Communication in Aerospace Management Flashcards
The piston moves away from cylinder head, the intake port opens, fuel/air mixture is drawn in the cylinder.
Intake
The piston moves back toward the cylinder head, intake port close, fuel/air mixture is compressed.
Compression
The spark ignites the compressed fuel/air mixture forcing the piston down the cylinder and revolving the crankshaft
Power/Ignition
As the piston moves towards the cylinder head for the second time, the exhaust port opens, burnt gases are forced out of the cylinder.
Exhaust
abnormally rapid combustion due to low octane grade fuel, too lean fuel/air mixture, high cylinder head temperature
Detonation
Gasoline powered piston is most common propulsion system used in general aviation. Similar to automobile engine but it is lighter burns more highly refuse fuel and is aircooled.
The Reciprocating Engine
Types of Engine
Piston engine and Turbine engine
Turbine engine
Turbo jet – missile, Concorde, jet
Turbo fan – used by commercial aircraft
Turbo props – with propeller
turbo shaft - helicopter
There are three axes about which an aircraft rotates. All three go through the ___
centre of gravity.
The lateral axis generally runs from ___. Remember: L A T – Links Aerofoil Tips.
wingtip to wingtip
The lateral axis generally runs from wingtip to wingtip. The aircraft moves in the ___ plane about this axis.
pitching
The ____ axis runs from nose to tail. Remember: aLONG the length of the aircraft. The aircraft moves in the ___ plane about this axis.
longitudinal, rolling
The ___ axis runs vertically downwards.
The aircraft moves in the ___ plane about this axis.
normal, yawing
VLF – Very Low Frequency
0 – 30 KHz
LF – Low Frequency
30 KHz – 300KHz
MF – Medium Frequency
300KHz – 3,000KHz
HF – High Frequency
3MHz - 30 MHz
VHF – Very High Frequency
30 MHz – 300MHz
UHF – Ultra High Frequency
300-3,000 Mhz
SHF - Super High Frequency
3-30 Ghz
EHF – Extremely High Frequency
30-300 Ghz
similar to DME for military and naval operation
TACAN – (Tact. Air Nav)
similar to VOR/DME but for military use
VORTAC
precision navigation guidance for exact alignment and descend of a/c on approach to runway it provides azimuth, elevation and distance
Microwave Landing System ( MLS )
provide heading, total time to reach station and destination, direction and ground speed
Global Position System (GPS)
use for landing aid rather than sequencing and spacing of a/c It is similar to aninstrument landing system(ILS) but requires control instructions.
Precision Approach Radar ( PAR )
low or med frequency radio beacon transmits non directional signal whose pilot of aircraft can define his bearing and home on the station.
Non Direct Beacon ( NDB )
designed to provide an approaching path for exact alignment and descent of A/C on final approach to runway ILS range up to 20 NM radius.
Instrument Landing System ( ILS )
___ are most commonly used as markers or “locators” for an instrument landing system (ILS) approach or standard approach. a localizer is the lateral component of the instrument landing system (ILS) for the runway centreline when combined with the vertical glide slope, not to be confused with a locator, although both are parts of aviation navigation systems.
NDB
3 parts of ILS
- Guidance info - Localizer , glideslope
- Range info - marker beacon, DME
- Visual info – approach light, touch down, center light, runway light.
If both transmitters and receivers are inoperative what will you do?
Fly Triangular Pattern
Steady Green (ground)
cleared for take off
Steady Green (air)
cleared to land
Flashing Green (ground)
cleared for taxi
Flashing Green ( air)
return to landing position
Steady Red ( ground )
Stop
Steady Red ( air )
Give way
Flashing Red ( ground )
clear the runway
Flashing Red ( air )
do not land
Flashing white
Return to starting point
Alternating Red and Green
Proceed with caution
also called air terminal, aerodrome, or airfield, site and installation for the takeoff and landing of aircraft. An ___ usually has paved runways and maintenance facilities and serves as a terminal for passengers and cargo.
Airport
Is a location where aircraft such as fixed-wing aircraft, helicopter and blimps take off and land. Aircraft may be stored or maintained at an ____
airport
An ____ is consisting of at least one surface such as a runway for a plane to take off and land, and often includes building such as control tower, hangar and terminal building.
airport
include parking lots, public transportation, and access roads.
LANDSIDE AREAS
include all areas accessible to aircraft, including runways, taxiways, and ramps.
AIRSIDE AREAS
Is a strip of land at an airport on which aircraft can take off and land.
____ may be a man-made surface (often asphalt, concrete or a mixture of both) or a natural surface (grass, dirt, gravel or salt).
Runway
Is a path on an airport connecting runways with ramps, hangar, terminals and other facilities. The mostly have hard surface such as asphalt or concrete.
Taxiway
___ is part of an airport. It is usually the area where aircraft are parked, unloaded or loaded, refueled or boarded.
Airport Ramp
Known as a car park in countries such as Malaysia, Australia, United Kingdome and Ireland). Also known as car lot. Is a cleared area that is more or less level and is intended for parking vehicles.
Parking Lot
Comprises passenger transportation services which are available for use by general public as opposed to modes for private use such as automobiles or vehicle for hire
Public Transport
Provides critical links between public use airport facilities and the public roadway network serving the surrounding area. The design and construction of ____ built within airport property boundaries are eligible for federal capital improvement funding and state funding through the Airport Capital Program.
access road
Provides restricted access within airport’s airfield. These roads are used by airport and FAA staff to conduct business activities such as security checks and maintenance work on an airport.
Perimeter Roads
Is a building at an airport where passenger transfer between ground transportation and the facilities that allow them to board and disembark from aircraft. Within the terminal, passengers purchase tickets, transfer their luggage and go through security.
