Study Notes

Auto Start and Ignition

PMU energizes/de-energizes igniters with ignition switch set to NORM.
EYD PX LO caution remains lit until system pressurizes if the emergency accumulator is discharged; ensure light is off prior to flight.

OBOGS and Fuel Systems

OBOGS FAIL annunciator is inhibited for 3 minutes after initial power-up during warm-up.
Low fuel warning lights provide minimum fuel level indication even if a fuel probe fails.
Auto fuel balance system keeps wing tank fuel levels within 20 pounds of each other.

Canopy and Operating Limits

Canopy must not be opened on the ground with surface winds exceeding 40 knots.
Maximum airspeed in turbulence is 207 KIAS.

Engine and Oil Systems

SCU activates red OIL PX light if oil pressure falls below 40 psi at higher power, and below 15 psi at idle.
Total oil system capacity is 18.5 quarts; oil level should be checked 15 to 20 minutes after shutdown for accuracy.

Emergency Procedures and Landing

A thrust and weight-on-wheels switch fault triggers PMU STATUS light in flight.
During emergency conditions, "land as soon as possible" requires immediate landing at the nearest suitable site; "land as soon as practical" indicates less urgent emergency without immediate landing necessity.

Spin Recovery

Neutral spin recoveries demonstrated to cease spin within 2 additional turns after control neutralization.
Incipient spin phase lasts approximately 2 turns.

Weight and Dimension Specifications

Aircraft empty weight is 5040 pounds, while maximum takeoff gross weight is 6900 pounds.

Aircraft Systems and Performance

Best glide speed while landing gear down and flaps retracted is 105 KIAS with a 1500 feet per minute sink rate.
Engine is flat-rated to produce 1100 shaft horsepower; propeller system maintains 2000 RPM under most flight conditions.

Operational Guidelines

Do not touch the parking brake handle shaft during actuation/release to avoid injury.
Controls in the rear cockpit take priority in trim conflicts.

Miscellaneous

During inverted flight, the inverted fuel pickup provides 60 seconds of fuel supply.
The chip detector is located in the reduction gear box to monitor oil contamination.
Above 60% torque, full right rudder and aileron may not stop left roll-off during stall.

Maintenance Alerts

If the hydraulic pressure in the emergency accumulator drops below 2400 psi, EHYD PX LO light activates.
Any fault during overspeed governor check necessitates a ground abort.

Comparison of Flight Modes

IDLE torque ranges from 1 to 10% on the ground; in flight mode, idle torque is typically around 67%.

Safety and Inspection

Top latch mechanism of the ejection seat should be checked during preflight; gear extension/retraction sequence takes approximately 6 seconds.
Be cautious of brake wear indicators; reset the parking brake if an indicator reads low and re-check.

Emergency Equipment and Battery

Auxiliary power supplied by a 24 volt, 5 amp auxiliary battery in the left avionics compartment; external power during engine starts minimizes ITT and extends battery life.
