THE AIRCRAFT.

The A-10C is a single-seat close air support aircraft (Figure 1-1and Figure 1-2) manufactured by Fairchild Republic Company,Farmingdale, New York. The aircraft is a low wing, low tailconfiguration with two high bypass turbo fan engines installedin nacelles mounted on pylons extending from the aft fuselage.Twin vertical stabilizers are mounted on the outboard tips of thehorizontal tail. The tricycle forward retracting landing gear isequipped with an anti-skid system and a steerable nose-wheel.The nose gear is installed to the right of the aircraft centerline topermit near-centerline gunfire. The nose gear retracts fully intothe fuselage while the main gears partially retract into stream-lined pods in the wings. A titanium armor installation surroundsthe cockpit. The primary flight controls are equipped with ar-tificial feel devices to simulate aerodynamic feel. The elevatorand aileron controls split into redundant separate systems beforeleaving the armor protection. The controls are powered by twoindependent hydraulic systems, either of which has the capa-bility of controlling the airplane. If both hydraulic systems fail,

the airplane can be flown using a manual reversion system. Theailerons consist of an upper and lower panel that become speedbrakes when opened. The windshield front panel is resistant tosmall arms fire and birds. The windshield side panels are resis-tant to spall spray caused by penetrations. The fuselage fuel cellsumps are self-sealing on the lower portion and tear resistant onthe upper portion. The cells are filled with a flexible foam toprevent fuel tank explosion. Single point ground refueling andengine feed lines are self-sealing. The escape system providesa zero/zero capability (zero velocity and zero pitch and roll at-titude) either with the canopy removed or through the canopy.The armament system includes a high fire rate 30mm seven-bar-rel gun with ammunition stored in a drum. A variety of stores iscarried on 11 pylons, four on each wing and three on the fuse-lage.

AIRCRAFT DIMENSIONS.The overall dimensions of the aircraft under normal conditionsof gross weight, tire and strut inflation are as follows:

Overall length 53 ft 4 in.

Wing span 57 ft 6 in.

Horizontal tail span 18 ft 10 in.

Height to top of fin 14 ft 8 in.

Wheel base 17 ft 9 in.

Wheel tread 17 ft 3 in.

Refer to Section II for minimum turning radius and ground clear-ance dimensions.

AIRCRAFT GROSS WEIGHT.The aircraft operating weight is approximately 28,000 pounds.This weight includes pilot, gun (full of ammunition), 11 emptypylons, oil, windshield wash, and unusable fuel. Refer to SectionV for gross weight limits. For specific aircraft weight, refer toWeight and Balance Data, TO 1-1B-40.

ENGINES.The aircraft is powered by two General Electric TF34-GE-100Aengines (Figure 1-4). Sea level, standard day, static thrust foran installed engine is approximately 8,900 pounds at maximumthrust. The engine incorporates a single-stage bypass fan and a14-stage axial flow compressor. Bypass air produces over 85%of engine thrust. Therefore, engine fan speed is the best indica-tion of thrust. Variable inlet guide vanes automatically modulatethroughout the engine operating range. An accessory gearboxdrives a hydraulic pump, fuel pump and fuel control, oil pump,and an electric generator. An air bleed for aircraft systems is pro-vided. Engine acceleration time from IDLE to MAX thrust willbe approximately 10 seconds at sea level. Engine thrust droopresults from differential expansion of the engine turbines andcasings during transients from low to high thrust operation. Theduration and extent of the thrust droop is dependent upon therate/range of throttle movement.

ENGINE THRUST DROOP.During turbine engine operation, heat expands the rotatingand stationary components to normal operating dimensionsand clearances. Engine thrust droop results from differentialexpansion of the engine turbines and casings during transientsfrom low to high thrust operation. The duration and extent ofthe thrust droop is dependent upon the rate/range of throttle

movement. Thrust droop is decreased if the engines have beenidling for a period of time. Thrust droop is further decreased ifthe engines have been run up before takeoff. An example of theworst condition would be a scramble takeoff where takeoff isaccomplished shortly after engine start. Maximum droop occursapproximately 10 seconds after the throttle is advanced fromIDLE to MAX. After approximately 4 minutes of operation atMAX thrust, power output returns to normal. Elimination ofthrust droop can be observed on the engine fan speed indicator.Thrust will increase as fan speed increases.

