3.3.6 Front wing profiles
Front wing profiles are defined as bodywork that is contained in the volume which extends from 250mm to 950mm from the car centre plane, and within the volume defined in Article 3.3.3. They must meet the following criteria :
a) Any intersection of these profiles with any longitudinal vertical plane may contain no more than five closed sections, each of which may contain no concave radius of curvature less than 50mm. The rearmost closed section may have a ‘gurney’ type trim tab fitted to its trailing edge provided no dimension of it exceeds 10mm.
b) For the part of the profiles outboard of a plane that lies 400mm from the car centre plane :
i) The rearmost point of every closed section must be visible when viewed from below.
ii) With the exception of the rearmost closed section, the rearmost point of every closed section must not be visible when viewed from above.
iii) The normal to any point of the profiles’ surface must not subtend an angle greater than 15° to a vertical plane which is normal to the diagonal line described in Article 3.3.3(a).
c) Outboard of a plane that lies 400mm from the car centre plane the minimum distance between adjacent sections at any longitudinal vertical plane must lie between 5mm and 15mm at their closest position.
Minimal exceptions to the above geometrical criteria can occur in areas of transition close to consecutive longitudinal vertical cross sections with a different number of individual profiles. Outboard of a longitudinal plane that lies more than 400mm from the car centre plane, such changes may only be achieved by the bifurcation of a single closed section into two or more closed sections, and the method of construction of this transition is detailed below.
The area of transition will be defined by two vertical planes, which are parallel to each other, up to 20mm apart, and form an angle of no more than 20° to the car centre plane. Within this area :
d) The inboard (single) profile surface must be defined over the full span of the transition area in full compliance with Article 3.3.6.
e) The outboard profile (two or more) surfaces must be defined over the full span of the transition area in full compliance with Article 3.3.6, lie entirely within the single profile surface, and share the same overall chord.
f) Once the inboard and outboard profile surfaces have been defined, blending surfaces must be defined to join the profiles together. These surfaces must lie within the volume of the single, inboard profile surface, and entirely within the transition volume. Once these minimal transition surfaces have been defined, the original overlapping surfaces of the inboard and outboard profiles must be trimmed accordingly.
Once the front wing profiles have been defined, they must be trimmed by the virtual endplate surface defined in Article 3.3.5, and the portion of the front wing profiles outboard of that surface must be discarded. Where the front wing profiles intersect the front wing endplate, a maximum fillet radius of 10mm may be applied.

3.3.6 Front wing profiles
Front wing profiles are defined as bodywork that is contained in the volume which extends from 250mm to 950mm from the car centre plane, and within the volume defined in Article 3.3.3. They must meet the following criteria :
a) Any intersection of these profiles with any longitudinal vertical plane may contain no more than five closed sections, each of which may contain no concave radius of curvature less than 50mm.
b) For the part of the profiles outboard of a plane that lies 400mm from the car centre plane :
i) The rearmost point of every closed section must be visible when viewed from below.
ii) With the exception of the rearmost closed section, the rearmost point of every closed section must not be visible when viewed from above.
iii) The normal to any point of the profiles’ surface must not subtend an angle greater than 15° to a vertical plane which is normal to the diagonal line described in Article 3.3.3(a).
c) Outboard of a plane that lies 400mm from the car centre plane the minimum distance between adjacent sections at any longitudinal vertical plane must lie between 5mm and 15mm at their closest position.
Once the rearmost profile has been defined a single ‘gurney’ type trim tab may be fitted to its trailing edge provided no dimension in a vertical longitudinal section exceeds 10mm. This part must comply with the constraints of Article 3.3.6 (b) (iii), with the exception of its innermost and outermost 10mm (measured in a direction normal to the car centre plane) where these constraints do not apply. For clarity, gurneys that overlap with the adjustable and non- adjustable portion of the profiles (as described in Article 3.3.7) will be considered to be a single gurney, provided they satisfy all of the above criteria in the design position of the profiles.
Minimal exceptions to the above geometrical criteria can occur in areas of transition close to consecutive longitudinal vertical cross sections with a different number of individual profiles. Outboard of a longitudinal plane that lies more than 400mm from the car centre plane, such changes may only be achieved by the bifurcation of a single closed section into two or more closed sections, and the method of construction of this transition is detailed below.
The area of transition will be defined by two vertical planes, which are parallel to each other, up to 20mm apart, and form an angle of no more than 20° to the car centre plane. Within this area :
d) The inboard (single) profile surface must be defined over the full span of the transition area in full compliance with Article 3.3.6.
e) The outboard profile (two or more) surfaces must be defined over the full span of the transition area in full compliance with Article 3.3.6, lie entirely within the single profile surface, and share the same overall chord.
f) Once the inboard and outboard profile surfaces have been defined, blending surfaces must be defined to join the profiles together. These surfaces must lie within the volume of the single, inboard profile surface, and entirely within the transition volume. Once these minimal transition surfaces have been defined, the original overlapping surfaces of the inboard and outboard profiles must be trimmed accordingly.
Once the front wing profiles have been defined, they must be trimmed by the virtual endplate surface defined in Article 3.3.5, and the portion of the front wing profiles outboard of that surface must be discarded. Where the front wing profiles intersect the front wing endplate, a maximum fillet radius of 10mm may be applied.

