Questions for R* B*LI RADAR

Answer the following questions

2. A VOR/DME share the same first two letters of their respective identifiers; the last identifying letter of the DME is a Z. This means that
3. DME and VOR are frequency paired because
4. The aircraft DME receiver cannot lock on to interrogation signals reflected from the ground because
5. Distance Measuring Equipment (DME) operates in the
6. Airborne DME equipment is able to discriminate between pulses intended for it self and pulses intended for other aircraft because
7. A DME in tracking mode subsequently experiences a reduction in signal strength will switch the equipment in the first instance to
8. In which situation will speed indications on a airborne Distance Measuring Equipment (DME) most closely represent the groundspeed of an aircraft flying at FL 400?

11. If a VOR station and a DME station, having different locations, are selected to provide a fix
12. If an ident signal is received once in 30 seconds on a frequency paired VOR/DME, then:
13. When a DME is used insted of marker beacons to provide range to the threshold on an ILS approach and where the DME frequency is paired with the ILS, the DME indications should not be used at altitudes greater than
14. During a flight at FL210, a pilot does not receive any DME distance indication from a DME station located approximately 220NM away. The reason for this that the
