Chapter 1 Flashcards
What type of aircraft is the T-6A
a single-engine, two-place (tandem
seat), pressurized, low-wing training aircraft manufactured
by Hawker Beechcraft Corporation, Wichita, KS.
What kind of flights are the T-6Aapproved for?
day or night VFR and IFR flight.
Which engine powers the T-6A and what propeller drives the T-?
Pratt & Whitney PT6A-68 free-turbine
turboprop engine with a Hartzell four-blade propeller.
What type of landing gear is the T-6A equipped with
The landing
gear is a retractable tricycle-type which is electrically controlled
and hydraulically operated.
Basic empty weight?
approximately 4900 pounds
Maximum takeoff gross weight?
6500 pounds.
Oil system capacity?
18.5 US quarts
What does the oil system do?
provides a constant supply of filtered
oil to the engine bearings, reduction gears, accessory
drives, and propeller throughout normal and aerobatic flight
maneuvers.
CAUTION: When must the oil system be serviced?
within 30 minutes
of engine shutdown. For most accurate
results, check oil level 15 to 20 minutes after
shutdown.
How do you check oil level?
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.
How is oil pressure and temperature measured?
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.
When will the red oil pressure annunciator be illuminated?
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.
When will the amber oil pressure annunciator be illuminated?
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.
When will BOTH the amber- and red oil pressure be illuminated?
If oil pressure remains between 40-15 PSI at idle power for more than 5 sec
Which units will automatically control the propeller blade angle (pitch) and propeller speed (Np)?
The engine power management unit (PMU) and the propeller interface unit (PIU)
