Section 3A—General Guidelines<br />

Chapter 3<br />

A-10 DEMONSTRATION MANEUVERS<br />

3.1. General. Maneuvers described in this chapter will be used for training and for A-10 aerial demonstrations.<br />

The demonstration sequence is designed so each maneuver is normally performed in the same<br />

direction with respect to the crowd line. As a result, the show is always oriented the same way from the<br />

spectators' point of view. The only exception to this is when wind direction and velocity make it advantageous<br />

to change the direction of the slow speed pass. In this case, the remaining maneuvers are flown in<br />

the opposite direction. Abnormal Procedures are written for each maneuver. If the entry conditions are not<br />

met for any maneuver, a wings-level pass will be flown and the pilot will transition to the next maneuver.<br />

Demonstration pilots will transmit parameters prior to initiating the descending portion of vertical<br />

pull-throughs and Vertical Reposition maneuvers. These calls will be made anytime between the point the<br />

pilot climbs through the minimum over-the-top (OTT) altitude designated in each maneuver description<br />

up to the point the pilot reaches apex altitude. Ground safety observer will monitor demonstration pilot<br />

altitude and airspeed radio calls and direct an abort when parameter limits are exceeded.<br />

3.2. Aircraft C onfiguration and Fuel Requirements. Aircraft configuration for all demonstrations will<br />

be clean. Each demonstration uses approximately 1,000 pounds of fuel. Optimum performance is<br />

obtained when fuel load is 3,500 pounds; however, the demonstration can be safely accomplished with a<br />

higher fuel load as long as the wing tanks are empty. The minimum fuel to start the show is 2,500 pounds.<br />

3.3. Airspeed and G-Limits. The A-10 demonstration is flown at max power except when slowing to<br />

configure for the slow speed pass or slowing to configure for the minimum run landing. The maximum<br />

Target G for this demonstration profile is 6.0 Gs. This does not preclude a momentary increase in G for<br />

safety considerations.<br />

3.4. Show line Restrictions. The majority of the A-10 demonstration will be flown on the 1,500-foot<br />

show line in reference to the distance from the crowd. Non-aerobatic maneuvers (less than 90 degrees of<br />

bank) may be flown on the 500-foot show line.<br />

3.5. Airspace and Runway Requirements. Required airspace for the A-10 is 7,000 feet AGL vertically<br />

and normally a five-mile radius from show center horizontally. The minimum dimensions of the aerobatic<br />

box are 2,700 feet wide, 4,000 feet long, and 7,000 feet AGL (high show). Minimum runway length is<br />

5,000 feet x 75 feet. The runway, taxiway, and parking area must be stressed for a 35,000-pound aircraft<br />

with single wheel type landing gear.<br />

3.6. Weather Requirements. Weather PARAMETER LIMITS for the high profile are a ceiling of at<br />

least 4,000 feet, 3 miles ground and 5 miles in-flight visibility with a discernible horizon. Ceiling required<br />

for the low profile is 2,500 feet. Maneuvers will be planned to maintain VMC throughout the show<br />

sequence.<br />

3.7. Repositioning Turn.
