Aero and Hydro, Vol 5, Nov 2, 1912, 80-81, "Aviation Instruments: Construction and Use, I. Altitude" E. R. Armstrong
If you do not have the technical expertise to engineer, build, or fly the aircraft then what I have to say next does not matter.
The Motivation:The Motivation:
In a five year span from September 1989 to September 1994 my airline experienced five major airline accidents resulting from:
A Rejected Take-off: A Rejected Take-off: 20 September 1989; 737-20 September 1989; 737-400; La Guardia Airport, 400; La Guardia Airport, New York: New York:
The crew of flight 5050 rejected takeoff due to rudder trim problems. The aircraft overran the runway and was partially submerged in water. Two of the 55 passengers were killed.
Flight 1493 was cleared to land on a runway which also had a Metroliner III on the runway awaiting takeoff. The aircraft collided and burst into flames. Two of the six crew members and 20 of the 83 passengers on the jet were killed. All 10 passengers and 2 crew members on the Metro III were killed.
Deicing: 22 March 1992; F28-4000; New York, NY:
On flight 405 the aircraft crashed just after takeoff in snowy conditions due to icing on the aircraft's wings. Three of the four crew members and 24 of the 47 passengers were killed.
Wind Shear: 2 July 1994; DC9-31; Charlotte, NC:
On Flight 1016 the aircraft encountered On Flight 1016 the aircraft encountered heavy rain and wind shear during heavy rain and wind shear during approach at about 3.5 miles (5.6 km) approach at about 3.5 miles (5.6 km) from the runway. The crew executed a from the runway. The crew executed a go around for another landing attempt, go around for another landing attempt, but the aircraft could not overcome the but the aircraft could not overcome the wind shear. All five crew members wind shear. All five crew members survived, but 37 of the 52 passengers survived, but 37 of the 52 passengers were killed.were killed.
Rudder Upset:Rudder Upset: 8 September 1994; 737-300; 8 September 1994; 737-300; near Pittsburgh, PA:near Pittsburgh, PA:
On flight 427 the aircraft lost control at about 6,000 feet (1830 meters) during approach. All five crew members and 127 passengers were killed.
Individually these accidents were not in and of themselves directly related to operations and could have occurred at any airline.
