Pilots Discuss Use of Osprey

Forum Introduction
V-22 Osprey The V-22 Osprey, an airplane that can land and take off like a helicopter, is expected to deploy to Iraq in September, although critics contend it has design flaws. Two pilots answered your questions about the aircraft.
QUESTIONS
What does the Osprey do better than other aircraft that makes it worth the cost?
How intense is the rotor downwash with respect to the expected need to swoop in and pick up ground troops?
How prevalent is "vortex ring state" in landing?
With no auto-rotation landing, what does the pilot do if both engines fail?
What happens if one engine fails?
What would the pilots do to survive a plane in vertical mode dropping like a rock?
Were helicopter problems in the past mostly due to human error?
Is it important for military operations to have one aircraft be a helicopter and airplane?
What role would the Osprey perform in Iraq?
Charles Alexander of Boise, Idaho, asks:
What role would the Osprey perform in Iraq? Does it have weapons platform capabilities? Is it a troop carrier? Just how would deployment of this expensive piece of equipment help the war effort?
ANSWERS
Lt. Col. Bianca responds:

The MV-22 is being fielded in Iraq as a medium lift requirement to replace the Marine Corps Squadrons already there. It is primarily a troop carrier, but it can also lift 4 to 5 shore tons (internally or externally) depending on conditions. The MV-22 will first take over the mission helicopter squadrons are currently doing. It will then expand its mission set to a little bit more. It will most likely have missions involving longer range or greater endurance that we currently have in theater.

What we desire most about the MV-22 in this theater "right away" is its speed. With MV-22 in theater, evacuation of the wounded will be significantly faster. MV-22 is not only significantly faster, its capable of going direct to higher level medical facilities that conventional helicopters due to its range and speed.

Jim Furman responds:

If it is to replace the Marine CH46, it would have to fly combat assaults, resupply and medical evacuations. Unless it is kept far from any real combat, which is hard to do when there is no defined FEBA (Forward Edge of the Battle Area) you would have to arm it. The Osprey cannot mount guns on the side because of the engine pylons. Therefore, the solution has been to mount a machine gun on the tailgate. This is not very practical because it will impede troop ingress and egress out the only door that they can really use. It is not logical because if you are landing in a hot (enemy fire) LZ (Landing zone), the threat is usually to the sides of the helicopter or in front of the helicopter. There is also a real hazard to friendly troops and the Osprey behind you in the LZ if the door gunner is trying to lay down suppressive fire. Lastly, the one 7.62 mm machine gun is a pretty puny defensive weapon for such a large and valuable asset as the Osprey.
