Cool, thanks Bryan.yoni63 wrote:Nav lights on when aircraft is receiving any power, ground or APU, and I think Allen already answered you on the beacon light. Go by your checklists, if you don't have any, check the company site, there are some there for download.
You forgot about lavatory lights...tsk tsk tsk.nwadc10 wrote:Beacon: Turned on during the cleared to start checklist. Usually the cleared to start checklist is in two parts. The first part "to the box" or "to the line", however that airline has the checklist organized, is done prior to pushback. The remainder is completed after the ground crew, or ATC if applicable, gives you clearance to actually start the engine(s). What you probably witnessed was the crew being ready to push before the ground crew was done loading bags. If not, could be a mx issue or crew got to the airplane late due to various reasons.
Nav Lights: Generally on any time electrical power is on the airplane. The intent is to make the wingtips more visible to someone who is about to run into them. It also helps to have them on when preflighting to determine all the nav lights work properly
Strobe Lights: On any time entering an active runway and for the remainder of the flight until the aircraft is clear of the runway after landing. Exceptions are if in the PIC discretion the operation would be safer with them off (flying thru clouds at night can be an example)
Landing Lights: Turned on upon receiving takeoff clearance and turned off during the climb checklist which commences at 3000 ft AFE. They are turned back on upon receiving landing clearance.
Taxi Lights: On during taxi (discretionary during day time) and left on, unless the aircraft comes to a stop, until 10000 ft MSL. Turned back on descending thru 10000 ft. On some occassions the taxi lights are turned on higher than 10000 ft but the reason doesn't apply to cargo operations. The approach check is done at 10000 ft or 10 minutes from touchdown to give the FA time to clean up the cabin. Taxi lights are turned on during the approach check.
Dome Light: On any time you need to read the paper in anything less than daylight.
Map Light: on when you need to read the checklist in less than daylight.
Emergency Lights: Hope you never have to use them, let's just leave it at that.
Head Lights: On during automotive operations in anything less than daylight and in most states required anytime of reduced visibility including rain.
Everything you wanted to know about lights...hope that helps.
The brake lights should come on when you deploy the spoilers. The turn signals will come on when you turn left or right. You just need to hit the little lever on the left side of the yoke. (Of course, when they're not working as per MMEL, you can always roll down the window and use hand signals -khelm wrote:What about Brake lights? Turn signals, Dash lights, and four way flashers? When do I use those, or when do they turn on?
