Q

For private and aerial work flights, when does an alternate have to be provided

A

when there is less than 1 instrument approach procedure other than a GPS dependent approach.

Q

For charter and RPT operations, the pilot must be able to suffer the failure of an airborne aid and still conduct an approach. This means that these flights require

A

2 ADFs or 2 VORs or if the aerodrome has 1 NDB and 1 VOR, then one of each is required.

Q

When may pilots refer to the special alternate minima printed in the notes on the right side of the daps chart

A

When the aircraft is fitted with 2 independent ILS receivers. Obviously this only occurs for aerodromes with ILS available.

Q

We don’t need an alternate for aerodrome with PAL lighting if…

A

STBY power or portable lights available
or
Someone is there 30min before ETA to lay the portable path and remains until taxi is completed.

Q

How do we accomodate for PAL lighting alternate requirements

A

We need an alternate unless a responsible person is in attendance to manually switch on the runway lights within 30min of ETA and remain after taxi.

Q

What is the special deal for lighting alternates

A

Your alternate can be a PAPI aerodrome and not have someone in attendance, so long as your flight is not passenger carrying or PRT/charter >3500kg, and the aircraft has dual VHF or one VHF and one HF.

Q

What buffer applies for INTERS and TEMPO

A

30 min before and after. therefore if your arrival falls within 30 min of an INTER or TEMPO, you need holding fuel sufficient for the INTER or TEMPO (30 min or 60 min)

Q

If we have a TAF and a TTF, which do we go by?

A

tthe TTF supersedes the TAF, therefore we go by what the TTF says.

Q

What is the max distance you can fly between position fixes.

When planning IFR flights, what guidelines should you follow

A

those set out in ERSA GEN FPR

25
Q

If an object is below 360 ft, how much height do we have to add to give LSALT?

A

1360ft

26
Q

If a an object is bigger than 360 ft, how much height do we need to add to the LSALT?

A

1000ft

27

28
Q

What does the term squawk charlie mean?

A

select the pressure altitude function on the XPDR

29
Q

When are we NOT able to manoeuvre on an approach

A

You can’t manoeuvre in a sector once you have passed the final approach fix

30
Q

How do you calculate ROD if the glide slop is 3 degreer

A

apparently 3 degrees = 5%, so multiply ground speed by 5

31
Q

How much do you have to add to the ILS minima if you don’t have PEC

A

50ft

32
Q

If HIAL isn’t available due u/s for ILS, how much is our vis

A

1.5

33
Q

if HIAL isn’t available due u/s for LOC, how much is our vist

A

900m added to the current minima

34
Q

If you are intending to TO into CTA, what should your XPDR be set to?

A

ALT

35
Q

If a controller tells you to “stop squawk”, what does this mean?

A

turn off your fucking transponder

36
Q

What is the order of navigation aid selection preference

A

GNSS, VOR, then NDB

37
Q

What is the bearing refraction when they cross the coast at 90 degrees.

A

There is no refraction when the bearings cross the coast at 90 degrees

38
Q

What is ephemeris data

A

the calculated orbital position of the satellite

39
Q

If you are taking off from an aerodrome without an instrument approach, you can’t take off unless…..

A

the visual approach will be possible from LSALT

40
Q

to be considered “established on final approach”, what are the tolerances for ILS, VOR or GNSS, and NDB and DME

A

+/- 5nm for ILS VOR or GNSS

+/- 2nm for NDB and DME

41
Q

When should you start squawking an assigned code

A

just prior to entering CTA

42
Q

Should you pass upwind or downwind of bad weather

A

upwind

43
Q

What is the minimum TO minima for OZY

A

300ft cloud and 2km vis

44
Q

If you don’t have a DME or GPS, when can you descend below the LSALT

A

when over the IAF

45
Q

At night, when can we descend below the MSA?

A

When we are within the circling area

46
Q

when do you need to broadcast your approach position on ctaf

A

final inbound track

47
Q

Do 30 min buffers apply to TTF?

A

no, they are accurate enough to not need this

48
Q

When does the special alternate minima apply to aircraft?

A

When they have 2 independent ILS receivers.
