A

a. a preceding departing aircraft using the same runway is

airborne and:

(1) has commenced a turn; or

(2) is beyond the point on the runway at which the landing aircraft could be expected to complete its landing roll and there is sufficient distance to manoeuvre safely in the event of a missed approach;

100
Q

Taxiing After Landing?

A

10.1.1 After landing, the runway strip should be vacated as soon as practicable. Aircraft should not stop until clear of the runway strip.

101
Q

For determining requirements, the cumulative cloud amount is interpreted as follows?

FEW plus FEW is equivalent to SCT,

FEW plus SCT is equivalent to BKN,

SCT plus SCT is equivalent to BKN or OVC

102
Q

When weather conditions at the destination are forecast to be as specified at para 10.7.2.1, but are expected to improve at a specific time, provision for an alternate aerodrome need not be made if sufficient fuel is carried to allow the aircraft to hold until that specified time plus ?

A

30 minutes

103
Q

You need to carry an alternate if your visibility is greater than the alternate minimum, but the forecast is endorsed with at least a ?

A

a 30% percentage probability of fog, mist, dust or any other phenomenon restricting visibility below the alternate minimum; or

d. a thunderstorm or associated severe turbulence, or a forecast of at least a 30% probability of such an event

104
Q

You need to carry an alternate if your visibility is greater than the alternate minimum, but the forecast is endorsed with at least a ?

A

a 30% percentage probability of fog, mist, dust or any other phenomenon restricting visibility below the alternate minimum; or

d. a thunderstorm or associated severe turbulence, or a forecast of at least a 30% probability of such an event

105
Q

a. When the weather following the FM or BECMG is forecast to create an operational requirement, that operational requirement will become effective ?

A

30 minutes before the start

of the FM time, or 30 minutes before the start of the BECMG

period.

106
Q

b. When the weather following the FM or BECMG is forecast to remove an operational requirement, that operational requirement will remain effective until ?

A

30 minutes after the FM time or 30 minutes after the end of the BECMG period

107
Q

At aerodromes receiving a TAF3 service, and only during the first 3 hours of the TAF3 validity, not beyond the end time for the TAF3 service if such a time is specified, the following do not apply?

A

a. 30 minute buffers required by paras 10.7.2.7 and 10.7.2.8,

b. the alternate or holding fuel required by:

(i) para 10.7.2.1 (c) for reduction in visibility, or

(ii) para 10.7.2.5 for any PROB30 or PROB40 for TS or associated severe turbulence

108
Q

MINUMUM FUEL
1 The pilot in command shall advise ATC of a minimum fuel state by declaring?

A

MINIMUM FUEL when, having committed to land at a specific aerodrome, the pilot in command calculates that any change to the existing clearance to that aerodrome may result in landing with less than final reserve fuel.

109
Q

Emergency Fuel

10.9.3.1 The pilot in command must declare a situation of emergency fuel by broadcasting ?

A

MAYDAY MAYDAY MAYDAY FUEL, when the calculated usable fuel predicted to be available upon landing at the nearest aerodrome where a safe landing can be made is less than the final reserve fuel

110
Q

Note 1: MAYDAY FUEL declaration is a distress message.

Note 2: In circumstances where a normal approach and landing is expected and the pilot assesses there is no requirement for emergency services, ATS should be so advised as early as possible e.g ?

A

“EXPECTING NORMAL APPROACH AND LANDING, EMERGENCY SERVICES NOT REQUIRED

111
Q

Where do we find information on TIBA ?

A

AIP ENR1.1-91

112
Q

For GPS (GNSS) approaches, RAIM must be available at the Final Approach Fix (FAF),
as indicated by the ?

A

GPS INTEG annunciator extinguished

113
Q

Default RNP values FMS ?

A
  1. Enroute: 2.00
  2. Terminal: 1.00
  3. Approach: 0.30
114
Q

Default RNP values FMS ?

A
  1. Enroute: 2.00
  2. Terminal: 1.00
  3. Approach: 0.30
115
Q

What must you do in controlled airspace if you get POSITION UNCERTAIN ?

A

The FMS position is unreasonable (not verified). ANP values
have reached or exceeded the RNP.
Note: If in controlled airspace, ATC must be advised
immediately: “UNABLE RNP (OR RNAV) DUE TO POSITION
UNCERTAIN

116
Q

What must you do in controlled airspace if you get NO SATELLITE INTEG” (Loss of RAIM) ?

A

If in controlled airspace, ATC must be advised if RAIM has
been unavailable for more than 5 minutes: “UNABLE RNP (OR
RNAV) DUE TO LOSS OF RAIM

117
Q

What must you do in controlled airspace if you get SATELLITE POS ALARM” (RAIM ALERT) ?

A

GNSS position error outside Integrity Alarm Limit (IAL). Level
of integrity known to be unacceptable.
Note: If in controlled airspace, ATC must be advised if a RAIM
Alert has exceeded 1 minute: “UNABLE RNP (OR RNAV) DUE
TO RAIM ALERT

118
Q

What must you do in controlled airspace if you get DEAD RECKONING MODE ?

A

True airspeed and heading are the only sensors being used
for navigation.
Note: If in controlled airspace, ATC must be advised if the GNSS
receiver is in dead-reckoning mode for more than 1 minute:
“UNABLE RNP (OR RNAV)
