Part 121

Question 1

What does this part prescribe?

Answer 1

PAX seating of greater than 30 seats or a payload capacity greater than 3410kg

Question 2

What category of airworthiness is required?

Answer 2

A current standard CoA.

Question 3

What are the minimum heights for VFR?

Answer 3

Pt91… not below 1000ft above congested town/area or assembly of people at radius of 600m. Not below 500ft at radius of 150m of highest obstacle.
However rule 91.311c does not apply, which allows descent below 500ft in bona fide cases.

Question 4

Are VFR night operations allowed?

Answer 4

No PAX operations at night VFR.

Question 5

What are the common language requirements?

Answer 5

All crew members must be able to communicate in a common language and all ops personnel must be able to read the CH exposition. And the flight crew members must be able to communicate in English.

Question 6

What are the VFR met conditions required?

Can you fly over water?

Answer 6

Must not perform extended over water ops VFR (more 50Nm).

As per 125

Question 7

What are the IFR met conditions required?

Answer 7

PIC must not commence IFR, unless if combination of current met forecasts/reports or reports indicate:
-at ETA wx will be above the minima published in the AIP for the IA a likely to be used.
And at the estimated time of use:
-1 ALT AD meeting ceiling/vis req (+/- 1hr)… if this can’t be met
-2 ALT AD meeting ceiling/vis req (ALT AD)

Question 8

Do P121 ops always require an alternate?

Answer 8

Must not commence IFR unless there is at least 1 alternate that meets ALT AD minima if…

• the dept/arr AD is outside of NZ
• the destination has less than 2 useable RWY for the a/c

Question 9

What considerations are there for calculating T/O distance?

Answer 9

TOW does not exceed MCTOW.
When calculating MCTOW, assuming critical engine fails at Vef using a single V1, ensuring:
-ASDR does not exceed ASDA & TORR does not exceed TORA.
-Any clearway forming apart of TODA shall not exceed 1/2 TORA.
-TODR is calculated to point where a/c is 15ft above SFC using reduced V1 for wet/contaminated RWY
-On wet/contaminated RWY, TOW does not exceed what is permitted on a dry RWY under the same conditions
-Usual ele, PA, *c, sfc conditions/type, slope, wind

Question 10

What are the performance requirements for landing distance?

Answer 10

Estimated LDW not exceed MLW.
LDR is 50ft above threshold to full stop for dry RWY.
TF/TJ must full stop in 60% LDA, 70% for props.
And the usual performance factors (wind, elevation etc)

Question 11

What are the weights to be used to calculated the weight of the a/c?

Answer 11

Can be actual weight of baggage and PAX.
Can be a standard weight:
-Under 2=15kg
-2 through 13= 46kg
-13+ = 86kg
-Crew+bag= 86kg

Question 12

What are the requirements for flight over water?

Answer 12

Extended over water operations must be equipped with sufficient life rafts with buoyancy and overload capacity to accomodate every occupant if life raft of largest size is lost.

Question 13

What is the required emergency equipment?

Answer 13

Same as 125…
But also flights more than 120m should be equipped with emergency medical kits suitable for use by medical professionals containing items for treating injuries and medical emergencies.

Question 14

What are the GPWS/TAWS requirements?

Answer 14

G: Each turbine powered a/c requires GPWS unless TAWS class A equipped.

T: Each turbine powered a/c shall have TAWS class A equipped.
    Each piston powered a/c shall have TAWS class B equipped.

Question 15

Who must the maintenance review be carried out by?

Answer 15

Every 12m by a P145 engineer.

Question 16

What number of flight attendants are required?

Answer 16

Either:

• recommenced by manufacturer for evacuation procedure for the configuration used
• as specified in the certified design criteria for the a/c
• Seat capacity:

15-50:1
51-100:2
101-150:3
151-200:4
201-250:6
251-300:7
301-350:9
351-400:10
401-450:11
450-500:12
500+: 12 + 1 for every 50 PAX or part of
Must be at least 1 FA per occupied PAX compartment

Question 17

What additional rules are there for FA?

Answer 17

AO requiring 2 or more FA requires a senior FA responsible to the PIC for operational and safety functions of each FA.
AO requiring 6 or more FA requires a deputy senior FA.
May operate with one less FA from the table, due to illness or injury as long as the other requirements can be met and the FA are trained and competent to operate safely with one less FA.
