Block 3 Flashcards
What are the dimensions of a Victor Airway?
- 8nm wide
- If farther than 51nm form any station the width expands to include airspace within a 4.5 DEGREE ANGLE from the navaid
IFR Low Charts show airways Victor Airways below _____ MSL
18,000’ MSL
What routes do IFR High Charts show?
18,000’ MSL and above
Jet Routes
Pointer on the compass rose indicates ___ North
Magnetic North
What color are RNAV Routes?
Blue!! They are based off GPS.
What are the different designations for GPS routes below 18,000’ and at or above 18,000’?
T-Routes (below 18)
Q-Routes (18+)
What ON-route altitude gives you obstacle clearance for the whole route, and reliable navigation signal within 22nm of the facility?
*MOCA
True or False: You must always report to ATC when crossing compulsory reporting points.
False
- You must only report when NOT IN RADAR CONTACT
What altitude do you use when planning OFF-route in IFR? What does it guarantee you?
OROCA
- Off Route Obstacle Clearance Altitude
- Obstacle clearance guarantees only…this is where VOR SSVs come into play
What is the lowest altitude between radio fixes that guarantees navigation reception and obstruction clearance?
MEA
On GPS routes its given with a G at the end ####G
MAA guarantees you will receive:
Only one VOR
- Prevents NAVAID interference
What is the purpose of MRA flags on airways?
Tells us the lowest altitude that ensures adequate reception from an OFF-ROUTE NAVAID used to identify a fix (aka using a different NAVAID to help identify a fix along your route)
What does an MCA signify?
That is the altitude we must BE AT before crossing the fix (usually present when MEA is increasing along a route)
How many instrument approaches does an airfield depicted in BROWN have?

How many instrument approaches does an airfield depicted in GREEN have?
At least one (1) FAA IAP
How many instrument approaches does an airfield depicted in BLUE have?
At least one (1) Dept of Defense IAP
