Scenario 6 Flashcards
Alternately, the weather is at the other end of the spectrum. It is now lightly snowing and the OAT is 1 degree C. The airport is backed up with takeoff delays running 45 minutes.
Q.6.1. When can you use engine and/or APU bleeds after deicing?
Wait one minute prior to turning engine and APU bleeds on after deicing.
Alternately, the weather is at the other end of the spectrum. It is now lightly snowing and the OAT is 1 degree C. The airport is backed up with takeoff delays running 45 minutes.
Q.6.2. Besides our normal de-ice and anti-ice procedures, ENG ANTI-ICE switch – ON, are there any other considerations regarding the engines?
Yes, engine run-up procedures.
Alternately, the weather is at the other end of the spectrum. It is now lightly snowing and the OAT is 1 degree C. The airport is backed up with takeoff delays running 45 minutes.
Q.6.3. How do we perform the run-up in an NG?
Run-up to a minimum of 70% N1 for approximately 30-second duration at intervals no greater than 30 minutes.
Alternately, the weather is at the other end of the spectrum. It is now lightly snowing and the OAT is 1 degree C. The airport is backed up with takeoff delays running 45 minutes.
Q.6.4. Would the procedure change if you have extended ground operations in moderate icing conditions?
Yes.
Alternately, the weather is at the other end of the spectrum. It is now lightly snowing and the OAT is 1 degree C. The airport is backed up with takeoff delays running 45 minutes.
Q.6.5. What is different in extended ground operations in moderate icing?
Run-ups to a minimum of 70% N1 for approximately a one-second duration at intervals no greater than 10 minutes.
Alternately, the weather is at the other end of the spectrum. It is now lightly snowing and the OAT is 1 degree C. The airport is backed up with takeoff delays running 45 minutes.
Q.6.6. How do run-up procedures differ for MAX?
The N1 and run-up times are different.
Alternately, the weather is at the other end of the spectrum. It is now lightly snowing and the OAT is 1 degree C. The airport is backed up with takeoff delays running 45 minutes.
Q.6.7. On the NG aircraft, what is the function of the engine anti-ice system?
Prevent ice formation on the engine cowl lip.
Alternately, the weather is at the other end of the spectrum. It is now lightly snowing and the OAT is 1 degree C. The airport is backed up with takeoff delays running 45 minutes.
Q.6.8. An amber COWL ANTI-ICE caution light indicates what condition on the NG?
Excessive pressure in duct from cowl anti-ice valve to cowl lip.
Alternately, the weather is at the other end of the spectrum. It is now lightly snowing and the OAT is 1 degree C. The airport is backed up with takeoff delays running 45 minutes.
Q.6.9. On the MAX aircraft, what is the function of the engine anti-ice system?
Prevent ice formation on the engine cowl lip and engine core.
Alternately, the weather is at the other end of the spectrum. It is now lightly snowing and the OAT is 1 degree C. The airport is backed up with takeoff delays running 45 minutes.
Q.6.10. The amber COWL ANTI-ICE caution light has identical meaning between the NG and MAX; however, the MAX has 2 additional caution lights on the Engine Anti-Ice Panel, what are they?
ENG ANTI-ICE and COWL VALVE.
Alternately, the weather is at the other end of the spectrum. It is now lightly snowing and the OAT is 1 degree C. The airport is backed up with takeoff delays running 45 minutes.
Q.6.11. What do ENG ANTI-ICE and COWL VALVE lights mean?
ENG ANTI ICE indicates cowl thermal anti-ice has been inhibited due to a system failure or when an engine core anti-ice valve fails closed. COWL VALVE illuminated steady indicates cowl anti-ice valve disagrees with related ENGINE ANTI-ICE switch position.
Alternately, the weather is at the other end of the spectrum. It is now lightly snowing and the OAT is 1 degree C. The airport is backed up with takeoff delays running 45 minutes.
Q.6.12. How can a Crew determine if an intersection takeoff can be used?
An intersection takeoff may only be performed if the Flight Deck Crew determines that performance data is available and used for that intersection takeoff.