ENGINE CORE LOCK.Engine core lock results when an engine is shut down because itsrotating and stationary components do not contract at the samerates due to differences in material properties and differing ex-posure to cooling air. Temporary losses of clearances occur untilthe temperatures of the components reach equilibrium. Becauseof this characteristic, turbine engine shutdown procedures in-clude operation for several minutes at a lower power setting topermit internal temperatures and clearances to stabilize.

Flameouts at high power and/or high altitude conditions produceeven greater thermal distress because internal temperatures arehottest at high power settings and the external air is colder athigh altitudes. A sudden engine shutdown under these condi-tions will cause increased thermal shock exacerbating the loss ofcomponent clearance and alignment. Once core rotation stops,binding will prevent core rotation from resuming during subse-quent APU assisted restart attempts.

Engine failure at high power and/or high altitudemay result in engine core lock, preventing sub-sequent restart.

TURBINE ENGINE MONITORING SYSTEM(TEMS).The TEMS provides a means for supporting the on-conditionmaintenance concept for the TF34-100A engine installed on theA-10C aircraft. Information is provided to the system ElectronicProcessor Unit (EPU) automatically whenever the engine is op-erated. If any engine operation limit is exceeded, or when theTEMS DATA switch is depressed, a frame of data is recorded.An overlimits event will be displayed on the umbilical displayunit (UDU), located in the nosewheel well. This data is providedin code form in order to determine engine condition. The codesare provided in Figure 2-9.

TO 1A-10C-1

The IEPU is a form, fit, function replacement on selectA-10C aircraft for the existing EPU. The IEPU monitors engineand airframe mounted sensors and monitors, via the aircraft1553 Avionics #1 data bus, aircraft performance parameters.The IEPU OFP determines and records aircraft structural eventsthat are retrieved for later analysis. Engine related performanceand event data is retrieved and processed by the ComprehensiveEngine and Trending Acquisition Database (CETADS) system.The IEPU converts analog engine and airframe data into digitaldata and processes MIL-STD-1553B Inertial Navigation Sys-tem data, compares the processed data with established softwarelimits, identifies out-of-limit parameters, and records structuralloads as software requirements dictate. Recent enhancementsto the IEPU OFP provides MIL-STD-1553B Remote Terminal(RT) capabilities for uploading OFP releases from the DataTransfer Cartridge (DTC) and downloading ADR collecteddata to the Portable Automated Test Station (PATS) groundsupport equipment and software. PATS is a portable computersystem that utilizes an Operational Test Program (OTP) thatprovides diagnostic and support software for the A10 Avionicsand Weapons computer systems. In addition, the IEPU providesRS-232 Serial communication to a commercial off the shelf

(COTS) laptop computer system operating in a Windows XPor newer operating system (OS). The OS operates an A-10unique set of programs that provides operational and diagnosticsupport for the TEMS and ADR system.

The IEPU equipped aircraft displays IEPU status annun-ciations on the CDU ("IEPU FULL", "IEPU FAIL", and "IEPUNOT READY"). These annunciate the TEMS/ADR system sta-tus and the need to download TEMS and ADR data prior tonext flight. IEPU system information is accessed from page 3of the CDU SYS page. Access to MX Pages allows viewing ofthe 1553 communication, execute Built In Test (BIT), initiationof ADR data download, and viewing of the IEPU health status.

ENGINE OIL SYSTEM.The engine oil system is self-contained and all the oil suppliedis used for lubrication and cooling. Usable oil capacity is 5.6quarts, and maximum oil consumption is 0.5 pint/hr. An oil pres-sure indicator and an independent light on the caution light panelmonitor oil pressure of each engine. Oil grade and specificationto be used are covered in the servicing diagram, Figure 1-204.

Figure 1-4. TF-34 Engine

Engine Oil Pressure Indicators.An oil pressure indicator (41, Figure FO-1) is provided for eachengine. They indicate oil pressure in psi, and are powered by the26 V instrument transformer bus.

Engine Oil Pressure Caution Lights.An engine oil pressure caution light (independent of the oil pres-sure indicators) (Figure 1-158), on the caution light panel, isprovided for each engine. The lights are placarded L-ENG OILPRESS and R-ENG OIL PRESS and will come on if the pres-sure is less than 34 to 39 psi.

ENGINE FUEL SYSTEM.The engine fuel system (Figure FO-4) provides fuel required forcombustion, controls engine variable geometry actuation, andprovides engine oil cooling. Fuel is supplied to the engine fuelpumps, where it is pressurized and directed to the fuel control.From the fuel control, metered fuel passes through the engineoil cooler to the distribution valve.

