Category A: Speed less than 91 knots.
Category B: Speed 91 knots or more but less than 121 knots.
Category C: Speed 121 knots or more but less than 141 knots.
Category D: Speed 141 knots or more but less than 166 knots.
Category E: Speed 166 knots or more. (Catégories de vitesses d'approche)

5. Critical aircraft
The aircraft identified as having the most demanding operational requirements with respect to the determination of movement area dimensions, and other aerodrome physical characteristics at the aerodrome or part thereof. (Avion critique)
RDIMS

6. Fixed By Function NAVAID
An air navigation aid (NAVAID) that must be positioned in a particular location in order to provide an essential benefit for civil aviation is fixed by function. Exceptions are:
(a) Equipment shelters, junction boxes, transformers, and other appurtenances that support a fixed by function NAVAID are not fixed by function unless operational requirements require them to be located in close proximity to the NAVAID.
(b) Some NAVAIDs, such as non-directional beacons or localizers, can provide beneficial performance to civil aviation even when they are not located at their optimal location. These NAVAIDS are not fixed by function. (NAVAID fixe de par sa fonction)
RDIMS

7. Obstacle
All fixed (whether temporary or permanent) and mobile objects that are located within an area protected for the surface movement of aircraft or that project into a defined surface intended to identify obstacles or protect aircraft in flight. (Obstacle)
RDIMS

8. Obstacle Limitation Surface (OLS)
Transitional surface
Inner-transitional surface - A complex surface extending lengthwise on the runway strip that extends upwards and outwards to the outer obstacle identification surface.
Approach surface - An inclined plane preceding the threshold of a runway.
Take-off surface - An inclined plane beyond the end of the runway, or clearway if provided.

9. Obstacle Identification Surface (OIS)
A surface that is used to identify obstacles into the airspace associated with an aerodrome. Obstacle identification surfaces consist of the following:
Outer Obstacle Identification surface. A surface located in a horizontal plane above an aerodrome and the surrounding area.
Approach Identification surface. An inclined plane preceding the threshold of a runway.
RDIMS

10. Obstacle free zone (OFZ)
The airspace above the Precision Obstacle Free Zone, Approach Surface, Inner Transitional Surface, and that portion of the strip bounded by these surfaces, which is not penetrated by any obstacle, except for frangible visual NAVAIDs that need to be located in the OFZ because of their function. (Zone dégagée d'obstacles)
RDIMS

11. Private taxiway A taxiway that is not;
used for commercial passenger carrying operations, or
connected directly to a runway. (Voie de circulation privée)
RDIMS

12. Runway types
Runways intended for the operation of aircraft and categorized as follows:
Non-instrument Runway A runway intended for the operation of aircraft using visual approach procedures, or an instrument approach procedure down to a Height Above Aerodrome (HAA)/ Height Above Threshold (HAT) not lower than 500 ft.
Non-precision Runway. A runway served by visual and non-visual navigation aids that provides at least lateral guidance adequate for instrument approach procedure down to a HAA/ HAT lower than 500 ft but not lower than 250 ft, and with an approach visibility not less than ¾ SM (RVR4000).

13. Runway types (cont’d) Precision Runway
Category I - A runway served by visual and non-visual navigation aids that provide lateral and vertical guidance adequate for an instrument approach procedure down to a Height Above Threshold (HAT) lower than 250 ft but not lower than 200 ft, or with an approach visibility less than ¾ SM (RVR4000) but not less than ½ SM (RVR2600);
RDIMS

14. Runway types (cont’d) Precision Runway
Category II - A runway served by visual and non-visual navigation aids that provide lateral and vertical guidance adequate for an instrument approach procedure down to a Height Above Threshold (HAT) lower than 200 ft but not lower than 100 ft, or with an approach visibility less than ½ SM (RVR2600) but not less than ¼ SM (RVR1200);
RDIMS

15. Runway types (cont’d) Precision Runway
Category III - A runway served by visual and non-visual navigation aids that provide lateral and vertical guidance adequate for an instrument approach procedure to a Height Above Threshold (HAT) lower than 100ft or no decision height, or with an approach visibility less than ¼ SM (RVR1200) or no visibility (RVR) limit. (Types de piste)
RDIMS

16. Runway strip
A defined area, which includes the runway, and stopway where provided, intended to protect aircraft flying over it during take-off or landing operations. (Bande de piste)
RDIMS

17. (similar definition for Taxiway Safety Area)
Runway Safety Area
A defined area, within the runway strip intended to reduce the risk of damage to aircraft running off a runway. (Aire de sécurité de piste).
