Hi there, I remember some time ago when flying on the classics that the Flight Crew Training Manual said the following regarding RTOs or Landings with an engine on fire, “If rejecting due to fire in windy conditions consider positioning the airplane so the fire is on the downwind side”. A word of caution applies when considering the turning of the aircraft when it is on fire. In your scenario, landing on Rwy 36 with wind 090/16 or greater, if you make an 180 turn wind will be on downwind side and survivability will be increased. But consider also that, on aircrafts without door opening assist mechanism, it will be difficult to open the door and to deploy and use slides, specially with more than 20kts of wind. Slides are tested for symmetrical and asymmetrical loads with wind speeds up to 25 kts. As Checkboard points out placing the nose into the wind will help and if winds are very strong some 20° out of the wind will be better. In your particular case Rwy 36, wind 090/16 or more and Engine 2 on fire, point the nose onto hdg 090° or 110°. This will blow flames away from fuselage and will permit full use of doors and slides on the opposite side. Time to turn the aircraft into the wind is very little and can be accommodated within the time needed to prepare the evacuation. Finally PCN or permission to make a turn on the runway doesn’t count if you are in an emergency situation.:
