Chapter 1

Question 1

What type of aircraft is the T-6A

Answer 1

a single-engine, two-place (tandem seat), pressurized, low-wing training aircraft manufactured
by Hawker Beechcraft Corporation, Wichita, KS.

Question 2

What kind of flights are the T-6Aapproved for?

Answer 2

day or night VFR and IFR flight.

Question 3

Which engine powers the T-6A and what propeller drives the T-?

Answer 3

Pratt & Whitney PT6A-68 free-turbine turboprop engine with a Hartzell four-blade propeller.

Question 4

What type of landing gear is the T-6A equipped with

Answer 4

The landing gear is a retractable tricycle-type which is electrically controlled and hydraulically operated.

Question 5

Basic empty weight?

Answer 5

approximately 4900 pounds

Question 6

Maximum takeoff gross weight?

Answer 6

6500 pounds.

Question 7

Oil system capacity?

Answer 7

18.5 US quarts

Question 8

What does the oil system do?

Answer 8

provides a constant supply of filtered oil to the engine bearings, reduction gears, accessory drives, and propeller throughout normal and aerobatic flight maneuvers.

Question 9

CAUTION: When must the oil system be serviced?

Answer 9

within 30 minutes of engine shutdown. For most accurate

results, check oil level 15 to 20 minutes after shutdown.

Question 10

How do you check oil level?

Answer 10

The sight glass is not to be used for checking oil level; only the dipstick is to be used for correct indication of oil level in the tank.

Question 11

How is oil pressure and temperature measured?

Answer 11

Sensed by transducers downstream of the main oil pump and the signal is sent to the engine data manager (EDM). The EDM passes the oil pressure data to a signal conditioning unit (SCU) computer that contains the logic to illuminate the warning annunciators on the central warning system (CWS) panel under the following conditions.

Question 12

When will the red oil pressure annunciator be illuminated?

Answer 12

When oil pressure drops to 40 psi or below with PCL above idle, or when oil pressure drops to 15 psi or below at PCL in idle.

Question 13

When will the amber oil pressure annunciator be illuminated?

Answer 13

When oil pressure drops to 40-15 psi with PCL at idle, or when oil pressure drops to 90-40 psi for more than 10 sec with PCL above idle.

Question 14

When will BOTH the amber- and red oil pressure be illuminated?

Answer 14

If oil pressure remains between 40-15 PSI at idle power for more than 5 sec

Question 15

Which units will automatically control the propeller blade angle (pitch) and propeller speed (Np)?

Answer 15

The engine power management unit (PMU) and the propeller interface unit (PIU)

Question 16

To which pressure altitude do you have 100% torque on a standard day?

Answer 16

12,000 to 16,000 feet MSL

Question 17

How many HP is the engine producing at 100% torque?

Answer 17

approximately 2900 foot-pounds of torque at the prop shaft. This equates to approximately 2750 pounds of thrust at sealevel, zero airspeed.

Question 18

What are the three basic conditions in relation to the propellor pitch?

Answer 18

Feathered, low pitch (flat or fine), and high pitch (coarse).
