RAZAIR‐A1‐METRO‐III‐AFM‐001 THROTTLES The position of the throttle levers obstructs the vision of several gauges located behind them. This impairment works for both the pilot and copilot positions. There is a visibility control hot‐spot that will hide the throttle levers while the left mouse button is pressed. The throttles will automatically become visible as soon as the button is released. SPEED LEVERS The speed levers position prevents access to the engine SYNCROPHASER Switch and makes more difficult reading certain gauges. Like the throttle levers, there is a visibility control hot‐spot that will hide/reveal these levers. Unlike the throttle hot‐spot, the levers will remain hidden until you either click on the hot‐spot again or on the syncrophaser switch. No. 1 Hot spot hide the throttle levers while the mouse button is pressed. No. 2 Hot spot toggles the speed levers visibility. v ...

RAZAIR‐A1‐METRO‐III‐AFM‐001 FLIGHT INSTRUMENTS There are two sets of flight instruments for both the Pilot and the Copilot. They both work with the Static Pressure and are not subject to failure in the event of losing electric power. If the alternate static pressure source is selected, the Copilot’s flight instruments become inoperational. Airspeed Indicator: The airspeed indicator displays the aircraft speed in Knots. It has the following elements: 1. A plain needle that indicates current aircraft speed. 2. A stripped needle that indicates maximum airspeed based on aircraft altitude. 3. Three thumb indicators that rotate to display: White: Minimum speed for aircraft control. b. Yellow: Minimum speed for safe climbing. Blue: Maximum speed for landing gear operation. The maximum operational speed up to 17,800 feet is 246 Knots. Above that altitude the maximum operational speed will be the following: Altitude Knots 18,000 245 20,000 235 23,000 221 Fig. 4 Airspeed Indicator 26,000 208 ...

RAZAIR‐A1‐METRO‐III‐AFM‐001 STALL AVOIDANCE SYSTEM (SAS) The Metroliner III is equipped with a stall avoidance system (SAS) which is armed at liftoff and disarmed as speed increases. Fig. 11 SAS Test Overhead Panel. Fig. 10 SAS Gauge. Fig. 12 SAS ON/OFF Switches Fig. 13 SAS Servo Switch 1‐7 ...
Page 19
RAZAIR‐A1‐METRO‐III‐AFM‐001 The SAS provides a visual warning when the aircraft airspeed is insufficient and it is about to enter into a stall condition. The SAS System must be in operation for flight. There are two SAS sensors, one for each pitot tube vane,and yellow SAS L and SAS R lights will illuminate when they are enabled for operation. The SAS system operates at airspeeds below 140 KIAS, the SAS L & SAS R lights will illuminate indicating that the system is armed. At above 140 KIAS the lights turn off indicating that the system is enabled but not operational. During operation, the gauge needle will approach the red zone as the airspeed decreases and the aircraft approaches a stall condition. The system is operational when the SAS SERVO switch and the SAS L and SAS R are all in their ON position. If the SAS SERVO switch is in the OFF position (default) a SAS SERVO light will illuminate in the annunciator panel. SAS L FAIL and SAS R FAIL yellow lights will illuminate if either SAS L or SAS R switch is in the OFF position. Under low ambient temperature conditions place the PITOT HEAT L and R switches in the PITOT & SAS HEAT position to prevent icing in the SAS vanes. A green SAS DEICE light will illuminate indicating that SAS heat has been selected. NOTE The SAS indicator is not certified for use as an in‐flight approach ...

