If you are VFR at night and inadvertently get into the clouds and call for a pop up IFR clearance, should you move up or down to get on an IFR altitude? Neither – you should stay at the VFR altitude until instructed by ATC to change to an IFR altitude. This will at least give you 500' separation should there be an IFR plane above or below. What are some mandatory reports an IFR pilot needs to make? Compulsory reporting points if not in radar contact, any non-forecast weather conditions, loss of instruments, entering a holding pattern, missed approach. What direction is standard for holding? Right What is MEA and MOCA and the difference? Minimum Enroute Altitude guarantees obstruction clearance and adequate radio/navigation reception. Minimum Obstruction Clearance Altitude guarantees only obstruction clearance. If you were to loose communications, what is the correct transponder code and what do you do to try to fix it? Squawk 7600 and check for transmit lights. Check radio volume adjustments, try co-pilot side if equipped, try hand mike and cabin speaker, try cell phone, turn-up volume on nearby VOR station – ATC may try to call you on the VOR frequency. What route and altitude would you fly if you lost all communications? Last assigned route, if on a radar vector – direct to point being vectored too, expect further clearance route or flight plan route. (AVEF) Fly at the highest of (1) last assigned altitude (2) MEA/MOCA (3) expect further clearance altitude (if given a "wait time", do not start the climb until after you have waited the time – example … "climb 3000', expect 8000' in 10 minutes" FAR 91.185 What do the large and small numbers within a specific latitude/longitude grid on the Enroute Low Altitude Chart represent and how do they differ from the VFR Sectional Chart? The number on the IFR chart is the Off-Route Obstruction Clearance Altitude (OROCA). The OROCA represents the highest possible obstruction elevation including both terrain and vertical obstruction data (towers, trees, etc.). The number on the VFR Sectional Chart is the Maximum Elevation Figure (MEF). OROCA is computed just as the MEF except that it provides an additional vertical buffer of 1000' in designated non-mountainous areas and a 2000' vertical buffer in designated mountainous areas within the United States. Looking at the Enroute Low Altitude Chart, what is the quickest way to tell if an airport has an instrument approach? Blue and Green have approaches – Brown ones do not. (Green airport are more prevalent – these airport are published in the FAA TPP and the DOD FLIP. Blue airports are only published in the DOD FLIP.) What do the solid blue lines represent on the Enroute Low Altitude Chart? These are low altitude RNAV (GPS) only routes. They will always begin with a "T" prefix and a "TK" prefix for helicopter only routes. What do the numbers in the square box represent just below an airway line? Total distance for the route Why do some airway route intersections have a line across them and other do not? It looks like a sideways "T". This is to inform the pilot that the next leg segment has a change in the MEA. Look at Lexington VOR (HYK). Why do some of the outbound radials have a degree mark & other radials do not? The radials with the degree mark are numbers that could easily be read backwards when the chart is turned around; therefore, the degree symbol is inserted to keep the pilot from reading the radial incorrectly.
