Operational factors that could affect an instrument takeoff (e.g., runway length, runway lighting, surface conditions, wind, wake turbulence, icing conditions, obstructions, available instrument approaches or alternate airports available) in the event of an emergency after takeoff.
Bottom line
Takeoff planning factors include weight and balance, airplane performance, runway length, slope and contamination, terrain and obstacles in the area, weather conditions, and pilot proficiency. Before takeoff, the pilot should consider available options if an engine failure occurs after takeoff. Those options include the preferred direction for any emergency turns to landing sites, based on the departure path, altitude, wind conditions, and terrain.
