721 SOP CHPT 3 Flashcards
What is often the restriction time for using APU after ‘On Block’?
5 minutes
APU usage is often limited to a short window around the ‘On Block’ status.
What is often the restriction time for using APU before Target Off-Block Time (TOBT)?
5 minutes
This rule helps manage aircraft operations efficiently.
At what temperature does Bombardier advise caution with the windshield heat system?
Above 30°C.
When should the WSHLD/WIND HEAT be selected to LOW/HIGH in high temperatures?
Until completing the After Take-Off Check.
What is the procedure for High Crosswind Take-Off when the crosswind is more than 10 knots?
Execute static take-off, set thrust to take-off thrust minus 5% N1, check APR ARM message on, and then advance thrust to achieve take-off N1 prior 60 KIAS.
What is the minimum spacing required for Intersection take-off?
3 minutes
This spacing is necessary to ensure safe separation between departing aircraft.
What is the minimum runway length required for a rolling take-off?
TOFL + 200´
What is the procedure for a rolling take-off?
Advance power slowly, through approximately 40% N1, to confirm normal spool up and then set to the take-off N1 setting. Oil pressure minimum of 45 PSI must be checked.
Under which conditions should you consider a static take-off?
When available runway length is close to TOFL and Any time runway conditions or weather conditions demand improved performance.
What is the procedure for a static take-off?
The power will be advanced slowly to approximately 40% N1, while the brakes are applied, to confirm normal spool up. Then advance the thrust levers to the take-off N1 setting and release the brakes
smoothly when take-off N1 is set, or when/if the aircraft begins to skid.
During take-off when do you retract flaps?
Above 400’ AGL, no earlier than VFTO minus 5 KTS with a accelerating trend vector
AGL stands for Above Ground Level.
What should be selected when flying at climb thrust and anti-ice is required?
Wings prior to cowls
This selection protects the cowl overpressure relieve valve.
How often must the PM complete a fuel check?
A fuel check must be performed at least every 60 minutes.
What fuel imbalance should be corrected during enroute / taxi, take-off and before landing?
400/200 lbs.
What is the minimum fuel upon landing?
Minimum fuel upon landing at alternate in Europe is 500 lbs, In remote areas it will be 1,000 lbs.
What is the SOP alternate fuel requirement?
SOP alternate fuel is 1,680/2180 lbs. (includes 880 lbs. for holding 30 min. at 5,000’ and 300 lbs. for an approach and the minimum landing fuel)
In order to not cause TA´s or RA´s in other aircrafts what should you do while climbing?
Reducë the rate of the climb to 1,000 ft/min during the last 1,000’
What is the procedure during a EGPWS / windshear Warning Alert under IMC?
Call Escape x3, press TOGA and increase pitch until just prior to the stick shaker, retract spoilers and maintain configuration.
If flying into airfields not stored in the EGPWS, when should you engage the “EGPWS Mode Inhibit” switch?
When within 25NM of destination airfield.
During Low Level when should you use the GPWS MODE INHIBIT and TERRAIN INHIBIT switch?
The GPWS MODE INHIBIT can be selected below 1.500’ RA. The inhibit mode is disengaged by cycling the Flap Override switch, or when climbing above 1.500’ RA again.
The TERRAIN INHIBIT can be selected at any altitudes and deselected when passing 1.700’ climbing.
Windshear escape should also be executed whenever aircraft control becomes marginal below 1,000’ AGL. Marginal aircraft control may be indicated by indications/changes in flight path in excess of?
15 KIAS, 500’/min vertical speed, 5˚ pitch attitude and Rapid one dot displacement from glide slope!
What is the recommended holding speed?
200 KIAS and 1 minute up to 14,000ft and 225 KIAS and 1,5 minute above.
When should you start the in range check?
Passing FL100, inside 30 NM from the airport, or 10 min from landing.
What is the minimum maneuvering speed for different flaps settings?
45: 145 kts, 30: 150 kts, 20: 160 kts, 0: 170 kts.
The minimum maneuvering speeds are approximately 30% above the stall speed and are valid with the landing gear extended or retracted and for a gross weight of 38,000 lbs. and below at 2,000´ pressure altitude and below.