RAZAIR‐A1‐METRO‐III‐AFM‐001 Battery voltage may be monitored by selecting the appropriate voltmeter switch position. The voltmeter and selector switch are located on the pilot´s side console (Fig 22). Fig. 22 Voltage selector and meter. The temperature of the batteries is monitored by an indicator and two switches (fig 23). The indicator contains a temperature meter for each battery (fig 23‐5), an amber WARM light (fig 23‐4), which illuminates if either battery temperature exceeds 120ºF, and a red HOT light (fig 23‐3) which illuminates if either battery exceeds 150ºF. ...
Page 23
RAZAIR‐A1‐METRO‐III‐AFM‐001 AC POWER AC electrical power is supplied by single‐phase inverters. Two inverters are installed but only one is used at a time. The inverter selector switch position determines which one is used. The inverters produce 115 volt and 26 volt AC power. Fig. 25 AC power voltmeter. The AC warning and monitoring system includes a bus selectable voltmeter on the left console (Fig 25) and two bus failure warning lights on the annunciator panel. The AC voltmeter can be selected to monitor either the left or the right 115 volt bus. If power to either 115 volt bus is lost, the respective AC BUS warning light illuminates. Illumination of both warning lights is usually an indication of inverter failure and the other inverter should be selected. POWER DISTRIBUTION Aircraft power is distributed through three DC and four AC busses. DC power is distributed through the Left Essential Bus (LEB), the Right Essential Bus (REB) and the Non‐Essential Bus (NEB). Both the LEB and RB are limited to 225 amperes while the NEB is limited to 150 amperes. The LEB is located in the left console. The REB and NEB are located in the right console. Each bus is connected to the distribution system with the bus tie switch mounted on the respective console (Figures 26 and 27). ...
RAZAIR‐A1‐METRO‐III‐AFM‐001 Fig. 27 Right Essential Bus Transfer switches. Fig. 26 Left Essential Bus Transfer switches Additionally either the LEB or REB provides power to the inverters to produce AC power. DC electrical power for control and operation of the No. 1 inverter is supplied by the LEB. The REB supplies the No. 2 inverter. The No. 1 inverter supplies power to the left 115‐VAC and left 26‐VAC busses while the No. 2 inverter supplies the right 115‐VAC and right26‐VAC busses. The 115‐VAC busses re connected through a circuit breaker as well as the 26‐ VAC busses. Consequently either inverter provides power to all four AC busses. NOTE Many of the aircraft’s gauges and instruments depend on electrical power. If one of them is not working check the electrical power switches to and meters for any power problem. MASTER WARNING SYSTEM The master warning system consists of an annunciator panel, a valve position annunciator panel and various other lights. Most lights are located on the annunciator panel. An illuminated light alerts the pilot to a system malfunction (red), a system operating parameter (amber), or a system normal operating condition (green). When a light illuminates, the pilot should follow the approved checklist procedure. Fig. 28 Annunciator Panel. 1‐13 ...

RAZAIR‐A1‐METRO‐III‐AFM‐001 ENGINE INSTRUMENTS AND CONTROLS The Metro III is powered by two turboprop engines driving four‐blade constant speed propellers. The propellers include full‐feathering and reversing capabilities. The engines are lightweight, fixed‐shaft turboprops manufactured by Honeywell, previously Garret AiResearch, and are designated TPE‐331. The engines incorporate a factory‐installed alcohol‐water injection system (AWI). The TPE‐331 is dry‐rated at 1,000 shp for takeoff and continuous operation. It is wet‐rated at 1,100 shp for a maximum of five minutes from the start of takeoff roll.

The speed switching functions of the SRL include: 1. Automatic control of the start sequence from 10% to 60% rpm, 2. SRL EGT computation above 80% rpm, and 3. Enabling CAWI operation and EGT temperature limiting above 90% rpm. The automatic start fuel enrichment modulates the start fuel enrichment valve to provide an appropriate amount of fuel during the start. The SRL EGT computation results in an indicated EGT with a single maximum EGT of 650 C for all operations. Fig. 42 SRL Control Panel. Fig. 43 SRL Control Panel Location. 1‐22 ...
RAZAIR‐A1‐METRO‐III‐AFM‐001 OIL SYSTEM The engine oil system provides for cooling and lubrication of the main engine bearings and the reduction gear. In addition to these functions the engine oil system supplies oil for propeller control, negative torque sensing (NTS) and the unfeathering pump. If oil pressure drops below 40 PSI the appropriate L or R OIL PRESSURE warning light in the annunciator panel will illuminate. ...

