Navigation Flashcards
For operations off established airways at 17,000 feet MSL in the contiguous U.S., (H) Class VORTAC facilities used to define a direct route of flight should be no farther apart than
200 NM
You are planning an IFR flight off established airways below 18,000 feet MSL. IF you use VOR navigation to define the route, the maximum distance between NAVAIDs should be
80 NM
Which distance is displayed by the DME indicator?
Slant range distance in NM
where does the DME indicator have the greatest error between ground distance to the VORTAC and displayed distance?
High altitudes close to the VORTAC.
(Refer to Figure 240.) how should a pilot determine when the DME at price/carbon county airport is Inoperative?
the airborne DME may appear normal, but there will be no code tone.
(Refer to figure 240.) How should a pilot determine when the DME at PUC airport is inoperative?
The airborne DME may appear normal, but there will be no code tone.
which DME indication should you recive when you are directly over a vortac site at approximately 6,000 feet AGL?
1
As a rule of thumb, to minimize DME slant range error, how far from the facility should you be to consider the reading is accurate?
One or more miles for each 1,000 feet of altitude above the facility.
When a VOR/DME is collocated under frequency pairings and the VOR portion is inoperative, the DME identifier will repeat at an interval of
30 Second intervals at 1350 Hz
What is the meaning of a single coded identification received only once approximately every 30 Seconds from a vortac?
The DME component is operative and the VOR component is inoperative.
(Refer to figure 192.) as a guide in making range corrections, how many degrees of relative bearing change should be used for each one-half mile deviation from the desired arc?
10° to 20°
How does a pilot determine if DME is available on an ILS/LOC?
IAP indicate DME/TACAN channel in LOC frequency box.
