Part 121 : Air Transport Operations - Carriage on Aeroplanes of more than 19 Passengers or Cargo

Subpart 8 : Aeroplane Performance Operating Limitations

121.08.2 Take-off mass limitations

 

(1) A person shall not conduct a take-off in an aeroplane if a mass of such aeroplane—
(a) exceeds MTOW specified in such aeroplane’s flight manual for the pressure altitude and ambient temperature at an aerodrome where the take-off is to be made; or
(b) exceeds landing mass specified in such aeroplane’s flight manual for a pressure altitude and an ambient temperature at a destination aerodrome or alternate aerodrome, after allowing for planned fuel consumption during a flight.

 

(2) A person shall not conduct a take-off in an aeroplane unless such an aeroplane is able, in an event of a critical engine failing or for other reasons, at any point in a take-off, either to discontinue a take-off and stop within the accelerate-stop distance available or to continue a take-off and clear all obstacles along a flight path by an adequate vertical or horizontal distance.

 

(2A) For the purposes of determining an accelerated stop distance, a PIC shall take into account a loss, if any, of runway length due to alignment of an aeroplane prior to take-off.

 

(2B) For the purpose of determining a resulting take-off obstacle accountability area, a PIC shall take into account the crosswind component and navigation accuracy.

 

(3) In the determination of a maximum take-off mass referred to in subregulation (1)—
(a) the required accelerate-stop distance shall not exceed the accelerate-stop distance available;
(b) the required take-off run shall not exceed the take-off run available; and
(c) the required take-off distance shall not exceed the take-off distance available.

 

(4) For the purposes of subregulation (2), the following factors shall be applied—
(a) pressure altitude at an aerodrome;
(b) ambient temperature;
(c) runway slope in a direction of take-off;
(d) not more than 50 % of the reported headwind component or not less than 150 % of the reported tailwind component;
(e) loss of effective take-off run available during runway alignment except where rolling take-offs are approved;
(f) where a runway condition is other than dry an appropriate penalty based upon runway condition or contaminates on a runway shall be factored into the performance calculation;
(g) MTOW of an aeroplane;
(h) specific operating procedures; and
(i) any other factor that may significantly affect aeroplane performance.
