175 CQ 2023 Flashcards
What does TCS stand for? Does this button have authority over the auto pilot and flt director?
- Touch Control Steering Button, sometimes referred to as the AP?FD TCS button.
- Yes
Describe the Flt Directors interface with the TCS button?
Pressing and holding the TCS button Synchronizes the Flt Director with the current airplane attitude.
If the airplanes pitch is 30 degrees nose down and bank is 50 degrees right, will pressing th TCS button align the FD with that attitude?
Yes, the FD will follow the airplane/pilot inputs when the TCS is pressed.
When the TCS button is pressed the Flight Director follows the airplane. can you identify a potential threat if the above statement is not understood?
The flt director is not guiding the pilot when the TCS button is pressed. If attitude and or piston are not carefully monitored the pilot could follow the flt director into and undesired aircraft state.
When the TCS button is released, what happens to the Flt Director guidance?
- The Flt Director returns to the lateral and vertical selection when the TCS was pressed.
- with Roll/VS/FPA modes the FD maintains the airplane attitude when the TCS is released
How does the Autopilot interface with the TCS button?
Pressing and holding the TCS will override the AP. Releasing th TCS button will allow the AP to resume control.
The AP is engaged with LNAV and VNAV active and the pilot presses the TCS button. The ERJ is then manually flown away from the lateral and/or vertical course then th TCS button is released - What will happen?
The AP will resume control and attempt to bring the ERJ back to course both laterally and vertically.
If the ERJ had been maneuvered significantly off of the CRS and/or PTH with the AP engaged, and then the TCS button released, could this create an unsafe condition in the cabin? HOW?
The AP has significant authority to bring the ERJ back ro CRS/PTH and could be unsafe for pass and cabin crew if they are not seated with seat belts fastened.
Have individuals been injured in the ERJ cabin from improper use of the TCS button?
Yes
If a momentary “correction” of the ERJS flt path is desired, is th TCS button a valid option?
Absolutely, as long as the pilot understands its operation
How can a pilot minimize the possibility of hazardous positive or negative G loading of unsecured pass and inflight crew when using/ releasing the TCS button {AP on) ?
- Return the ERJ to the CRS and/or PTH before releasing the TCS button
- Or select new vertical and/or lateral modes that better align with the new/desired flt path.
- or turn AP off.
The fwd cargo door position indication is deferred. What does the bold (T) symbol communicate?
- Tracking or time restriction
- Repair interval Cat A one day
- Procedures that must be performed, tested prior to flit or at specified interval.
What does the bold (L) log book entry mean?
- The MEL requires a repetitive mx action (T) by the flt crew and must be accompanied by an associated log book (EAML) entry each time.
- Call to MX control is required.
For a fwd cargo door sensor failure ME>, what EICAS msg might be displayed? could there be associated Aural and or Master WARN?
- DOOR CRG FWD OPEN
- Yes there would be associated Aural and Mster Warnings.
With this Warning (DOOR CRG FWD OPEN) be inhibited on T/O?
Yes, K3 INHIBITION code (T/O)
With this MEL applied properly for a FWD Cargo Door indication, if a DOOR CRG FWD OPEN populates after Takeoff, what would be the appropriate action?
Mitigation strategies should have been employed as part of the MEL review and operation procedures contained therein. No crew action bryon confirmation of the EICAS msg and alarm cancelation is required - this is a nuisance msg. from a faulty sensor.
Does this MEL DOOR CRG FWED OPEN effect pressurization?
No, this is just an indication issue, the door has been confirmed closed and fully operational as part of the procedure.
Describe what normal system pressurization looks like?
EICAS indication lowers right had corner Check ALT, RATE and DIFF Press.
1. ALT cabin altitude is lower than airplanes altitude and remains below 8000
2. RATE cabin alt ins increasing at a rate less than or equal to normal system “Internal range” of +750
3. DIFF PRESS approaching 7.8 to 8.4, increasing with time and/or alt.
If you received DOOR CRG FWD OPEN how would you know if you were depressurizing?
- ALT is approaching or matches airplane set.
- Rate cabin alt is increasing at a rate grater than normal + 750
- DIFF Press approaching 0
If the QRH requires you to push the DUMP BUTTON, what does this do?
Provides rapid cabin depressurization, by opening the outflow valve and commanding the packs and recirculation fans to off.
If a DOOR CRG FOWD OPEN EICAS Warning msg. populated after T/O and the door sensor is not deferred, does this indicate the airplane will not pressurize?
If the door is actually open, the airplane will not pressurize, the QRH will help the pilot determine its status.
