## Summary

We propose to adopt a new airworthiness directive (AD) for all Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Model Gulfstream G150 airplanes. This proposed AD was prompted by a review that determined that the runway slope and anti-ice corrections to V1 and take-off distances in the Gulfstream G150 Airplane Flight Manual (AFM) were presented in a non-conservative manner. This proposed AD would require revising the performance section of the AFM to include procedures to advise the flightcrew of certain runway slope and anti-ice corrections and take- off distance values. We are proposing this AD to prevent the use of published non-conservative data, which could result in the inability to meet the required take-off performance, with consequent hazard to safe operation during performance-limited take-off operations.
