ACI 2 (Mod 4&5 - Finals) Flashcards
Inventor of black box
David Warren
When was the invention of black box
1953
When was the production of black box
1957
Parameters recorded by Flight Data Recorder
- Time
- Pressure Altitude
- Airspeed
- Vertical Acceleration
- Magnetic heading
- Control-column position
- Rubber-pedal position
- Control-wheel position
- Horizontal stabilizer
- Fuel flow
How many microphones are connected in the plane’s cockpit
4
Any sounds in the cockpit are picked up by these microphones and sent here, where the recordings are digitized and stored.
Cockpit voice recorder
provides pre-amplification for audio going to the cockpit voice recorder
associated control unit
Location of the four microphones
- Pilot’s headset
- Co-pilot’s headset
- headset of a third crew member
- Near the center of the cockpit
Where is the FDR & CVR located
back of the plane
two technologies used for recording and storage
- magnetic tape
- solid-state technology
What tape is used in magnetic tape
Mylar tape
When was magnetic tape first introduced
1960s
uses stacked arrays of memory chips, so they don’t have moving parts
solid-state recorder
Data from both the CVR and FDR is stacked in memory boards inside the
crash-survivable memory unit(CSMU)
test that make up the crash-survival sequence
- crash impact
- pin drop static crush
- fire test
- deep-sea submersion
- fluid immersion
- salt-water submersion
how many parameters can a magnetic tape track
100
how many parameters can a solid-state recorder track
700 or more
All the data collected by the airplane’s sensor is sent to the
flight-data acquisition unit (FDAU) at the front of the aircraft
middle manager of the entire data-recorder process
Flight-data acquisition unit (FDAU)
Black boxes are powered by one of two power generator
- 28V DC power supply
- 115V, 400Hz AC power supply
Each recorder is equipped with a third essential black box tool,
called the
Underwater Locator Beacon (ULB)
When the recorder is immersed in water this device is activated
pinger
The pinger can transmit from depths down to
14,000 ft
Once the beacon begins “pinging,” it does so
once per second for 30 days
Following an accident, both recorders are removed from the accident site immediately and transported to the computer labs at the
NTSB headquarters in Washington, D.C
Significance of black box
- Accident investigation
- Performance monitoring
- Compliance
- Training
- Safety enhancement
If mp3 were integrated to future black boxes how many hours would it be capable of recording
500 hrs
a set of standards that reduce the vertical separation between aircraft flying at high altitudes.
Reduced Vertical Separation Minimum (RVSM)
RVSM allows aircraft to fly with only
1,000 feet of vertical separation
All aircraft operators intending to fly within RVSM applied Flight
Levels (FLs) are required to be registered with the
JASMA
Reduced Vertical Separation Minimum (RVSM) was introduced to reduce the vertical separation above flight level (FL
290
Flight levels that were added
FL290 to FL410
has responsibility for the provision of monitoring and safety assessment activities in Fukuoka FIR, and maintain a database of RVSM approval aircraft.
JASMA
Benefits of RVSM
- Increased airspace capacity
- Fuel efficiency
- Reduced congestion
- Environment impact
RVSM requirements in terms of equipments
- Precise altimeters
- Autopilots
- Altitude alerting systems
- Mode C/S transponders
RVSM requirements in terms of certification
RVSM approval
RVSM requirements in terms of maintenance
Regular maintenance and calibration
