How are aeroplane certification levels defined in CS 23.2005?

Aeroplane certification levels are: Level 1 for 0 to 1 passengers; Level 2 for 2 to 6 passengers; Level 3 for 7 to 9 passengers; and Level 4 for 10 to 19 passengers.

What are the performance level classifications for aeroplanes under CS 23.2005?

Performance levels are: Low speed for aeroplanes with a VNO or VMO ≤ 250 KCAS or a MMO ≤ 0.6; and High speed for aeroplanes with a VNO or VMO > 250 KCAS or an MMO > 0.6.

Which manoeuvres are permitted for aeroplanes not certified for aerobatics?

Aeroplanes not certified for aerobatics may be used to perform any manoeuvre incident to normal flying, including stalls (except whip stalls) and lazy eights, chandelles, and steep turns in which the angle of bank is not more than 60 degrees.

If an aeroplane has a VMO of 260 KCAS, what performance level is it classified as?

High speed, because high speed is for aeroplanes with a VNO or VMO > 250 KCAS or an MMO > 0.6.

Can an aeroplane not certified for aerobatics perform a whip stall?

No, because stalls (except whip stalls) are permitted, but whip stalls are explicitly excluded.

What is the maximum angle of bank allowed for steep turns in an aeroplane not certified for aerobatics?

The angle of bank must not be more than 60 degrees.

CS 23.2005 Certification of normal-category aeroplanes

Q: What is the maximum passenger seating configuration and maximum certified take-off mass for an aeroplane to be certified in the normal category?

The normal category applies to aeroplanes with a passenger seating configuration of 19 or less and a maximum certified take-off mass of 8 618 kg (19 000 pounds) or less.

Q: Is a 20-passenger aeroplane with a maximum take-off mass of 9,000 kg eligible for normal category certification?

No, because the normal category applies only to aeroplanes with a passenger seating configuration of 19 or less and a maximum certified take-off mass of 8 618 kg (19 000 pounds) or less.

Q: An aeroplane has a maximum seating configuration of 8 passengers. Which certification level does it fall under?

Level 3, which is for aeroplanes with a maximum seating configuration of 7 to 9 passengers.
