EXEMPTION FROM STANDARD 5.2.10.2 OF THE AERODROME STANDARDS AND RECOMMENDED PRACTICES (TP312, 5th Edition) MADE PURSUANT TO SUBPARAGRAPH 302.07(1)(a)(i) OF THE CANADIAN AVIATION REGULATIONS

Pursuant to subsection 5.9(2) of the Aeronautics Act, and after taking into account that the exemption is in the public interest and is not likely to adversely affect aviation safety, I hereby exempt Canadian airport operators from the requirements set out in Standard 5.2.10.2 of the Aerodrome Standards and Recommended Practices (TP312, 5^th Edition) made pursuant to subparagraph 302.07(1)(a)(i) of the Canadian Aviation Regulations, subject to the following conditions.

Standard 5.2.10.2 of the Aerodrome Standards and Recommended Practices (TP312, 5^th Edition), including its referenced Figure 5.6(b), sets out the requirement for pairs of Touchdown Zone (TDZ) markings.

PURPOSE

The purpose of this exemption is to allow all Canadian airport operators to operate a runway with safety standards pertaining to the number of TDZ marking pairs that are consistent with the previous edition of TP312 (4^th Edition) and with current internationally accepted standards until such a time the 5^th Edition is corrected.

APPLICATION

This exemption applies to Canadian airport operators operating a runway for which TDZ marking pairs are required to be positioned pursuant to standard 5.2.10.2 of the Aerodrome Standards and Recommended Practices (TP312, 5^th Edition).

This exemption ceases to apply to the Canadian airport operator who breaches a condition of the exemption.

CONDITIONS

This exemption is subject to the following conditions:

1. The airport operator shall ensure that the number of pairs of TDZ markings disposed about the runway centerline related to the declared Landing Distance Available (LDA) is as presented in Table 1 and Figure 1 below, whereby the pairs of stripes are to be positioned at a longitudinal spacing of 150 m (±1.0 m) beginning from the threshold except that pairs of TDZ markings coincident with or located within 50 m of an aiming point marking are deleted from the pattern;
