NICE VIEW!
Airline Pilots Controlled by Automated Technology
FAA Draft on Pilots related to Technologies
Presenter: Roy Li
FACTS
More radiation than nuclear plant workers
ICRP andFAA consider them as the occupational radiation workers.
average basis are getting 1.6
people who fly in airplanes who are getting 2 or 3 or 4 milliSieverts per year
Growing Issue
NASA first investigated the issue on cosmic radiation in 1960s and 1970s.
had little concern on human health impacts
potential damage to communication and navigation technology

3 Principal factors
1. Altitude: the higher you go, the greater the dose

2. Latitude: the closer you get to the poles, the greater the does

3. Hours of Flight: the longer you fly, the greater the dose
Less protection from cosmic radiation at the typical cruising altitudes
between 7000 and 12000 metres.
Cosmic radiation doubles every 2000 meter increase
Altitude
Health Concerns
Damage to Cells
prenatal exposure
genetic defects
cataracts
cancer
Protection
Sources
FAA has released a draft of study focusing on airline pilots rely on automation technology.

"abdicate too much responsibility to automated systems" resulting in significantly weaker flying skills
AUTOPILOT
Discourage or prohibit to turn off aircraft's autopilot.
Rory Kay, FAA advisory committee on pilot training
"Airline industry is suffering from 'automation addiction' "
46 accidents and major incidents, voluntary reports by pilots as well as data from more than 9000 flight
Radiation
The international unit of radiation dose is called the sievert (Sv).
millisievert (1000 mSv = 1 Sv)
What is Cosmic Radiation?
Radiation coming from outside the solar system
Cosmic radiation from solar flares
Issue
FL 390 60x greater
FL 510 200x greater
FAA states, an airline crewmember flying 1,000 block-hours annually at FL350 receive 5 mSv per year.
0.02 mSv is equivalent to 1 chest x-ray
250 Chest X-rays
Air Canada
low incidence of cancer
healthier lifestyle than non-pilots

myeloid leukemia
astrocytoma
malignant melanoma
Three Types of Cancer found in Pilots
Wear a dosimeter
Estimate exposure
Eat Vegetables and Fruits

Latitude
Polar Routes
Hours of Flight
Atmosphere thinnest near the earth's north and south poles. =exposed to more radiation
Typical polar flight=two chest X-rays
exposure rate is 3-5 times higher
shortest way
fuel efficient: save $40,000 per flight
the number of flights over polar routes increased
MOS 1022 F
60%
of accidents and
30%
major incidents were caused by pilots
having trouble flying manually
making mistakes with automated flight controls
February 12th, 2009
Colgan Air Flight (Continental Connection)3407
Newark, New Jersey to Buffalo, New York
Co-pilot programmed incorrect information into the computer and fail to respond properly to the stall warning. The aircraft crashed killing all 49 people aboard and one on the ground.
Small incidents include pilots spending time to restart autopilot or other automated systems.

Grasp the controls and fly the airplane!
Best ways to handle this situation
Change of policies
Airline company can change their automated requirement.
1. Educate and encourage pilot to climb levels manually after takeoff. (example, climbing to about 18,000 feet before turning on the autopilot)

2. Encourage pilots to turn off autopilot when dealing with significant amount of turbulence.
Full-motion stimulation
Airline company can take over fixed base simulators and paper mock-up for line check
Having the physical experience helps pilots to feel more comfortable in a real emergency.

Hypersonic speed?
-Supersonic is when the rate of travel exceeds the speed of sound (mach 1)
-Hypersonic is over mach 5
-Very difficult to attain, since it requires new type of engines that can provide thrust over the 2.5 mach speed
-Also need to consider comprehensively of aerodynamics and aero thermal effects at travelling at hypersonic speeds
Scramjet engine
Conventional jet engines have the top speed of mach 2.5
Scramjet engine can only function above mach 3
This leaves the gap of 0.5mach.
This gap will be made up by modified fighter jet engine technology

-This is an immense technological advancement. In order to travel hypersonic speed, the machine has t o overcome the incredible heat
- “Typical, temperatures in [scramjet] engine exceeds over 1000°C; [which is] much higher than the melting point of many conventional materials.” (2013, J. Dupont)
-Furthermore at the speed of Mach 6 the jet can reach "any location across a continent in less than an hour".(2013, B. Leland)

Significance
This technology can create many controversies due to the potential weaponry usage; however this development will certainly allow for advancement in technology.

In Conclusion,
Different pilots have different flying styles, however automated technology should not control how a pilot flies.
-Successor of SR-71 black bird
-SR-72 is the plane in production that will be the first to reach hypersonic speed.
-Estimated top speed of Mach 6, just over 7000kph
-Developed by Lockheed
-Production estimated at 2030

SR-72
Thank You!

Usages of this technology

-Spying
-Combat attack (weapon)
-Future technologies for transportation
-Cheaper way to excess space (especially from a conventional runway
