For a takeoff from RWY 34L with minimum weather, what is the minimum climb rate in feet per minute required for the RENO9.FMG departure at a groundspeed of 150 knots?

The minimum climb rate required during a departure, such as the RENO9.FMG from RWY 34L in minimum weather conditions, is mainly determined by the need to ensure obstacle clearance and to comply with specific departure procedures. When a flight is departing in reduced visibility, regulations often stipulate a higher climb rate to safely navigate potential obstacles in the aircraft's flight path.

For a groundspeed of 150 knots, a climb rate of 1,200 feet per minute ensures that the aircraft maintains a safe margin above any height requirements established for the departure route. The calculation typically involves determining the required climb gradient based on the aircraft's groundspeed and converting that into a rate of ascent. In this scenario, 1,200 feet per minute is a standard requirement, striking a balance between safety and performance, ensuring that the aircraft climbs adequately while still being manageable for the pilots to execute.

This ascent rate allows pilots to adhere to regulated standards for climb performance while considering factors like weight, configuration, and the aircraft's capabilities under varied conditions. Thus, the specified climb rate is crucial for safe departure, especially under circumstances with limited visibility where the risk of encountering obstacles is higher.
