CAP 789 had some guidance as follows, I have emphasised the relevant part:
2 Actions that Should be Taken in the Event of an Uncontrolled Aeroplane Fire on the Ground
2.1 Fire During Take-Off
2.1.1 An uncontrolled aeroplane fire, often involving an engine on one side of the aeroplane, may result in a rejected take-off followed by an evacuation. The flight crew should include in their pre-departure brief the required actions in the event of a fire before V1, taking into account all the prevailing circumstances. The main priority must be to stop the aeroplane safely on the runway. An automatic rejected take-off system, where fitted, is usually the best way of achieving this.
2.1.2 Where it is possible, at an appropriate speed before stopping, a turn towards the side with the fire in headwind conditions and away from it in tailwind conditions is recommended, so as to place the fire downwind of the fuselage, unless other risk factors are more significant. Other risks increase with aeroplane size, and crews of larger aircraft should consider, for example, the risks of turning at too high a speed or placing the fire outside the paved surface with possible restriction of access for Rescue and Fire Fighting Services (RFFS).
2.1.3 If turns are recommended, then simulator training and checking in rejected take-offs from close to V1 due to fire should be required at an appropriate frequency. The conditions simulated should include crosswinds (with a tailwind component on occasions), and occasionally a wet runway.
2.2 Fire During Other Ground Operations
2.2.1 Many of the factors that apply to fires during take-off will apply to fires during other ground operations. However, turning to take the wind into consideration may be easier during taxiing as speeds are lower and there may be more time. There may be occasions where turning is not possible, for example whilst parked. In this case the main priority will be, as always, the safety of passengers and crew.