Engine Fuel Control.The engine fuel control (Figure FO-4) is a hydro-mechanicaltype which modulates fuel flow to maintain a constant corespeed as called for by throttle position. An electrical control

unit regulates fuel flow at maximum power to maintain Inter-stage Turbine Temperature (ITT) limits. In the event of an ITTcontrol unit electrical failure, the system can be disabled withthe engine fuel flow switch. In this mode, the engine will bespeed-controlled throughout the entire range of operation, re-quiring monitoring to prevent engine over-temperature.

The fuel control also prevents compressor discharge pressurefrom exceeding structural limits of the compressor. At sea levelstatic, this limit is normally encountered at maximum powerwhen engine inlet temperature is 0F or colder. The limit canalso be encountered on a standard day at sea level above approx-imately 330 knots. In this case it will not be possible to obtainrated ITT. The fuel control automatically controls the position ofthe compressor inlet guide vanes and the first five stator stagesto prevent compressor stall. The engine fuel control does not re-quire electrical power, but the ITT control unit is powered bythe auxiliary AC essential bus.

Engine Fuel Flow Indicators.A fuel flow indicator (43, Figure FO-1) is provided for eachengine. They show fuel flow in pounds per hour. The indicatorsare powered by the right AC bus.

TO 1A-10C-1

Engine Fuel Flow Switches.Two engine fuel flow switches (Figure 1-5), one for each engine,are located on the engine control panel. These switches are plac-arded ENG FUEL FLOW L and R and each switch has two po-sitions, placarded NORM and OVERRIDE. With the switch inNORM, the engine fuel flow is scheduled on the basis of throttleposition and limited to the maximum power trim setting by theITT amplifier.

OVERRIDE will provide up to a 15% increase in thrust and anincrease in SERC of up to 300 FPM. The amount of additionalSERC is at a maximum between 15C and 35C for low takeoffspeeds. If the engine core temperature is limited by the ITT am-plifier limitation then the additional thrust will be available dueto OVERRIDE beginning at an ambient temperature of about-10C.

In the event of an ITT amplifier failure, the temperature con-trol system can be deactivated by placing the appropriate switchin OVERRIDE. When this is done, the engine will be speedcontrolled by the throttle position alone. Selection of OVER-RIDE when ITT is below the maximum power trim setting willproduce no change in engine operation. The engine fuel flowswitches are powered by the auxiliary AC essential bus.

THROTTLES.Amechanical throttle (Figure 1-5) controls the operation of eachengine. Each throttle has three positive stop positions placarded

OFF, IDLE, and MAX. To move from OFF to IDLE, the throttleis raised and moved forward to the first stop position. To moveto OFF the throttle is retarded to the IDLE stop, then raised andmoved aft to OFF. The DC fuel pump is energized when eitherthrottle is positioned to IDLE or above, and there is no pressurefrom the left main tank boost pump.When the throttle is at IDLEstop, the following actions take place provided engine core rpmis below 56%, and electrical power and an air source are avail-able.

ATS valve opens causing the ENG START CYCLE light tocome on

ECS shutoff valve closes

Both engine bleed air shutoff valves open

Ignition is supplied to the engine

Fuel is supplied when engine rotation starts

DC fuel pump is energized if there is no fuel pressure fromthe left main tank boost pump.

Engine speed is normally controlled by the throttle. Under cer-tain flight conditions, the engine fuel control overrides the throt-tle to protect the engine from overtemperature, overpressure,and compressor stall.

Switches and controls located on the throttle are shown on Fig-ure 1-5. The speed brake switch, along with engine throttles andthe landing gear handle are coupled with logic in the IntegratedFlight and Fire Control Computer (IFFCC) which enables thespeed brake warning functions. The speed brake warning is afunction of throttle position, not engine rpm. The Speed BrakeWarning System logic is enabled based on the throttle at MAX.

Throttle Friction Control.Throttle friction for both throttles is controlled by means of thefriction control located on the throttle quadrant (Figure 1-5).

ENGINE IGNITION SYSTEM.Ignition is supplied by two ignitors in each engine. The ignitionignitors are powered by the AC essential bus and actuated byDC powered relays. The ignitor circuits are protected by twoENG IGNITOR (L/R-1 and L/R-2) circuit breakers. Each circuitbreaker protects an ignition circuit in each engine; therefore, tototally disable the ignition circuit to one engine, it is necessaryto open both c
