Part 125

Question 1

What operations does part 125 cover?

Answer 1

A/c with:

• PAX seating of 10-30 seats
• MCTOW greater than 5700kg or max payload 3410kg or less
• SEIFR PAX operations

Question 2

What are the a/c airworthiness requirements under P125?

Answer 2

A current standard category certificate of airworthiness.
For SEIFR ops:
-turbine powered and IFR capable
-comply with airworthiness standard equivalent to min FAR23 AMD08
-Prop and engine models min 100,000hr time in service in same type of a/c and demonstrated mechanical IFSD rate of not more than 1/100000hr

Question 3

When must a flight plan be filed? By whom? Must there always be an ATS flight plan?
Can SARTIME be amended?

Answer 3

A VFR/IFR flight plan must be filed/submitted by the PIC or operation personnel. If not made by PIC, they must be informed of the contents.
VFR flight plan may incorporate multiple route segments provided the SARTIME is appropriately amended. However VFR flight plan is not required if non stop flight dept/arr at the same AD and remains within 25Nm of depth AD, but must at least have a flight following service if not followed by ATS.

Question 4

Just know this…

Answer 4

Appropriate info must be available to PIC to complete intended flight.

Question 5

What responsibilities are there on each person performing an air operation in terms of PAX safety?

Answer 5

• PAX are to be seated as so they do not hinder evacuation in case of emergency.
• PAX under the influence or exhibits characteristics of drugs/alcohol may be refused boarding/removed from flight.
• Disabled PAX must be appropriately seated and taken care of, and assisted in case of emergency. PIC must be notified they are on board.
• Children under 15yr or adults with infants must not be seated in any seat row next to emergency exit.

Question 6

Who can manipulate the controls?

Answer 6

Reasonable precautions to be taken to ensure no person manipulates the flight controls on AO unless:

• they are a flight crew member
• they are authorised rep of the director who has permission of CH & PIC and performs a required duty

Question 7

What conditions surround refuelling/refuelling with PAX?

Answer 7

• May re/defuel the aeroplane with class 3.1C/D flammable liquids when people are embarking/disembarking/on board providing the person operating the a/c ensures safety and evacuation procedures are taken IAW CH exposition.
• May re/defuel the aeroplane with class 3.1C/D flammable liquids with one or more propulsion engines running provided the PIC is responsible for every aspect of the fuelling operation and every PAX is disembarked under the supervision of a crew member and is clear of the immediate are before re/defuelling begins.

Ie) so an ATR can’t refuel with PAX if APU runs as APU is a propulsion engine

Question 8

What information is required to be documented for SEIFR flights? How often?

Answer 8

In house program established to ensure early identification & prevention of SEIFR issues that include:

• recording of any event that compromises SEIFR safety due to potential risk
• report when SEIFR flight was not dispatched due to WX below available alt AD planning
• for each a/c a maintenance database designed to access reliability of a/c & systems including: number SEIFR flights per month, details of any diversion from SEIFR op, number times a/c was not dispatched on SEIFR op due US
• compliance with engine manufacturers extended maintenance program

Information above is reviewed at the end of each calendar month and any corrective/preventative actions recorded, except after 6m, if approved by the director, may be extended to the end of 3 calendar months.

Question 9

What additional training must SEIFR pilots undergo?

Answer 9

• integrate any MEIFR/SEVFR flight experience into SEIFR PAX
• conduct/avoid SEIFR PAX op into icing
• conduct SEIFR PAX op at night
• enable flight crew to take appropriate action in the event of any non normal warning/indication

Question 10

This is cause you are NOT allowed too SEIFR PAX op as a CTO

Question 12

What VFR Met minima applies to 125 ops?

Answer 12

P91 minima applies.
Not fly in conditions of ceiling less than 1000ft AGL/less 5km vis, and fly beneath a ceiling of cloud and in continuous sight of ground or water and not fly above more than scattered cloud.

Question 13

When can (under p125) you fly in an air operation above more than scattered cloud?

Answer 13

When the a/c:

• equipped with operative instruments/equipment that are required for IFR flight, including radio nav equipment.
• capable with 1 engine inoperative to maintain a +ve slope net flight path 1000ft above the cloud

• carries sufficient fuel/reserves to proceed IFR to AD where IAP may be carried out

Question 14

What meteorological conditions are required for IFR flight?

Answer 14

PIC of a/c in AO must not commence IFR unless combination of current forecasts/reports OR current forecasts indicate that:

• met conditions at destination AD at ETA will be at/above the minima published in the AIP for the likely IAP… OR
• met conditions (ceiling/vis) will be met at the alt AD

Question 15

What is the IFR AD minima?

Answer 15

POC must not continue on an IA past the FAF (or if no FAF commence final approach segment), if before these points the current met info indicates the vis at the AD is less than the published min vis for the IAP in the AIP.

Question 16

What IFR departure limitations are there?

Answer 16

Each person performing an IFR ATO shall ensure flight is not commenced when WX conditions are at or above TO minima but below the landing minima, unless the aeroplane is ME and there is an appropriate AD:

• For 2 engine a/c, within 1hr max flying time in still air at 1 engine inoperative cruising speed of dept AD
• For 3+ engine a/c, within 2hr max flying time in still air at 1 engine inoperative cruising speed of dept AD

Question 17

What is the reduced TO minima conditions for 125?

Answer 17

Operator may operate a ME a/c at a lower T/O minima if the operation is conducted IAW the reduced T/O minima procedure in the CH exposition which must include:

• every flight crew is qualified for the RMTO
• RWY has centreline marking lighting
• RWY has reduced T/O minima published in AIP
• if twin (prop) has auto coarse/feather
• if RWY vis is established using RVR then a method of confirming/observing vis that is acceptable to the director

Question 18

What 3 conditions surround T/O performance?

Answer 18

TOW does not exceed MCTOW
TODR does not exceed 85% TORA
Max 50% HWC, min 150% TWC

What conditions surround the net T/O flight path performance?

Answer 19

A/c with 2 or more engines operating IFR if the critical engine is inoperative, all obstacles within the net T/O flight path are cleared by at least 50ft vertically.
When calculating the net T/O flight path the following must be considered:
-TOW at commencement of T/O run

• If a/c above 5700kg, full stop 70% LDA
• 50% HWC, 150 TWC

Question 22

What are the landing distance requirements for wet/contaminated RWY?
