Airspeed???

Hi,

 

Is anyone able to exceed 200 km/h indicated ? That seems to be the top speed I can get out of it but the Gazelle is capable of 260 cruise and 310 max?

 

Also, any real rotor heads can explain why the loss of lift when transitioning through etl?

The SA-342M, which is simulated in DCS does have a diffrent rotor than a standard Gazelle, more optimized towards MTOW than to top speed.

 

As you noted SA-342M will be crusing at the 180km/h-200km/h range.

Please read the manual!

 

"The SA-342M1 Gazelle uses the TURBOMECA Astazou XIV Tuboprop engine, which directly comes from the Astazou II engine, used on the Aerospatiale Alouette Helicopter. Developing up to 870 hp, this engine is perfectly fitted on the Gazelle. Considering its very lightweight, the standard helicopter version, without HOT3 and Viviane sighting system, is able to reach a VNE of 310km/h.

Unfortunately, on the SA-342M1 Viviane version, the rotor blades choice allows a more important take-off mass but decreases the Vne to 280km/h, and the helicopter will hardly reach a maximal forward flight speed of 180 to 200km/h."
