TAXI BEFORE TAKEOFF

In the unlikely event that you make the wrong turn during taxi out, what is the minimum taxi strip required to complete a 180° turn?

62 feet

What is the Minimum Turning Circle Diameter required to avoid striking other aircraft or obstruction while executing a 180° turn?

112 feet

What is Wing Growth?

Wing Growth is the fact that some swept wing aircraft's wing making a larger arch outside the width of the wing when you execute a taxi turn while locking the inside brakes.

Does Wing Growth effect the GV?

Yes the GV Wing will arch 2 feet 4 inches outside of it’s normal straight ahead path while making a taxi turn and holding the inside brake. 

Just prior to Line-Up, you select INHIBIT on the eyebrow panel to inhibit tones. What message tones will not be inhibited when the INHIBIT Switch is selected?

All Red MESSAGES and Amber CAT II INVALID, and COUPLED DATA INVALID

Why does the Weather Radar go into Forced Standby on landing?

So you don’t accidentally microwave a ground guide.

How can the Weather Radar be taken out of Forced Standby if you want to take a quick look at the weather prior to takeoff?

Press the TGT Button 4 times in 3 seconds.

Is there any simple way to remember how to navigate through the Quick Reference Handbook tabs?

Yes, everything is listed in alphabetical order in the messages and also in the Tabs. However, you can also quickly find Abnormal / Emergencies by remembering a few simple things about the aircraft:

• Tab 1 The GV is an electrical aircraft; therefore electrical malfunctions are in this tab.
• Tab 2 Two engines, everything associated with engine malfunctions is listed here. 
• Tab 3 Three places where fires can be extinguished along with fire detection problems.
• Tab 4 Four flight control surfaces and associated malfunctions.
• Tab 5 Hydraulic Pumps and associated malfunctions.
• Tab 6 Six landing gear wheels and associated malfunctions.
• Tab 7 Seven Bleed Air Ducting, overheats and associated malfunctions.

Remember, the QRH is set up in Alphabetical Order. Therefore, some things will seem out of place. (i.e. COOLING TURBINE HOT will be in Tab 1, Weight On Wheels Malfunction and Windshield HEAT Malfunction will be in Tab 7.)

IN the QRH Tab 4, Page 5 (03-13-21 JAMMED AILERONS) # 6. What does the following statement mean? "Flight Spoilers Hydraulic Power Requirements......CONSIDER BASED ON AMOUNT OF FLIGHT SPOILER DEPLOYMENT".

Turn OFF the SPOILER CONTROL on the Center Console if the FLIGHT SPOILERS become uncontrollable with the Aileron Jammed Up. Recall, the Flight Spoilers will augment the Roll Control when the Ailerons move more than 1/2°. With the Ailerons › 1/2° the Flight Spoilers will deploy that much further up to a max of 47°.

In the QRH Tab 4, Page 14 (03-13-91 AILERON HOPS ACTIVATION). What does the following statement mean? "IF HARDOVER CONDITION IS DETERMINED TO BE CORRECTABLE OR CORRECTED":

What were you doing prior would be an operable phrase. If you were in Moderate to Severe Turbulence, you might consider pulling and resetting the appropriate circuit breakers. However, if your were in smooth air, you might leave it alone without pulling and resetting the circuit breakers. Recall, the Aileron HOPS has a ½ second delay before activation. Therefore, if you are flying at 206 Knots and are moving the roll control from stop to stop, the HOPS should not activate.

In the QRH Tab 7, page 10-11(03-22-20 SMOKE IN BAGGAGE COMPARTMENT, AFT GALLEY OR LAVATORY, ITEM 8): ,How long should you press and hold the "HOT MIKE" on the Jump Seat Audio Control Panel for it to activate the Audio Panel on the Smoke Evacuation Valve Panel forward of the Baggage Compartment Internal Door?

2 Seconds.

In the QRH Tab 4, page 1 (03-12-00 FAILURE OF FLAP / STABLIZER SYNCHORONIZATION) Which part of the checklist is for Flaps and which part is for the Stabilizer?

• If you have a Flap Malfunction which would be indicated by amber messages:
  • FLAP ASYMMETRY
  • FLAP CMD INVALID
  • FLAPS FAILED
  Then Perform (03-12-00 FAILURE OF FLAP / STABLIZER SYNCHORONIZATION) items 1 through 5, then perform checklist in QRH Tab 4, page 2, (03-12-30 PARTIAL OR JAMMED FLAPS LANDINGS)
• If you have a Stabilizer Malfunction which would be indicated by amber messages:
  • FLAP / STAB IND OP
  • FLAP / STB MISCOMPARE
  • FLP / STB SYNC FAIL
  • STABLIZER FAILED
  Then Perform (03-12-00 FAILURE OF FLAP / STABLIZER SYNCHORONIZATION) items 6 through 11, then perform checklist in QRH Tab 4, page 2, (03-12-30 PARTIAL OR JAMMED FLAPS LANDINGS)

How do we obtain VREF -----APPROPRIATE TO CONFIGURATION as depicted in QRH Tab 4, page 2, (03-12-30 PARTIAL OR JAMMED FLAPS LANDINGS)?

Display Controller, FLT/REF page, in lower right-hand corner of display.

Where does the Display Controller obtain inputs to calculate correct Vref speeds? 

SAT, Pressure Altitude, Aircraft Weight and FLAP HANDLE POSITION.

Can we obtain the Vref speed anywhere else?

Yes, in the back of the QRH in LANDING PERFORMANCE 04-10-20 LANDING SPEED SCHEDULE