3.3.7 Adjustability of front wing
Once the Front Wing Profiles have been defined in accordance with Article 3.3.6, a portion of up to four of the rearmost profiles may be adjustable in order to trim the front wing aerodynamic load.
For this purpose :
a) The parts of the front wing profiles that are included within the adjustable part must have no degrees of freedom between them.
b) The adjustment may only be a rotation about a fixed axis. The original position of these profiles (as defined in accordance with Article 3.3.6) must be included within the overall range of adjustment. Furthermore, the maximum deviation for any point of these profiles between the uppermost and lowermost angle of adjustment must not exceed 35mm. Minimal exceptions to the geometrical criteria for the wing profiles may be made in the junction between the adjustable and non-adjustable parts, in order to ensure the necessary level of sealing.
For the avoidance of doubt, the adjustment permitted under this Article is only allowed when the car is stationary and by the use of a tool, and in accordance with the Formula 1 Sporting Regulations.
Furthermore, any such variation of incidence maintains compliance with all of the bodywork regulations, with the exception of Articles 3.3.6 (a) and 3.3.6 (b).

3.3.7 Adjustability of front wing
Once the Front Wing Profiles have been defined in accordance with Article 3.3.6, a portion of up to four of the rearmost profiles and the gurney, may be adjustable in order to trim the front wing aerodynamic load.
For this purpose :
a) The parts of the front wing profiles that are included within the adjustable part must have no degrees of freedom between them.
b) The adjustment may only be a rotation about a fixed axis. In plan view, this axis must not subtend an angle greater than 20deg to the diagonal line described in Article 3.3.3 (a), and in front view it must not subtend an angle greater than 15deg to the horizontal plane. For the full extent of the adjustable part of the profiles outboard of a plane that lies 400mm from the car centre plane, and in any longitudinal vertical plane, this axis must lie between two vertical lines, one that passes through the forward most point of the adjustable part of the profiles in that section, and another one 30mm behind the first line.
c) The junction between the adjustable and non-adjustable parts of the profiles must be defined by one or two surfaces of revolution about the fixed axis of rotation defined in 3.3.7 b . Furthermore, any normal to these surfaces of revolution may not subtend an angle greater than 55° to a line that is normal to the car centre plane. These surfaces of revolution must also lie inboard of the virtual endplate surface defined in Article 3.3.5.
d) The original position of these profiles (as defined in accordance with Article 3.3.6) must be included within the overall range of adjustment. Furthermore, the maximum deviation for any point of these profiles between the uppermost and lowermost angle of adjustment must not exceed 35mm.
e) Minimal exceptions to the geometrical criteria of Article 3.3.6 for the wing profiles may be made in the junction between the adjustable and non-adjustable parts, in order to ensure the necessary level of sealing. Such parts must lie within 3mm from one of the two surfaces of revolution and their maximum size must be the minimum necessary amount required to achieve a 20mm overlap between the adjustable and the non-adjustable parts of the profiles over the whole range of movement.
For the avoidance of doubt, the adjustment permitted under this Article is only allowed when the car is stationary and by the use of a tool, and in accordance with the Formula 1 Sporting Regulations.
Furthermore, any such variation of incidence maintains compliance with all of the bodywork regulations, with the exception of Articles 3.3.6 (a) and 3.3.6 (b).

