Recite ERJ Aircraft Limitations Flashcards
When powering-up the aircraft, what minimum voltage is required? When would you need to perform the SOPM charging procedure?
22.5 Volts, if voltage is between 21V-22V.
After the EICAS is powered, how long must we wait before APU start?
- After verifying there is no fire protection fail messages.
- 30 seconds after EICAS is energized.
Can takeoff/landing occur with the “FUEL IMBALANCE” EICAS message?
Yes, as long as it’s less than 794 lbs.
What’s the minimum fuel tank temperature?
-37C
What is the starter cranking limit for start attempts 1 and 2?
90 seconds.
Minimum time between starts 1 and 2?
10 seconds.
How do the starter cranking limits change in flight?
For in-flight starts, the maximum cumulative starter run time per start attempt is 120 seconds (motoring plus start time).
During an engine start, we must see N1 rotation by what N2?
Positive N1 by 50% N2.
A taxiway is NOTAM’d closed to aircraft with wingspan over 100’. What is the wingspan of the ERJ-175?
Wingspan of 93’11”.
For takeoff, what is the maximum brake temperature?
Must be green.
What is the maximum tailwind component allowed for takeoff?
15 knots.
Are static takeoffs recommended with a crosswind component greater than 25 knots? Why?
No, due to engine compressor stall possibility.
After takeoff, when can the autopilot be engaged?
400’ AFE.
What is the minimum runway width allowable?
100’.
ATC reports moderate and possibly greater turbulence ahead. What’s the turbulent air penetration speed? Is it a target or a maximum speed?
270 knots/0.76M, whichever is lower. This is a target speed.
An IDG fails in flight, and the QRH instructs you to start the APU. What is maximum start altitude?
30,000’.