RAZAIR‐A1‐METRO‐III‐AFM‐001 Fig. 44 Engine START and STOP Buttons. Fig. 45 ENGINE STOP AND FEATHER Controls. ENGINE TEMPERATURE MONITORING SYSTEM An EGT gauge is provided for each engine for engine temperature monitoring (Figure 33). Below 80% rpm, compensated EGT is displayed on the EGT indicators. Above 80% rpm, a computed EGT is displayed. Below 80% rpm, the engine temperature signal proceeds to the EGT gauge without modification. Above 80% rpm, the engine temperature signal is sent to the SRL for compensation. The computed EGT shows the pilot how close the engine is to the maximum allowable. The maximum permissible computed EGT is 650 C for all operations except starting. Display of EGT values for below 80% rpm and computed EGT values for operations above 80% rpm is controlled automatically by the SRL‐Autostart computer. Two SRL ΔP/P switches (Figure 42) are provided for SRL activation. Amber lights marked “L SRL OFF” and “R SRL OFF”, located on the annunciator panel, advise the pilot when raw EGT is displayed on the EGT gauge or when the SRL computer is OFF. The SRL OFF light is normally illuminated below 805 rpm; if a SRL OFF light is illuminated when rpm is over 80% a malfunction is indicated. TEMPERATURE LIMITER SYSTEM The system consists of a temperature limiter and a fuel bypass valve. The system functions automatically to limit EGT to C by opening the fuel bypass valve and bypassing metered fuel back to the fuel pump. The temperature limiter is integrated with the SRL computer. It is armed whenever the SRL switch is in the NORM (center) position and rpm is above 90%. The system prevents EGT from exceeding the SRL value of 650 C. ...
Page 36
RAZAIR‐A1‐METRO‐III‐AFM‐001 WARNING Do not test the temperature limiter in flight. Engine flameout will result. ENGINE TORQUE MONITORING SYSTEM The torque‐measuring system monitors the twisting force being applied to the propeller through the reduction gear. The signal is sent to the torque indicator (Figure 34) in the cockpit. IGNITION SYSTEM The ignition system is a high‐energy type consisted of an engine‐mounted ignition exciter and two igniter plugs located in the combustion chamber. An independent ignition system is provided for each engine. Ignition operation is indicated by amber lights located below the EGT gauges (Figure 40). The associated light is on whenever power is applied to the ignition exciter. Fig. 47 Ignition System Switches Location. Fig. 46 Ignition System Switches The ignition system is controlled by two switches on the left console labeled AUTO/CONT IGNITION. The AUTO position (default position) allows the SRL‐Autostart computer to control ignition during start. An additional feature of the AUTO position is that it energizes the ignition if the negative torque sensing (NTS) system is activated. Engine failure or flameout permits the propeller to drive the engine (negative torque), causing the ignition to be energized as long as the ...
Page 37
RAZAIR‐A1‐METRO‐III‐AFM‐001 PROPELLERS Each engine drives a four‐blade, constant‐speed propeller. The propellers incorporate full feather and reverse capabilities, in addition to Beta mode control for ground operation. Propeller start locks are provided to maintain minimum blade angle to reduce propeller drag during engine start. The propellers are normally controlled by the interaction of the power (throttle) levers, speed levers and the propellers STOP AND FEATHER controls, which are used only under abnormal or emergency conditions. A propeller is onspeed when the actual rpm equals the selected rpm. Underspeed exists when the actual rpm is less than the selected rpm. Overspeed exists when the actual rpm is greater than the selected rpm. In turboprop engines, rpm is a sole function of blade angle; and in flight at a constant power setting, blade angle is a sole function of true airspeed. A constant‐speed propeller makes changes to the blade angle based on airspeed, altitude, temperature, power lever and speed lever position to maintain a selected rpm. ...
Page 38
RAZAIR‐A1‐METRO‐III‐AFM‐001 The propeller start locks consist of two spring‐loaded pins that engage the propeller piston and, consequently, lock the blades in a flat pitch position. The start locks remain engaged following engine start because of the shear loads applied to the pins by the propeller piston. The start locks are released when ready to taxi by selecting REVERSE with the power lever to remove shear loads. During a normal shutdown, the STOP button is first pushed to shut off fuel; then the power lever is moved into REVERSE as the rpm decays below 50%. As the propeller decelerates the start locks re‐engage. After the rpm decays below 10% the power levers can be released. NEGATIVE TORQUE SENSING (NTS) SYSTEM Negative torque occurs when the propeller drives the engine, as opposed to the positive torque developed when the engine is driving the propeller. Loss of engine power during flight results in loss of positive torque, and the windmilling propeller produces negative torque, which results in drag that decreases performance and increases yaw. The engine has a negative torque‐sensing (NTS) system that provides for automatic drag reduction without any action on the pilot’s part. It is NOT an autofeather system, but rather a system that increases blade angle to reduce windmilling drag. The pilot must still feather the propeller. SYNCHROPHASING After takeoff and when climb power is established, a propeller synchrophaser can be used to synchronize the propeller rpm and establish a blade phase relationship, called synchrophasing. Combining synchronizing and synchrophasing help reduce propeller noise and result in greater passenger comfort. The system operates to match the rpm of the slow engine to that of the fast engine over a very limited range. It is recommended that the engines be manually synchronized before turning the system on. ...

POWER (THROTTLE) LEVER Two power levers operate in a quadrant on the center pedestal which is marked “FLT IDLE”, “GROUND IDLE,” and “REVERSE.” The power lever connects to the propeller pitch control and the fuel control unit. When the power lever is between FLT IDLE and REVERSE, any movement positions the propeller pitch control to provide a blade angle proportional to the power required. When the power levers is positioned forward of the FLT IDLE, propeller pitch control is provided by the speed levers. The power lever can move freely between HIGH (full forward) ...

Their position changes with the speed levers position. The condition levers are actuated automatically as long as the SRL computer is active; otherwise they are locked at their lowest value. WARNING Engine torque tends to increase when the speed levers are at low rpm. An overtorque condition will appear if the power levers are at HIGH while the speed levers are at LOW. Reduce power to keep the torque within safe limits. IF THE OVERTORQUE CONDITION REMAINS FOR TOO LONG THE ENGINE WILL CATCH FIRE . STOP AND FEATHER CONTROL ...
