a) a precision approach

b) a non-precisionn approach

a = 90 degrees

b = 120 degrees

12

What is a procedure turn?

What are the two types?

a manoeuvre in which a turn is made away from a designated track followed by a turn in the opposite direction to permit the aircraft to intercept and proceed along the reciprocal of the designated track

Two types are the 45/180 and 80/260 procedure turns

13

What is a base turn?

consists of a specified outbound track and timing or DME distance from the facility, followed by a turn to intercept the inbound track where the tracks are not reciprocal
