Q

Using the same beacon and intercepting a new radial at different distance

A

Visualise the aircraft on the compass rose and use the outer circles as distances. Transfer these on the centre of the compass rose and you can figure out the distance and radial

Q

Reversal procedure

A

Reversal is required if the hold is in the same plane as the outbound track. Therefore as you fly over the beacon you make a tear drop to turn onto ourbound.

If arriving within 30 deg of outbound you can join straight on

If 30 of reversal heading could joking straight into tear drop

Q

Race track procedure

A

Pretty much flying the hold outbound using corrected drift (x3) then when abeam beacon flying outbound on single drift.

Q

Outbound timing corrections

A

One second per knot of head or tail wind per minute

Procedure 3min outbound
20kts tailwind
20x3 = 60

Outbound is 2 mins

Q

Sops for parellel join

A

Correct timing at 1.5 times the headwind

Limit relative bearing to 20-25 degrees

Roll out of outbound turn when needle passes through the nose

Intercept 20 relative bearing

When it hits 25 degrees turn towards 20degreews to restore

Keep repeating until with 10degree

Then turn onto inbound heading with drift applied

Q

Using NDB with parrell entry SOPs

A

NDB is prone to dip when aircraft is turning so roll out when needle is less so around 5-10 degrees through the nose

16
Q

Offset join angle

A

30degrees from outbound radial or QDR

Correct for drift

1 minute correct for wind

17
Q

L3 SOPs checks at gate

A

60 degrees to go 30 degrees to go

18
Q

NDB dip correction

A

10-15 degrees

Needle drops down towards the direction of the turn

19
Q

60 degrees from inbound

Still air on track

A

VOR should be 10 degrees

ADF should be on

Right hand pattern!

20
Q

Overshooting under shooting turn inbound at 60 degrees

A

Overshooting
VOR less than 10
ADF less than inbound track

Under shooting (cutting inside)
VOR greater than 10
ADF more than inbound track

Right hand pattern!!!!

21
Q

Indications at 30 degrees

A

VOR + 3

ADF - 7

22
Q

Drift corrections

Wind from holding side

Bearing at 60 degrees

A

Blowing into the hold

X1 on inbound

x3 outbound if wind is surging 30degrees reduce to X2

Bigger than still at by about half the single drift value

23
Q

Drift

Wind from non holding side

A

Outbound X2 so to reduce risk of overshoot

24
Q

DME readings in hold

A

Because ILS coupled DME are of set to read zero at thresholds and may read zero in its protected bubble

25
Q

ILS cat and meaning?

A

Higher the Cat better the equipment

We operate cat 1 ILS

DH not less than 200ft
RVRgreater than 550m
Vis greater than 800m

26
Q

ILS identifiers

Rwys

A

26 IBH

08 IBMH

27
Q

Full scale deflection of VOR vs ILS

A

VOR 10 deg
ILS 2.5 deg

ILS is 4 x more sensitive

28
Q

What is a OM and LOM

MM

A

Outer marker 3.5-6nm out 1400ft

Co located NDB = locator outer marker

Middle marker - 0.5-0.8 , DH/ 200-250ft

29
Q

When should flap be lowered on instrument app?

A

Non Precison

  • ToD 0.3 nm
  • Asym Tod 0.1

ILS

  • 1/4 scale
  • when bottom of diamond touches centre
30
Q

DME arc protected area and flying tolerance?

Radius of turn?

A

+- 2.5nm

+-1nm

When joining a DME arc aim for 90 intercept and allow for 1% of ground speed for radius of turn. I.e
120kts allow 1.2nm before radius to turn

31
Q

Flying the DME arc?

A

Want to keep the needle pointed 90 degrees however this doesn’t work so

Fly to cut the circle 85 degrees allow to move through 90 to 95 then move back to 85 degrees

32
Q

Calculating distance along arc

A

60 divided by DME distance

Arc angle divided by answer

I.e

FAT is 158 deg
App trk is 204 degrees
DME radius = 12

60/12 = 5
46/5 -= 9
