Because there is no engine shut down and start up, I use the beacon and Nav lights to indicate this. Basically, when I spawn, I immediately turn all my External lights off and turn all my cabin lights on ( seat belts, smoking), while I make my flight plan, as you know, sometimes this can take a while especially in a new region with unfamiliar airport tags. So for G_d’s sake don’t ask me for intentions when my lights are ‘off’ I AM PLANNING AND SETTING UP FLIGHT SYSTEMS and I like to take my sweet time doing it. Once I have finished flight planning, I set flaps and desired altitude, then I turn on beacon light and request push back. After pushback, I turn on my Nav lights and tell ground I am ready to taxi. Once taxi clearance is received, I turn on Landing lights and move to the run way. While in line if there is no aircraft behind me, but aircraft before me, I ‘flash’ my strobes in a slower pattern. IE: on - 1,2 - off; repeat ( sort of ‘flash, flash’ pause, ‘flash, flash’) untill another plane comes up behind be then they stay off untill I am actually on the runway when they are switched on. ( mainly for the benefit of night flyers as they have such a retarded lighting experience to begin with, with no internal cockpit or instrument lights, no taxi lights, no taxiing lights either) At 9,000 I turn off landing lights. At desired alt and heading, I turn off cabin lights ( yeah, I let them smoke - lol). On landing, 2 mins or so prior to initial decent I turn on cabin lights and head to 10,100. Drop speed to 240. Then I begin decent to final and turn on landing lights at 10,000. After landing and before contacting ground for parking clearance once off the runway hold threshold I cut my strobes. At the parking bay, I cut landing lights, turn off cabin lights, cut Nav lights, cut beacon light, thank ground, and clear my flight plan. Then I either exit, or replan. At least this is what I do.
