Hey everyone, new to the site. Had a question about a couple of interview questions I read on a gouge for Comair. Not sure if I am understanding the questions correctly. Here goes, what is blueline on the airspeed indicator and does it ever change? My answer would be blue line is the best rate of climb single engine, or will give you the slowest "drift down" speed. It is based on max T/O weight, clean, standard day conditions. As you deviate from these conditions, your rate of climb will in turn change. Rate of climb in terms of ft/min will increase with appox. 50% of the change in weight. For example, A 20% reduction from MTOW will give you Approx a 10% increase in VYSE. On the other had, NO, blueline is always the same indicated airpeed as far as the airspeed indicator is concerned. Which is it?
The other question I had was " Why is adf and radar required on the LGA ils?" My answer would be because you need the adf to navigate LOM/Hold. Radar is required anytime a portion of an approach is not navigable by means of a navaid. At LGA, the plates say the VOR is temporarily moved and to check the Notams. Is this why radar is required or am I retarded?
Thanks for any responses.
