Systems 3 Flashcards
Environmental Control Panel basic info.
Co-pilots instrument panel, left side is bleed air controls, Must have at least 1 engine running for bleed air. Kept on Auto FLDK and usually Cold-Hot dial around the 10 o’clock position. Right side is all electric, must have generator or ground power
What does electric heat require?
Ground power unit.
AUX COOL can be used with what?
Ground power or aircraft power, must have 2 generators operating to use with aircraft power
Avionics Blower
Constantly runs
BLO 1
Controls the aft blower/evaporator
BLO 2
Controls the forward blower/evaporator
AUX COOL
Turns on the VCCS (Vapor cycle cooling system)
Cabin Altimeter
Should never exceed 10,000 feet and Cabin Rate of Climb (max PSID is 9.1)
What happens if EMER Bleed Air is selected?
AIR COND FAIL annunciator illuminates as well as master caution
The air coming out of the ACM
Is 39°
How are the nose and tail anti-ice systems heated?
Electrically
How are the wing and engine nacelles anti-ice systems heated?
Bleed air and ram air
How do you activate the oxygen system in a CSO modded T-1?
Pull both oxygen knobs located on the copilot’s side
If unmodded (slick/ Randolph AFB) T-1s how do you activate the oxygen system?
Pull only the right (silver) knob. The left (red) knob will deploy the overhead passenger oxygen masks
What happens if the blow-out green disc is not there?
Must get the oxygen system serviced by maintenance.
Cabin Pressure Lo
Cabin Altitude 9500 +/- 500
Cabin Pressure High
On the inner scale, 11 +/- 1 PSID
WING OV HT
Greater than 212° in the piccolo tube or 350° before the mixing point-TURN OFF WING ANTI-ICE!
Stab Anti-Ice Fail
Turn off anti and the stab de-ice and use the de-ice backup switch
L ENG ICE TEMP LO
Temp in the leading edge of the engine nacelle is less that 120 degrees
Wing Ice Temp LO
Wing below 140°
Icing
.02 inches of ice on the ice detector
Ice Det Fail
Detector doesn’t work
PASS OXY ON
Pulling the red knob
AIR COND FAIL
Greater than 53 PSI going into the compressor or greater than 400° degrees coming out of the compressor
STAB DE-ICE FAIL
Kill the de-ice and anti-ice and use backup de-ice switch
DEFOG AIR OV HT
Greater than 200° degrees in the defog ducts
DOOR UNLOCK
Main cabin or AFT fuselage door is open
BL AIR DUCT FAIL
3.5 +/- .5 PSI or greater than 350° in the ducting near ACU
PITOT HT OFF
Both systems have failed or has been turned off
CABIN AIR OV HT
390° +/- 15 degrees in the cabin ducting
Bleed air is used for
Cabin pressurization, heating and cooling, wing and engine anti-ice, hydraulic reservior pressure, door seal
AV BLO FAIL Annuciator
Push the AV standby blow switchlight
How do we control the cabin pressure?
Regulate the outflow valve of the cabin pressure controller
Cabin altitude
9500 +/- 500 feet
On the bleed air panel, what position on the bleed air knob gives you unconditioned air (600° air coming through the “bathtub fitting” in the aft cabin near the toilet)
