What must a pilot verify before using a VOR station?
Correct and usable VOR station with morse ID.
What does the VOR MON program ensure?
A MON airport is available within 100 NM regardless of aircraft position in the CONUS.
How often must VOR receiver checks be performed according to §91.171?
Every 30 calendar days.
What is the permissible error for a VOT check in a VOR receiver check?
±4º.
What is the permissible error for a repair station check in a VOR receiver check?
±4º.

±6º.
What is the permissible error for a dual VOR cross-check?
±4º.
What is the permissible error when checking VOR above a prominent ground landmark on a selected radial at least 20 NM from a VOR?
±6º.
What information must be included in a VOR check sign-off according to §91.171?
D.E.P.S - Date, Error (bearing error), Place, Signature.
Name a limitation of VOR related to signal distortion.
Cone of confusion.
What is a limitation of VOR if used incorrectly?
Reverse sensing.
What is a basic requirement for VOR functionality between aircraft and station?
Requires line-of-sight.
What is the standard service volume range for a Terminal VOR under MON?
25 NM.
What is the altitude range for a Terminal VOR under MON?
Up to 12,000 ft.
What is the new service volume range for a Low (VL) VOR under MON?
70 NM.
What is the new altitude range for a Low (VL) VOR under MON?
Up to 18,000 ft.
What is the new service volume range for a High (VH) VOR under MON up to 14,500 ft?
100 NM.
What is the new service volume range for a High (VH) VOR from 14,500 ft to 18,000 ft?
100 NM.
What is the service volume range for a High (VH) VOR from 18,000 ft to 45,000 ft?
130 NM.
What is the service volume range for a High (VH) VOR from 45,000 ft to 60,000 ft?
100 NM.
What is the frequency range for Distance Measuring Equipment (DME)?
962-1213 MHz (UHF).
How is DME normally tuned?
Automatically with a paired VHF station (VOR/LOC).
What signal does the airborne DME unit transmit?
An interrogation signal.
How does the ground DME facility respond to the airborne DME unit?
It receives and replies to the interrogation signal.
How does the airborne DME unit calculate the distance to the station?
By calculating the slant range distance based on the reply time.
What does DME indicate when flying overhead the station due to slant range error?
Greater than zero.
When is slant range error negligible for a DME station?
At 1 NM DME station per every 1000 ft height.
Give an example of negligible slant range error for DME.
At 5000 ft, slant range error is negligible when further than 5 NM from the station.
What is the DME low (DL) service volume range?
130 NM.
What is the DME high (DH) service volume range?
130 NM.
What is the frequency range for a Non-Directional Beacon (NDB)?
190-535 kHz.
What does the ADF (Automatic Direction Finder) in an aircraft point towards?
The NDB.
How do you calculate Magnetic Bearing using an NDB?
Magnetic Bearing = Magnetic Heading + Relative Bearing.
What is a compass locator in the context of NDB?
A low-powered NDB installed at the Outer Marker (OM) or the Middle Marker (MM) on some ILS approaches.
What is the service volume range of a compass locator?
15 NM.
What is the service volume range of a Medium High (MH) NDB?
25 NM.
What is the service volume range of a High (H) NDB?
50 NM or less, see NOTAM or Chart Supplement.
What is the service volume range of a High High (HH) NDB?
75 NM.
