(See HIAPER Capabilities vs. Those of Current NSF Fleet)

If you responded to Question C-3 above, please base your answers to the following questions on the aircraft capabilities and features needed to accomplish your prospective research study.

If you didn't respond to Question C-3, please base your answers on what you believe are the specific aircraft attributes most needed by the geosciences community at large.

Please keep in mind that no aircraft can do "maximum everything" at the same time; e.g., maximum altitude and range cannot generally be achieved with maximum payload.

For each of Questions 1-7 below, please click the boxes that most closely corresponds to your (or the community's) needs.

Example: If you require an altitude range between 45,000 and 50,000 ft, your answers should be marked as follows:

	Not Needed	Desirable but Not Critical	Critically Important
>= 20,000 ft
>= 30,000 ft
>= 40,000 ft
>= 45,000 ft
>= 50,000 ft
>= 55,000 ft

Please keep your requirements as realistic as possible.

1. Maximum Altitude:

(Maximum certified altitude in feet, maintained for at least one hour during flight)

	Not Needed	Desirable but Not Critical	Critically Important
>= 20,000 ft
>= 30,000 ft
>= 40,000 ft
>= 45,000 ft
>= 50,000 ft
>= 55,000 ft

2. Maximum Range:

(Maximum statute miles that can be flown before landing, maintaining required IFR fuel reserves)

	Not Needed	Desirable but Not Critical	Critically Important
>= 2,000 mi
>= 3,000 mi
>= 4,000 mi
>= 5,000 mi
>= 6,000 mi
>= 7,000 mi
>= 8,000 mi

3. Maximum Endurance:

(Maximum hours that can be flown before landing, maintaining required IFR fuel reserves)

	Not Needed	Desirable but Not Critical	Critically Important
>= 6 hrs
>= 8 hrs
>= 10 hrs
>= 12 hrs
>= 14 hrs
>= 16 hrs

4. Scientific Payload (Full Fuel):

(Weight of scientific payload including scientific instruments, scientific personnel, and about 1,000 pounds of data systems and other scientific infrastructure, assuming a full fuel load and thus maximum range and endurance)

	Not Needed	Desirable but Not Critical	Critically Important
>= 2,000 lb
>= 4,000 lb
>= 6,000 lb
>= 8,000 lb
>= 10,000 lb

5. Maximum Scientific Payload (Reduced Fuel):

(Maximum weight of scientific payload including scientific instruments, scientific personnel, and about 1,000 pounds of data systems and other scientific infrastructure, assuming a reduced fuel load and thus reduced range and endurance; typically this reduction in fuel, range, and endurance is of order 20-30%)

	Not Needed	Desirable but Not Critical	Critically Important
>= 5,000 lb
>= 10,000 lb
>= 15,000 lb
>= 20,000 lb
>= 25,000 lb

6. Cabin Floor Area:

(Area of cabin floor available for scientific payload; examples -- King Air B200T, 75 ft²; typical mid-sized jet, 300 ft²; C-130, 415 ft²; Electra, 628 ft²; typical airliner, 800 ft²)

	Not Needed	Desirable but Not Critical	Critically Important
>= 100 ft²
>= 200 ft²
>= 300 ft²
>= 400 ft²
>= 500 ft²
>= 600 ft²

7. Most Important Aircraft Attributes:

(Please rate the foregoing aircraft attributes according to importance)

	Least Important	Important	Most Important
Maximum Altitude
Maximum Range
Maximum Endurance
Maximum Payload (full fuel)
Maximum Payload (reduced fuel)
Maximum Cabin Floor Area
