MTPs • Aerodrome Markings • Runway Markings • Taxiway markings • Unservicability lighting • Wind Indicators • Aerodrome Lighting • Aerodrome Traffic Procedures • Joining • NORDO
Aerodrome Markings • Definitions: • Aerodrome: Any area used for the arrival, departure, or maintenance of aircraft. • Airport: An aerodrome with respect to which a certificate is in force • Manoeuvring Area: Areas intended for taking off, landing, and/or associated movement. Does not include apron.
Aerodromes Markings • Definitions (cont.) • Threshold: Denotes beginning of areas to be used for t/o and landing under normal circumstances. • Displaced Threshold: Area preceding threshold markings may be used for t/o and taxi but not landing. • Relocated Threshold: Area preceding threshold markings may be used for neither taxi nor takeoff/landing
Runway Markings • Numbering • Done by degrees magnetic in the Southern Domestic Airspace. In NDA, by degrees true. • Done from the pilot’s perspective. ie, the east end of an east-west runway will be numbered 27. • eg, A runway end with an orientation of 189 will be numbered 19. What about the other end? • Parallel r/w numbered L and R • To switch quickly between reciprocal r/w ends, use the 20-20 rule: Add 2 to one digit, subtract 2 from the other.
Runway Markings • Lighting • Only if portion of aerodrome is intended for night use. • Sides indicated by white lights visible at a distance of not less than 2 nm • Lights/markers to be no more than 60m (200 ft.) apart • Must be directly opposite one another • No fewer than 8 lights in a row (min 420 m/row) • White retro-reflective markers meeting same specifications may be used • In this case ends MUST be indicated by at least one white light/marker, visible for at least 2 nm
Taxiway Markings • Generally, painted with a yellow centerline • Lighting • If used at night, • Lights are BLUE • No less than 60m (200 ft.) apart
Unservicability Markings • Unserviceable Markings • When an aerodrome is closed permanently, all markings installed must be removed. Also applies to parts of manoeuvring area. • Except water aerodromes, red flags or cones must be used to denote closed portions of the manoeuvring area. • At night, red lighting to be used for closed manoeuvring area portions. • U/S Runways/Taxiways • Denoted by large, white or yellow Xs at each end • Where painting impossible, may use dye, or other material as appropriate.
Aerodrome Markings - Miscellaneous • Obstructions marked with red lights. • Must place warnings in public areas where a/c activity could pose hazard.
Wind Indicators • Except where wind direction may be obtained via radio or other indication, (eg, smoke) must have a w.d.i. • Must be truncated cone (ie, wind sock) • Visible from 1000 ft. (300m) above aerodrome • Painted in a conspicuous colour(s) (green generally not a good choice) • As, must be lit at night if a/d used at night • Removed immediately upon a/d closure
Traffic Procedures • Generally, all circuits flown at 1000’ AAE unless otherwise specified • Also, most circuits in Canada are left-hand • All turns made to left
Circuit Joining • Controlled Aerodrome: • Join when/where they instruct you to • May be straight-in downwind, mid-downwind, base, or direct to final approach
Circuit Joining • Uncontrolled Aerodrome: • Plan to land into the wind • Circuit must be joined mid-downwind following a descent on the upwind side • If required to cross field to go to upwind, cross over the field at 500’ above circuit height • Where no possible conflict, may join early downwind
Circuit Joining • Uncontrolled A/D (cont) • When operating at an aerodrome with a mandatory frequency, and the relevant ground advisory service is in effect, may join at more locations • That is, 45 degrees to downwind, or straight in on base and final • Also, MF zones require you to radio when established both downwind and final legs, as well as a 5-minute call prior to MF zone entry • (Not Required) MF Zone = 3000’ AAE, 5 nm around a/d
NORDO • NORDO: NO RaDiO • To communicate with you, ground operators may use light signals. • Permitted, (although perhaps not recommended) in all uncontrolled classes of airspace • Exception are MF zones; may still operate, provided: • Prior arrangements made with a/d operator • Ground advisory active when you go through • At any aerodrome, may only join on early or mid- downwind
