15.5NCC.POL.120 Take-off mass limitations


The PIC is responsible for making sure that the aircraft never exceeds the mass limitations according AFM for T/O, reland after T/O and landing at destination. He also is responsible for making sure that he complies with the maximum weights for the OEI en-route requirements in regards to his route.

15.6NCC.POL.125 Take-off


When determining the maximum take-off mass, the pilot-in-command shall take the following into account:

  1. the pressure altitude at the aerodrome;

  2. the ambient temperature at the aerodrome;

  3. the runway surface condition and the type of runway surface;

  4. the runway slope in the direction of take-off;

  5. not more than 50 % of the reported head-wind component or not less than 150 % of the reported tailwind component; and

  6. the loss, if any, of runway length due to alignment of the airplane prior to take-off.

  7. the calculated take-off distance shall not exceed the take-off distance available with a clearway distance not exceeding half of the take-off run available;

  8. the calculated take-off run shall not exceed the take-off run available;

  9. a single value of V1 shall be used for the rejected and continued take-off, where a V1 is specified in the AFM; and

  10. on a wet or contaminated runway, the take-off mass shall not exceed that permitted for a take-off on a dry runway under the same conditions.

Wet and contaminated runway performance data, if made available by the manufacturer, should be taken into account. If such data is not made available, the operator should account for wet and contaminated runway conditions by using the factors:

Excluding airplane equipped with turboprop engines and a maximum take-off mass at or below 5 700 kg, in the event of an engine failure during take-off, the pilot-in-command shall ensure that the airplane is able:



  1. to discontinue the take-off and stop within the accelerate-stop distance available or the runway available; or

  2. to continue the take-off and clear all obstacles along the flight path by an adequate margin until the airplane is in a position to comply with NCC.POL.130.

The Obstacle clearance and a contingency procedure for departure requirements can be retrieved from commercial productions (APG), or produced by the Operator.

15.7NCC.POL.130 En-route — one engine inoperative


The pilot-in-command shall ensure that in the event of an engine becoming inoperative at any point along the route, a multi-engine airplane shall be able to continue the flight to an adequate aerodrome or operating site without flying below the minimum obstacle clearance altitude at any point.

This can be done by checking the lowest OEI cruising altitude if it is above the MSA, or by having drift down procedures applicable to the aircrafts performance and the planned route.

15.8NCC.POL.135 Landing


The pilot-in-command shall ensure that at any aerodrome, after clearing all obstacles in the approach path by a safe margin, the airplane shall be able to land and stop within the landing distance available. Allowance for expected variations in the approach and landing techniques, if such allowance has not been made in the scheduling of performance data by the manufacturer, the PIC is recommended to apply factors only to the contaminated runways.

The following should be considered when calculating the performance to land within LDA:



  1. the pressure altitude and temperature at the aerodrome;

  2. the runway surface condition and the type of runway surface;

  3. the runway slope in the direction of landing;

  4. not more than 50 % of the reported head-wind component or not less than 150 % of the reported tailwind component if not already accounted for by the manufacturers performance data; and

  5. use of the most favorable runway, in still air;

  6. use of the runway most likely to be assigned considering the probable wind speed and direction and the ground handling characteristics of the airplane, and considering other conditions such as landing aids and terrain.

Use of Minimum Equipment List(s)

The Minimum Equipment List (MEL) lists all the equipment, systems and components that must be serviceable before flight. Items that may be unserviceable which will not jeopardize the continuation of the flight, together with any additional limitations that may apply to flights with such inoperative items, are indicated in the MEL. The MEL is intended to permit operation with inoperative equipment or components for a specified time until maintenance can rectify the unserviceable items.

The MEL provides the PIC with the authority to operate the airplane with specified unserviceable equipment or components, but it must be emphasized that irrespective of the provisions of the MEL, the PIC is not obligated to operate with a particular defect or defects if in his/her opinion these defects could adversely affect the safety of the flight.

The MEL forms part of the Operations Manual Part B, Chapter “Minimum Equipment List” for each airplane type concerned, but is published as a separate document to make it easier to use.

Each MEL is based on a Master Minimum Equipment List (MMEL), developed by the Type Certificate Holder and approved by the Certification Authority. The corresponding MMEL, on which the MEL is based, must be acceptable to- and each separate MEL must be approved by- the competent authority prior to use and will not deviate from the Aircraft Flight Manual (AFM) limitations or emergency procedures or from any applicable airworthiness directive and will be no less restrictive than the MMEL.

The provisions of the MEL are applicable up until the airplane first moves under its own power, after which it is up to the PIC’s judgment whether a flight should continue when the defect becomes apparent after a flight has commenced.

All items not listed on the MEL that are related to the airworthiness of the airplane must be operational before departure.

Equipment not required for the safe operation of the airplane such as galley equipment or passenger convenience items are not listed on the MEL and are not required to be functional.


Updates of the MEL. The Manufacturer keeps the Master Minimum Equipment list up to date. The operator monitors the updates of the MMEL and if required amends his MEL with the relevant updated parts of the MMEL. After that a copy of the MEL is resend to the Competent authority.
