What is the speed range for the starter assisted relight envelope?

• A. Vref to Vmo
• B. Vs to Vmo
• C. Vx to Vmo
• D. Vy to Vmo

Answer: (A)

The correct answer regarding the speed range for the starter assisted relight envelope being between Vref to Vmo is accurate because it encompasses specific operational speeds that ensure safe relight procedures. Vref is the reference landing speed, which provides a margin for safe operation during critical phases such as engine relight. Vmo represents the maximum operating speed where aerodynamic and structural limits of the aircraft are maintained. This range allows for effective engine restart attempts under conditions that are safe regarding aircraft performance and engine operation. Operating within this envelope helps pilots manage their approach to relight in a manner that minimizes the risk of engine failure or stall due to excessive airspeeds or low-speed configurations that are not ideal for relights. Overall, the chosen speeds align with aerodynamic safety principles established in aviation operations, making them critical in procedures for engine relight scenarios.
