Herman Posada sits at the controls and flies his airplane. But he's not in the airplane! He's at a ground station miles away, using a joystick and video monitors to control the vehicle.

Herman is a NASA research pilot who flies unmanned aerial vehicles. These remotely piloted, full-scale aircraft are used more and more for research into advanced aeronautics systems and for capturing images and data in dangerous conditions such as wildfires or hurricanes.

NASA's Ikhana, an unmanned Predator B modified for non-military missions, carries instruments for environmental Earth science studies and is used for advanced aircraft systems research and technology development. The Global Hawk unmanned aircraft has been very busy this hurricane season, flown by Herman and another pilot into and above hurricanes to collect data.

On Thursday, September 23, Herman answered your questions in both English and Spanish about what it's like to fly these unique, full-scale aircraft. A transcript of the chat will be posted soon on this page.

Akarsh_Valsan: How can unmanned aerial systems be useful in the field of environment?

Herman: We are doing Earth science missions such as studying hurricanes and wildfires. An unmanned aircraft can often go to dangerous places where manned aircraft can't. \\ Estamos estudiando la ciencia de huracanes y encendios. Un avion sin piloto puede volar a lugares mas peligrosos que un avion con piloto no puede.

Tclopper: Do you have to account for magnetic declination when navigating the aircraft?

Herman: Yes, we do account for magnetic declination. \\ Si tenemos cuentas para declination magnetica.

Akarsh_Valsan: What do you feel when you control unmanned aerial vehicles from the Ground Control Station?

Herman: Obviously, I feel nothing since I am flying from the ground, but I put myself in the plane and treat it as if I was in the airplane. \\ Obiamente, no siento nada porque estoy in la tierra, pero me siento como si estuviera en el avion.

Akarsh_Valsan: Which was your favourite unmanned aircraft?

Herman: My favorite UAV is Ikhana since I have most of my experience in that plane. \\ Mi favorito es Ikhana porque en el tengo mas experiencia.

Achordj: How far does the aerial plane fly from you?

Herman: We can fly anywhere in the world. I can be in California and the plane can be thousands of miles away. \\ Podemos volar a cualquier lugar en el mundo, yo puedo estar en California y el avion puede estar a miles the kilometros.

Rodrigo: Para que tipo de misiones se utilizan los vuelos no tripulados? Qué ventajas tienen con respecto a los vuelos regulares?

Herman: Los utilizamos para volar a lugares que son muy peligros donde aviones regulares no pueden volar. \\ We utilize them to fly to dangerous places where regular airplanes can't fly.

Amustain: What are the dimensions of the Global Hawk? How long is the wingspan?

Herman: The Global Hawk is bigger than you think. The dimensions are 44ft long, 116 ft wing span, 15ft tall and 25600 lbs at takeoff. \\ El avion Global Hawk es mas grande de lo que imaginas. Las dimensiones son 44ft largo, 116 ft alas, 15ft alto y 25600 libras a la hora de el despegue.

Herman: Es posible en el futuro, pero ahora no es posible porque no tenemos las regulaciones. \\ It will be possible in the future, but not for now, we don't have the regulations.

Achordj: What would you do if the computer crashes? Are you still able to control the plane?

Herman: The unmanned system has many redundancies. We have backups to the backups. \\ El avion no tripulado tiene muchas redondancias. No es problema.

Achordj: How are the planes powered?

Herman: Global Hawk uses jet fuel for its jet engine. Ikhana uses jet fuel for its turboprop.\\ Global Hawk usa especial gasolina para su turbina. Ikhana usa combustible para la turbina con elis.

Akarsh_Valsan: Have you ever felt any discomforts when you were controlling unmanned aircrafts?

Herman: Yes, funny you mentioned that; I sometimes "feel" turbulence in the UAV even though I am not in the vehicle. \\ Si, es gracioso que menciones eso; algunas veces "siento" turbulancia en el avion aun cuando yo no estoy en avion sin tripulacion.
