Q

What are these brown airways?

A

MTR: Military Training Routes

VR = Visual Route ; conducted in accordance with VFR except flight visibility must be 5 miles or more; and flights must not be conducted below a ceiling of less than 3,000 feet agl

IR = Instrument Route ; conducted in accordance with IFR regardless of weather conditions.

A three-digit route number means at least one route segment has one or more segments above 1,500 feet agl. A four-digit MTR has no segments above 1,500 feet agl—including instrument routes.

Q

What is this?

A

Fly by waypoint, you can lead the turn.

17
Q

What is this?

A

Fly Over waypoint, you need to fly over it.

18
Q

IFR Low enroute Airport identifications

Blue

Green

Brown

A

Blue - has an approved IAP

Green - has an approved IAP

Brown - NO IAP

19
Q

What is this?

A

Prescott FSS (flight service station), RCO (remote communications outlet) or AWOS not associated with a NAVAID or an airport.

20
Q

What are the things circled?

A

Top: FSS (Flight Service Station) frequency

Middle: TUS Vortac frequency 116.0. Underlined means no voice transmitted on frequency

Bottom: name of FSS (PRESCOTT)

21
Q

What airspace is Pheonix Sky harbor and how could you tell?

A

Class Bravo; Solid blue line

22
Q
A

Distances between fixes on a victor airway

23
Q
A

Brown = no approach altitudes

Tick marks on low enroute = civilian airport

24
Q
A

distance from casa grande muni to that fix (14nm)

25
Q

what airspace does this designate?

A

Bravo airspace = solid blue line with shading

26
Q

What do the two closed dashed line mean?

A

Higher MEA ahead, change in altitude.

At the line, expect ATC to clear you to the new MEA, from your original MEA.

27
Q

What are these (T) symbology?

A

type of vor:

(T) = terminal

(L) = low

(H) = high

(Y) = tacan

28
Q

Shaded vortac vs non-shaded vortac?

A

Shade = compulsory reporting points (non-radar contact)

Non-shaded = non-compulsory reporting point

29
Q

Decode this description of MYF

A

San diego = city

Montgomery-Gibbs Exec = name of airport

(MYF) = ICAO identifier

squared D = class D airspace

star = part time tower

427 = airport elevation

L = lighting available ; circle L = pilot controlled lighting

ASOS = Automated Surface Observation System

126.9 = tower freq

(A) = ATIS ; star = part time ; ATIS freq. = 126.9

30
Q

What is the shaded green area?

A

body of water

31
Q

What is this shaded area?

A

Golf airspace from SFC to 14,500 MSL

32
Q

What is the dashed brown lines?

A

MOA = Military Operating Area

Instrument Oral (7 decks)
