I'm not a pilot but found this interesting. A lot of systems to precheck before even starting on the preflight. Wow!! Thanks for the insight. Looking forward to seeing more.
I just Study initial maintenance training for ERJ 190, for myself, and tis video is excellent explanation about of starting with APU and GPU. Ver y good. Thank you so much
Yeah he forgot to turn EMER light after GPU connected. But on Boeing planes pilot do the fire warn procedure later during IRS aligning. Not sure if he should have done that during FLT CTL test
As the content creator said, the transfer is automatic. The only thing you have to do is push the GPU button out. It will still read “AVAIL” on the button.
Questions: 1. Does the APU Gen get pressed (white light off) before or after the APU start? 2. Does the DC Pump have to be on? and then after engine start does it come off? Thanks.
The APU GEN pushbutton is normally kept pushed in before start thus the striped bar is off. The DC fuel pump control knob should be kept in AUTO . After APU starting the system automatically shuts off it once APU is feeding the main AC buses and then RH AC fuel pump Will feed the APU. To do that, the RH AC fuel pump control knob should be in AUTO also.
APU needs to be started up before adding any other electrical devices, otherwise u will drain the batteries below 21 volts. Nav lights, beacon, inspection and airline insignia go on last...
@@L1011DFW the battery will *eventually* drain with electrical power on and without GPU, APU, or eng power. However, the position (nav) lights should be turned on whenever an aircraft is powered up, especially if hydraulics are on and flight controls are moving. It can be extremely hazardous to those on the ground outside the aircraft to not know when an aircraft is powered up. With light aircraft, the beacon light (or strobes if no beacon present) is used to warn people in the same manner. In all my years of flying, I've never once turned off a beacon light because I've always made sure to keep it on as a signal to others the the aircraft is powered up (and engine start may commence at any moment).
should you really be using the ptu this way? 175/190 checks before departure are at least 25 minutes, the hydraulics will get to temp on their own by then.
what pumps should be on when defueling, or cockpit fuel pumps switch configuration for defueling both tanks simultaneously to avoid fuel imbalance after defuel. Thanks
Depends, If you are defueling both tanks like you mention, no much you can do. The defuel truck will open the valves needed. You will run into fuel imbalance if the pressure fueling system is broken. if thats the case over the wing defuel takes place. But id you just transfering from tank to tank, just turn the opposite engine pump to help out with the transfer.
I have a problem with this airplane. When preparing for takeoff, a wing walker must make a 90 degree walk to the GPU and communication panel to disconnect the LAN connection, WHILE ENGINE ONE IS RUNNING. The distance between engine one and this panel seems very short. Because from my understanding, the dangerous ingestion zone is 15 Feet. Does anyone know the distance between the GPU/communication panel and engine 1?
I work as a ramp agent, normally the Captain starts Engine #2 so the wing Walker is not near the side with the running engine. I'm not sure if the distance of the Ingestion zone to the GPU Panel
@@erikdegby4652 Woah! Are you sure? It makes more sense this way! I am a ramp agent, that works with this aircraft. Engine 1 is started after pushback and then we walk in a 90 degree line towards the GPU panel to disconnect everything😳. They tell us walking the 90 degree angle keeps us safe and away from ingestion zone while that thing is running😡!
yes. but GPU will be disable due to power transfer from GPU to APU (APU has priority as main source of electrical power). but, if APU is broken GPU is use with ground air power
Im surprised the aircraft doesn't have something like a CMOS battery to keep track of the time. Unless 'm not understanding what I see on the clock screen w hich seems ot be showing the time since you connected GPU power :)
it shows Zulu time, local time, date and chrono. As for the battery there is an alarm that alert the crew that the batteries are draining (ground crew horn will sound)
can you charge the E170's BATT with the APU or do they need to be removed like a S-105 to get a full charge.... I kept getting a Low Volt light starting... mechanic told be it was nothing to worry about... removing the Battery and charging it seemed to solve the problem. I do not use it enough to keep the battery charged..... even though all the systems are off I still drain the battery to the point where I have to do a Manual start (which i might add is Incredibly Dangerous and No one should ever do this with even the smallest beach-craft)
Yo can recharge the batteries with APU. It will ussually take about 45 minutes to charge (depending on how low they are) The batteries get to a point to where it cannot not be recharge, anything less than 10v. So, replacing the batteries is your best option.
AV rated Battery's are How much??? and where in Alberta Do I get a new one? Reconditioned are good but they will only warranty them for a year. I have been renting but he gives me discounts if I do Maintenance. I spend too much time on the ground because of my Vertigo....
Autobrake isn’t really necessary. Having flown the 145 and now starting into this, you can simply step on the brakes and get as much effective stopping. For autobrake to work, you need weight on wheels and a speed over 60 knots for 3 seconds. The second you touch the toe brakes, they disengage anyway. I’d say they’re helpful on RTO mode, but landing numbers don’t have autobrakes factored, except you do get the runway distances through ACARS.
SEE THE SWITCHES, ON THE CENTER COLUMN-THAT IS WEATHER SERVICES, VOR, LORAN, ETC. YOUR THINKING PRE-1998 AIRBUS@ USC 49 CHP. 7 STATUTE 207 OR TURN ON THE ENGINES WITH THROTTLE 0%, OTHERWISE BEFORE MOVE THE STICK THROUGH ALL POSITIONS-REMEMBER 2018.
In the first 12 seconds, I can tel this will be awful. "Ground Power and GPU power"! Guess what, they are one in the same. Didn't watch past 12 seconds. I have an EMB-145 type and 8000 hrs in this airplane.
