24
Q

Why is there a different distance displayed on an A/C based on their actual position? (1)

A

Slant range

25
Q

Are pilots required to adjust headings and timings to allow the affect of wind? Yes or no

A

Yes

(Must inform ATC if they cannnot comply)

26
Q

When will an aircraft be told of an Expected Approach Time (EAT)? (1)

A

A time at which to expect to leave the hold to commence an instrument approach - 10 minutes or more

27
Q

What is an Expected onward Clearance time? (1)

A

Time to leave the hold to continue enroute

28
Q

What will a pilot do when told a specified time to leave the hold? (1)

A

Pilot will adjust timing within the pattern to leave at a specified time

29
Q

What is the normal separation from a holding pattern? (1)

A

1. 5 minutes
2. From the flight path of the holding aircraft

30
Q

What should a Holding area provide? (1)

A

Separation from aircraft in the hold from aircraft outside of the holding area

31
Q

Protected area of a holding pattern diagram

A
32
Q

What will ATC need to know with a holding pettern? (1)

A

Be aware of the dimensions of the holding area in order to calculate this

33
Q

What will the Authority calculate & determine with a holding pettern? (1)

A

Which of adjacent holding patterns can be “deemed” as separated

34
Q

Where may VFR aircraft commence VFR holding? (1)

A

VRP’s
Visual Reference Points

35
Q

What do VRP’s do? (1)

A

Assist ATC routing VFR traffic and integrate it with IFR flights

36
Q

What must ATCO’s do with VRP’s outside controlled airspace? (1)

A

ATCOs should not instruct an A/C to hold / route OVER such VRPs

37
Q

What may A/C be told after they are allowed to commence an approach? (1)

A

May be told to orbit until sufficient spacing has been achieved or the pilot reports visual with the aircraft he is following
