RI-12 (I4202):  7/30/05

•	Procedure Track
* Employs teardrop, arc, etc. to achieve alignment by FAF.  Enter shortest direction to intercept track at IAF.  Can use normal leads if within 90 deg.  Can turn inbound whenever you're ready on teardrop unless depicted.  Don’t use published lead points: turn later depending on GS.  Descend when on a parallel or intercept course.  Don’t descend inbound on teardrop until established on inbound course.

•	GPS Characteristics/Approach 
* IEC 9002M FMS, Integrated GPS.  Updated with Jepp NavData Database, kept current. Jane's says 1 m accuracy w/ P(Y), not in this installation.
* Two types of GPS approaches:  Standalone (Made with RNAV T- or Y- IAF setip.) or Overlay (GPS revision of extant approach, indicated by OR GPS in title.)  
* Course sensitivity: Enroute mode (>30 NM from apt.): 5 NM full-scale deflection.  Approach mode (within 30 NM of apt.): 1 NM full-scale.  Final approach mode (2 NM from FAF): 0.3 NM full-scale, Missed approach mode (Past MAP): 1 NM full-scale.
* In order to shoot approach:  Need 1) RAIM (real and predicted), 2) Approach 'Mode Armed (to proceed past FAF), 3)  Entered flight plan in FMS, 4) Up-to-date database, 5) Check GPS, Jepp Notams, 6) Good startup self test, 7) No pending MSG lights.
* GPS approach brief: standard, also compare loaded approach to published approach, published chart takes precedence.  GPS does not track stepdown fixes. 
* RAIM Integ fail prior to FAF: descend to FAF alt, proceed to MAP by way of FAF.  After FAF integ fail: Go missed, or go backup.
* LDRODs check: not entirely applicable.
* Must manually sequence to MAP.  Do not turn prior to MAP.
* Load:

•	Fuel System
* 387.6 gal, 384 useable
61 gal in nacelles.
XFER on at 42-51 gal, 59 backup.
XFER fails, lose 28 gal trapped fuel.  
3/8 full nacelle tank opens gravity feed.
500 pph for XFER pumps.
1. Total fuel system capacity 387.6 G
2. Total usable fuel 384 G
3. Crossfeed allows use of all tanks to either engine.
4. Fuel is transferred from the wing tanks to the center section tank by gravity.
5. Fuel is transferred to the nacelle tank by the transfer pump.
6. Nacelle float switches: 	High level (59G)- turns transfer pump off if 51 Gal switch fails.
			Mid level  (51G)-turns transfer pump off
			Low level (49G)-turns transfer pump on
7. In override, the transfer pump runs continuously, the float switches are bypassed, & the 3psi press switch reset
8. With a failed transfer pump, the fuel gets to the nacelle tank by gravity feed.
9. There are 10 fuel drains on the aircraft.
10. A fuel capacitance gauging system is used in the T-44.
11. The only diff between the left and right fuel system: (1) the left has crossfeed (2) the right has thermal relief valve & line from crossfeed system..
12. A minimum of 42 gallons of fuel is req in the Nacelle tank to obtain a good test of the transfer pump.
13. The boost pump provides 30 psi of pressure to the engine driven fuel pump.
14. It takes 5psi of pressure to activate the FUEL PRESS light.
15. It takes a 30 second pressure delay to activate the NO FUEL TRANSFER light.
16. The engine driven fuel pump supplies 800 psi pressure to the engine.
17. The indications of a boost pump failure: with crossfeed in 'auto': [1] red 'FUEL PRESS' light illums and goes out very quickly [2] yellow 'FUEL CROSSFEED' light illums [3] master caution light flashes [4] gradual loss of power on affected engine beginning at 13,000'.
18. The TBO for an engine driven fuel pump operating on suction lift is 10 hours.
19. The TBO for an eng running on AVGAS is 150 hours.
20. The crossfeed is not left open with the boost pumps operating because fuel may be inadvertently crossfed from either fuel system to both engines because of variances in pump pressure
21. Since the crossfeed valve is electrically opened, if it losses total electric power (i/e battery drained and generators out), it will be closed.
22. The firewall valve is not used to secure an engine because severe damage could occur to the engine-driven high pressure fuel pump (while cavitating) because it obtains essential lubrication from fuel flow.
24. Fuel quantity error can in total can by as high as 100 lbs, while nacelle can only by 50 lbs.  
25. The syphon break is located on the outer wing and opens to prevent negative pressure build up in the fuel system (normally caused by thermal expansion).
26. The purpose of the fuel vents are to provide ram air pressure to prevent tanks from collapsing as they lose fuel to the engine.
27. If either fuel bus fails, the boost pump will still work because it's wired to the hot battery bus.
28. If the transfer pump CB popped, I would get the following indications: red 'NO FUEL TRANSFER' light WON'T ILLUM!
29. The min distance the fuel truck can come to the airplane while refueling it is 50 ft.  For the refueling point ______ft.
30. Fuel flow from outboard tanks to the engine: gravity feeds to the center inboard tank, through transfer pump to the nacelle tank, through the boost pump, by the firewall shutoff valve, through the fuel filter, through the fuel flow transmitter, through the fuel heater, through the engine driven fuel pump, controlled by FCU, controlled by start control unit, to the engine fuel nozzles, into the combustion chamber.
31. Refueling distances: (1) 10' from any port of an aircraft (2) 20' from fuel vehicle or fuel filler point.
FUEL SYSTEM EMERGENCIES (NATOPS 15-4, 15-6 to 15-7)
1. NO FUEL TRANSFER LIGHT
	[1] Check total and nacelle fuel quantity
	If no fuel in wing tanks (if nacelle quantity = total quantity):
	[2] Transfer pump - OFF
	If fuel in wing tanks:
	[3] Transfer pump - OVERRIDE
	If light remains on:
	[4] Transfer pump - OFF (lose 28 Gallons)
	[5] Land as soon as practicable
2. CROSSFEED light illumination: illuminates when boost pump fails or engine fails.  If boost pump failure: [1] close crossfeed switch.  If boost pump failed: [1] Failed boost pump - OFF [2] crossfeed - OPEN [3] Land as soon as practicable.  If not a boost pump failure, reset the crossfeed valve to 'AUTO.'  If engine failure, accomplish EMERGENCY ENGINE SHUTDOWN CHECKLIST.
3. Failure of the engine driven fuel pump - Engine WILL FLAMEOUT.  Accomplish EMERGENCY ENG SHUTDOWN CHECKLIST.
4.  If fuel leak - consider securing electric systems which may contribute to wing fire.  Secure nav lights, strobe lights, fuel vent heaters, and AOA.  Secure inboard wing items with gang bar.  If destination can be reached without dual engines, consider shutting down engine on side of fuel leak.  Secure engine as follows:
[1] Condition Lever - FUEL CUTOFF
[2] Emergency Shutdown Checklist - EXECUTE
5. If fuel syphoning - [1] Airspeed - 140K [2] Land as soon as practicable.  Avoid extreme nose low attitudes. 
6. Single engine crossfeed:
[1] Boost pumps - ON
	[2] Transfer pumps - AUTO
	[3] Crossfeed - OPEN (check crossfeed light on)
	[4] Boost pump (nonfeeding tank, tank w/o FUEL PRESS light ON) - OFF
