Navigation Strategies Accuracy - wichtig
Level of accordance of actual from intended aircraft position, usually expressed statistically with a confidence interval of 95%
Navigation Strategies Integrity - wichtig
das luftfahrzeug ist in der lage festzustellen, ob grenzen überschritten werden und davor warnt
Navigation Strategies Continuity - wichtig
Ability of navigation system during operation to remain in service without unpredicted malfunctions (minor failure condition)
Navigation Strategies Availability - wichtig
Ability of navigation system to provide all necessary information at the beginning of a selected operation
Navigational Accuracy -lateral + total error - wichtig
Navigational Accuracy -lateral
Navigational Accuracy -longitudinal
RNAV
Random Navigation resp. Area Navigation (RNAV) is a navigation process where an aircraft operates on any intended flight track within the range of ground navigation facilities or with autonomous on board navigation systems or with the help of satellite navigation
−continuous position determination with usage of one or more sensors for determination and to ensure compliance to intended flight track
RNAV vorteile
→improvement of safety and capacity of airspace
→improvement of efficiency by reducing the distances flown and improved prediction for flight information and gate management (airline)
→reduction of fuel consumption and emissions
→reduction of operating costs for ground navigation equipment
PBN
basically
RNAV + on board self contained performance monitoring and alerting
also flugzeug schätzt selbst ein ob es in der genauigkeit liegt -> prüft navigations genauiogkeit

3 Grundfragen der Navigation
Unterschied Ortung und Navigation
Location:
position
state of motion
properties of the measured or perceived information (z.B. qualität der information)
Navigation:
driving a vehicle from a point of departure A to a destination Z
Air navigation categories
Was ist cooperative navigation + examples
radio navigation systems are based on the interaction of the radio equipment on the aircraft and that in ground stations or satellites
VHF omnidirectional radio range (VOR)
Non-directional beacons (NDB)
Distance Measuring System (DME)
Global Navigation Satellite Systems GNSS (GPS, GLONASS, GALILEO)
Autonomous navigation systems + examples
Autonomousnavigation systems are characterized by the fact that the location or position is determined only by on board or ground based devices, independent of a remote station.
primary radar (dopplerradar)
direction finder systems
radio altimeter
Inertial navigation systems (INS/IRS)
was ist ein kurs
is an angle measured in the horizontal plane.
counting clockwise from a reference direction to be specified from 000°to 360°.
was ist der True North (TN) / rechtweisend Nord (rwN) - wichtig
Guidance to the geographic north pole
was ist der MagneticNorth (MN) / missweisendNord (mwN) - wichtig
Guidance to the magnetic north pole delta between TN –MN: magnetic declination or magnetic variation (VAR)
reasons for the variation: secular variation of the magnetic north pole
disturbance of the magnetic lines of forces caused by local magnetic field anomalies
was ist der Compass North (CN) / (Magnet) KompassNord (KN) - wichtig
guidance to themagnetic north pole, whose position is offset by external influences
delta between MN -CN: deviation (DEV)
reasons for the deviation: interference by on-board electric/magnetic fields
schematische darstellung der "north directions" -wichtig
was ist hiermit gemeint
what are MC and CC
Course vs Heading vs Track
was ist der drift angle bzgw Abdriftwinkel
