when flying on a heading of 0-180 degrees vfr, do you fly at even or odd thousands +500?

i believe it is even

    Sec. 91.159 - VFR cruising altitude or flight level.

    Except while holding in a holding pattern of 2 minutes or less, or while turning, each person operating an aircraft under VFR in level cruising flight more than 3,000 feet above the surface shall maintain the appropriate altitude or flight level prescribed below, unless otherwise authorized by ATC:

    (a) When operating below 18,000 feet MSL and --

    (1) On a magnetic course of zero degrees through 179 degrees, any odd thousand foot MSL altitude +500 feet (such as 3,500, 5,500, or 7,500); or

    (2) On a magnetic course of 180 degrees through 359 degrees, any even thousand foot MSL altitude +500 feet (such as 4,500, 6,500, or 8,500).

    (b) When operating above 18,000 feet MSL, maintain the altitude or flight level assigned by ATC.

    Thus, in answer to your specific question, the appropriate cruising altitude in VFR flight (above 3,000 feet agl) is odd thousands + 500 feet for magnetic course 0 - 179, and even thousands + 500 feet for magnetic course 180. Your heading is irrelevant, as course is equivalent to ground track, and wind corrections can cause your heading to be far different from your course.

    0-180 = fly odd thousand + 500

    181-259 = fly even thousand + 500

    Be careful though, these values are based on your ground track, not your compass heading as is commonly believed. Your airplane may be pointed 255 but if you're flying with a strong crosswind from the west, your actually ground track may be 005 or 010. Therefore, you must fly at odd thousand plus 500'. The examiner may try and trick you on that one!

    These apply for VFR navigation above 3000 feet msl.

    Muzza is correct. In Canadian airspace, above 3000'AGL,

    VFR

    0-179=odd thousand + 500'

    180-359=even thousand + 500'

    This is based on MAGNETIC TRACK.

    When your altitude is greater than 3,000 ft agl (above ground level) you should be at an odd thousands +500 feet in msl (mean sea level) altitude when your compass heading is between 0-180 degrees. In other words, if you were flying a compass heading of say 070 degrees, your altitude should be 3500, 5500, 7500, 9500..etc. Conversely, on heading of 180-000, your altitude should be even thounsands plus 500.

    Ask Center Control to verify your ground track or use a quality GPS, or if iPhone can do that for correct odd or even and request the proper altitude if Control gives an incorrect altitude in a busy area. You are responsible for anything happens and blaming the controller won't do much good in a crashed airplane after a mid-air. I had two mid-air incidents, one was a parachute jumper that got in the pattern on my first solo in a J-3, moved over for him and a few months later was nearly run down by a Cherokee overhead and 20 mph faster than me on short final in my Champ, instructor in the back seat, got into wing turbulence at 200 ft over a lake, 110 degrees rolled left, recovered at 100 ft and landed.

    000 to 179 is Odds + 500, 180 to 359 is Evens + 500

    >I< am allowed to ooperate in visibilites down to 800 meters by day, out of clouds. legally IMC conditions, maintaining VFR. this sort of operations has certain prerequisities, such as low probability of encountering other traffic, and reduced speed so that the IAS derived by visibility is less than 100, and minimum visibility 800 meters for helicopters, 1.5 km for fixed wings. we operate in compliance to JAA. your question has two layers , so to say. the first layer being the question of law. Yes you are allowed to operate in condition cited, provided the compliance with all applicable rules. the second layer being the practical part. if you need to ask such questions HERE.. you should not attempt to fly in such weather.

    One of the things I learned as a pilot to remember this is: "Odd people fly east." Remember this and odd altitude.

    Nope odd. Remember 'ODD people fly east'
