investigating Radar Altimeter issue while SlingLoad

[Renko]

I think there is an incorrect behaviour in the Chinook. When you do slingload the radar altimeter remains stable showing the rope lenght to the cargo.
I think this is correct in other smaller helos, but incorrect in the Chinook.

First of all the Chinook has its RadAlt sensors in the nose pointing forward (emitter and receptor) long way from the center hook. This helicopter is 30 meters long.

Then you have for the center hook a trapdoor for the crewchief, and there is a RadAlt gauge too. 
Just saw a video from the Spain Army with a F model, saying the crewchief uses that during night ops to help guide the pilot.

And If you see the D model operators manual you will find this phrase a couple of times:
"When external cargo is carried, the radar altimeter may occasionally indicate the distance between the bottom of the helicopter and the load."
It says may occasionally , not continuously.

Since I don't think it's planned to model the occasional interference of a sling load with the sensors, I think it makes sense to correct the current logic. An let the sensors work even with slingloading. This would allow the sensors to work properly.

Best regards!
