Routes, Airways, Charts Flashcards
Airways
paths of the sky in controlled airspace
Air routes
paths in the sky in uncontrolled airspace
Low-level airway
Route within low-level airspace
From 2200ft AGL up to, but not including 18000ft ASL
VHF/ UHF airways
Airways from 1 VOR/ VORTAC to another
Indicate by letter V, known as Victor airways
VOR
VHF omnidirectional range station
VORTAC
VOR that also has a tactical air navigation beacon (TACAN)
VHF/ UHF airway dimensions
4NM on either side of the airway centreline to a distance of 51NM from VOR
then within lines that diverge at 4.5 degrees until they meet similar lines form adjacent NAVAID
LF/ MF airways
Airways extend from 1 non-directional beacon (NDB) to another
LF/ MF airway dimensions
4.34 NM on either side of the airway centreline to a distance of 50NM from NDB
within lines that diverge at 5 degrees from NDB until they meet similar lines form adjacent NAVAID
Combination VHF/ UHF and LF/ MF airways
Extend between VOR/ VORTAC and an NDB
Dimensions of combination VHF/ UHF and LF/ MF aiways
4.34NM on either side of the airway centreline to a distance of 50NM from NDB
within lines that diverge at 5 degrees from NDB until they meet similar lines from adjacent NAVAID
(same as LF/MF airways)
Dimensions of combination VHF/ UHF and LF/ MF aiways
4.34NM on either side of the airway centreline to a distance of 50NM from NDB
within lines that diverge at 5 degrees from NDB until they meet similar lines from adjacent NAVAID
(same as LF/MF airways)
T-route
Fixed low-level controlled RNAV route
Requires GNSS and RNAV systems for use
Dimensions of T-route
10NM on either side of the centreline
Does not splay
Low-level air route
Route within low-level uncontrolled airspace
ATC service is not provided
L-Routes
Fixed RNAV routes that requires RNAV and GNSS systems for use
(in low-level uncontrolled airspace)