3.3.9 Front wing auxiliary components
For mechanical, structural or measurement reasons only, the following components will be permitted in addition to the bodywork defined in Articles 3.3.5, 3.3.6 and 3.3.8 :
a) Two brackets which define the pivot axis of the adjustable part of the front wing profile, and allow the necessary movement. These brackets should be no more than 5mm thick, and in no part more than 30mm distant from either the stationary or the adjustable part of the wing profiles. A fillet radius no greater than 2mm will be permitted where these brackets join the two profiles.
b) Slot gap separator brackets between consecutive front wing profiles, provided they are no more than 5mm thick and in no part more than 25mm distant from both of the two profiles they support in relation to each other. A fillet radius no greater than 2mm will be permitted where these brackets join the two profiles.
c) A minimal mechanism with or without a minimal fairing to contain it for the angle adjustment of part of the front wing profiles, as defined in Article 3.3.7.
d) A minimal fairing that contains a single tyre temperature sensor. The dimension of the complete tyre temperature sensor and fairing must be no greater than 30mm wide x 50mm long x 30mm high. A maximum of one sensor and fairing may be positioned on each side of the car, and may be joined to the bodywork defined in Articles 3.3.5 or 3.3.6 with a minimal support.
Should there be a requirement for any additional component to be added, a team must write specifically to the FIA with an explanation, design, and calculated aerodynamic effect, in order to get approval. Such a communication will be circulated to rival teams if deemed to cover a new aspect that had previously not been considered.

3.3.9 Front wing auxiliary components
The following components will be permitted in addition to the bodywork defined in Articles 3.3.5, 3.3.6 and 3.3.8 for primarily mechanical, structural or measurement reasons:
a) Two brackets which define the pivot axis of the adjustable part of the front wing profile, and allow the necessary movement. These brackets must:
- be in their entirety within 40mm from both the stationary and the adjustable part of the profiles over the whole range of adjustment
- be no more than 5mm thick. A fillet radius no greater than 2mm will be permitted where these brackets join the two profiles

b) Up to sixteen (in total, per side) slot gap separator brackets which connect consecutive
front wing profiles. These brackets must:
- be in their entirety within 30mm from both of the two profiles they support in relation to each other
- be no more than 5mm thick. A fillet radius no greater than 2mm will be permitted where these brackets join the two profiles
- have no dimension that exceeds 60mm
c) A mechanism with or without a fairing to contain it for the angle adjustment of part of the front wing profiles, as defined in Article 3.3.7. This mechanism and fairing must fit within a cuboid of which is 25mm wide, 60mm long and 60mm high. This cuboid may have a free orientation in space, but must intersect both the stationary and the adjustable part of the profiles for the entire range of adjustment.
d) A fairing that contains a single tyre temperature sensor. The entire fairing and sensor must:
- fit in the union between two volumes, a cuboid which is 15mm wide, 60mm long and 50mm high and a circular cylinder which has a base diameter of 30mm and a height of 60mm. The axis of the cylinder must coincide with the major axis of the one of the 15mm x 60mm faces of the cuboid.
- be symmetrical about a plane which is parallel to the 50mm x 60mm faces of the cuboid, and - intersect either the profiles defined in Article 3.3.6 or the endplate defined in Article 3.3.5. A fillet radius no greater than 5mm will be permitted along the periphery of this intersection.
Furthermore, all the components listed above must not be visible from below, with the front wing endplates defined in Article 3.3.5 and the front wing strakes defined in Article 3.3.8 removed, and must lie inboard of the virtual endplate surface defined in Article 3.3.5.
Should there be a requirement for any additional component to be added, a team must write specifically to the FIA with an explanation, design, and calculated aerodynamic effect, in order to get approval. Such a communication will be circulated to rival teams if deemed to cover a new aspect that had previously not been considered.
