CRUISING ALTITUDES

CRUISING ALTITUDES WITHIN CONTROL AREAS AND ZONES--Aircraft at or more than 3000 feet above the
surface within control areas and/or control zones must be flown at odd or even 1000-foot levels uppropiate tu the direction of
flight. “Odd and even” indicators are shown on Coust and Geodetic Survey Radio Facility Charts.

The following rules will govern the altitude at which aircraft shall fly when making flights along civil airways:

Green and Red Airways

Eastbound flights. Aircraft making good a true course of from 0° (or 360°) to, but not including, is)’ along a green or ved
civil airway‘shall fly at an ODD thousand-foot level above sea level (such as 8000, 5000, or 7000 feet)

Westbound flights, Aircraft making good a true course of from 180° to, but not including, 360° (or 0*) along a green or red
civil airway shall fly at an EVEN thousand-foot level above sea level (such as 2000, 4000, or 6000 feet).

Amber and Blue Airways

Northbound flights. Aircraft making good a true course of from 270° to, but not including, 90° along an smover or blue civil
airway shall fly at an ODD thousand-foot level above sea level (such as 5900, 5000, or 7000 feet).

Southbound flights. Aircraft making good a true course of from 90° to, but not including, 270° along an ember or blue civil
airway shall fly at an EVEN thousand-foot level above sea level (such as 2000, 4000, or 6000 feet).

CRUISING ALTITUDES OUTSIDE CONTROL AREAS AND ZONES—When the flight visibility ts less than
three miles, aircraft must be flown at an altitude appropriate to the magnetic course as illustrated below.

MAGNETIC HEADINGS

VISUAL FLIGHT PLANS

The Civil Air Regulations do not require that a VFR flight plan be filed for a VFR flight. However, the filing of such a flight
plan is desirable, and the CAA urges that VFR flights be covered by flight plan whenever practicable as such filing materially
assists in search and rescue operations if such action becomes necessary. Flight plans may be submitted to the nearest CAA

airway communications station either in person or by telephone. Flight plans may be filed by radio if no other means are
available but this practice should be avoided whenever possible to reduce congestion of radio channels.

If filing the flight plan, the pilot should state the name of the CAA communications station with which he wil! close his flight
plan. If the destination is not served by a CAA communications station, or isin Canada or Mexico, the method by which the
arrival report will be filed must be clearly understood by all concerned, VFR flight plans are transmitted via CAA communica-
tions facilities only to the: CAA communications station with which the pilot has stated his arrival report or closing of
flight plan will be filed. One hour after the estimated time of arrival, if no notice of arrival is received, queries are sent out over
CAA communications systems to determine the location of the aircraft. If no information concerning the aircra‘t is obtained
after an exhaustive communications inquiry, search and rescue operations are inaugurated. In as much ar the government
may be put to considerable expense in determining the location of aircraft when an arrival report is not filed, it is vitally
necessary that all pilots make certain that notice of arrival is filed. If flight is terminated prior to reaching the point of intend-
ed destination specified in the flight plan, pilots should contact the nearest CAA communications station and the request that

an arrival report be transmitted over CAA facilities to the CAA communications station with which the pilot stated the arrival
report would he filed.

Pilots of aircraft operating on VFR flight plan who desire to make flight progress reports, should include in the report the
phrase: “VFR FLIGHT PLAN FROM (blank) TO (blank).”

The flight plan shall contain the items listed under INSTRUMENT FLIGHT RULES - Flight Plan, except “Alternate
Airport” and except that a visual flight rule flight plan should always specify “VFR” as a cruising altitude, The use of this
term in lieu of an actual altitude indicates that the pilot intends to fly in accordance with Visual Flight Rules. Aircraft may
he operated in accordance with VFR above a well defined cloud or other formation provided, climb to and descent from such
“on top” flight can also be made in accordance with VFR.
