ndb)
An L/MF or UHF radio beacon transmitting nondirectional signals whereby the pilot of an aircraft equipped with direction finding equipment can determine the bearing to or from the radio beacon and “home” on or track to or from the station.
Anti-icing
Is turned on before the flight enters icing conditions. Typically this includes carburetor heat, prop heat, pitot eat, fuel vent heat, windshield heat, and fluid surface deicers (in some cases). Then when the boots deflate, a “bridge” of ice remains that cannot be shed during the next inflation cycle. Although some residual ice may remain after a boot
VASI
Visual approach slope indicators provides visual descent guidance during the approach to a runway. The
lights are arranged in bars and vary in number from two to 16.
