Question 11

what is the evaluated area of a DME arc?

Answer 11

an area between which the arc has been assessed for terrain clearance

Question 12

to what distance either side of an arc is terrain evaluated and what is the flight tolerance?

Answer 12

evaluated 2.5nm either side with a 1nm flight tolerance

Question 13

what do lead radials on an arc provide?

Answer 13

a 2nm lead on the inbound turn

Question 14

when may an aircraft join an arc from the inside?

Answer 14

• training in controlled airspace

Question 15

how do we correcting an arc if we are inside the arc?

Answer 15

• position the bearing pointer below the datum
• continue making turns to keep the bearing pointer below the datum
• once at the correct distance turn to position 5 degrees above the datum
