Gulfstream V Notes

 courtesy of Jeff Beck

Break Transfers

• Auto pilot trips
• Amber Msg: AC Pwr Fail
• Blue Msg: Gen Fail
• In this case the blue message drives the amber

Using Speedbrakes

• Watch the red airspeed trend, it's immediate
• Don't use in high a recovery
• Use only for overspeed (If hand flying, watch for big pitch )
• Pitch OK at lower speeds.

Perf Init check for

• Speed @ 20 flaps = 160
• Speed @ 39 flaps = Vref + 5
• App Climb +0 default auto
• App Climb + SM
• App Climb + Big

Fuel Required

• Manual Fuel Entry or
• Enter zero fuel
• OK on short trips but watch distances > 2000nm as the maximum fuel output will be 14 or 18 K.

Reverser; no limits any more

Engines; Make certain all ground runs are into wind +/- 10 degrees max.

NWS; Gain values

• < 20 kts = constant gain
• > 20 kts = decreasing gain
• Greater than 60 kts, NOT ON NWS !!!

Partial Flap Approaches

• Watch idle speed
• Long spool up times

Ground Spoilers; At lineup have both power levers up before arming.

Flaps Maint Rq; too long moving flap handle

• Technique, Push or pull handle in desired direction
• THEN, pull trigger

Reversers

• Use stowed OR deployed (positive detent)
• If not a T/R Miscompare message will result.

Reversers; Emerg Stow

• Stay stowed until piggybacks are stowed

Entrance Door

• Close before start
• Don't want PTU Pressure during start

Pressurization

• Don’t do a G3 procedure after landing (Man, O/F valve Open)
• Safety valve opens after landing on G5

Hydraulics

• Left Qty 4.8
• Right Qty 1.6
• Don't overfill
• Check Qty on
  • Ground Svc
  • Summary
  • Hyd Page tic mark
• Only valid #’s on CAS with engines running
• CAS indication with eng running IS Temp Compensated, under pressure
• If over filled, maint can burp system, but make adjustment based on CAS Qty indication

Engines; Rotor Bow

• > 20 minutes but listen for rumble even on quicker turns
• If it was parked into headwind and turning, it's better
• QRH says start cycle for 250 degrees
• Shutdown for 2 hours? Do crank cycle then you’ll be ready when pax show.

Pressurization, taxi out

• Tolucca after TO
• Don't use Auto, Use "Semi"
• Once level, if not climbing again, then select Auto
• If stepped descent, > 1000', cabin will descend to Dest –400'.

HF tuning

• Add zero to frequency and Enter

RFMU

• Cross tune valid only if #2 unit is turned off.
• Using H.S.I. page?
  • Before you change course,
  • BE CERTAIN to line select Course
  • Otherwise, you’ll lose the active VHF frequency!!!

APU In flight

• Requires one unit retrim

Heated Fuel Return

• Stagger (side to side) is normal depending upon solar load, fueling, ect.
• Oil temp will decrease 10-15 degrees
• Oil press will increase 10-15 psi
• If it indicates zero degrees and NO Heat?
  • Could be that temp is 0.5 degrees

FQMS message before TO

• Reset Cpit fuel panel
• Prevention, Open fuel door before setting rqd fuel qty

 

EGPWS

• Peaks mode Highest Dis/Lowest Dis
• Uses geometric altitude (GPS)
• Watch out using lower transition levels
• New system is QFE friendly

GPS Approaches RNP.03

• Don’t fly raw data!!!
• MUST use command bars OR Auto Pilot
• Blue data on CDI is not precise enough

Cockpit Temp Cold with Hot Duct?

• Try wing AI
• Try T handles (side console) to about 50%
  • Inlet PAC valves lack muscle even though commanded
• Blue number is requested temp
• White number is actual zone temp

Cockpit Temp Hot with Quick Descent

• Slow as snail stuff to react
• FIX
  • Temp Manual, Full Cold for 5 seconds
  • Back to Auto and set desired temp

FMS Fuel

• Nav – Fuel
• Inverse video if loses FF equal
• Manufactor

Fuel Density

• Not getting full fuel?
• Fuel probe has limited density compensation
• Computer compensation is better than G4 so qty indication is more accurate
• Fuel temp is critical, need fuel?
  • Make sure wing is a empty as possible
  • Use coldest fuel source available (underground?)

Demo Shaker

• F/W Power (-6 more knots)
• Slam accel faster at FL510 (5-10 seconds)
• Slam accel slower at FL450 (30 seconds)
• Because Low idle is > with altitude
• AOA went away? 
  • What does .75 mean
  • Airspeed trend hack tells a lot more.
• At altitude, shaker at –15 kts
• Minus six more knots to stall.

Touch & Go

• Never flaps 20
• Low idle
• No RTD

No Flap Approach

• Speed 133
• Try that with a GEX
• Plan flat approach
• Don't use A/T retard mode, due to radar altimeter readings that might cause power loss

G5 Range Trade-off

• M82-83 costs 4% range versus M80
• M85 costs 11% range versus M80

G4 Range Trade-off

• M85 costs 26% range versus M80
