FAA proposes draft B-737 Max Training only for US carriers & registered aircraft only

Image
The FAA has released a flight standardisation boardreport relating to B-737 Max pilot training. Soon after, an addendum was issued too. While FAA has clearly stated that the training required in the FSB is mandated for US air carriers & US registered aircrafts, other aviation authorities must take their own action for the return of the B-737 Max.Question, will the Indian regulator follow a systematic process of change management and not be rushed into the re-entry process? Will the FSB report adopted in toto and will the regulators draft training requirements be put out for public comments?
The key highlights are quoted below from the FAA website as of 7th Oct 2020:While this is an important step, several key milestones remain:Final Design Documentation and Technical Advisory Board (TAB) Report – The FAA will review Boeing’s final design documentation to evaluate compliance with all FAA regulations. The multi-agency TAB will also review the final Boeing submission and issue a f…

Much defended, Kozhikode Runway RESA & Runway Strip do not meet ICAO standards

RESA
 

The Runway End Safety Area is mandated by ICAO in Annex 14 as a standard. Following is the definition:

An area symmetrical about the extended runway centre line and adjacent to the end of the
strip primarily intended to reduce the risk of damage to an aeroplane undershooting or overrunning the runway.


ICAO Annex 14 requirements



Kozhikode airport design of the RESA has used the width of the turn pad at both ends of the runway to meet the 90m, double the width of the runway requirement of ICAO Annex-14. Unfortunately, ICAO  Annex-14 as per definition specifically defines RESA with the terms Extended Centerline and Symmetrical.

This implies that RESA must extent 45m either side of the extended centerline all the way till 240m. The Kozhikode RESA does not meet the ICAO standard by 10 m.

Technically if 10 m is significant, Kozhikode is not a RESA as per ICAO standards. 

Recommendation.— The width of a runway end safety area should, wherever practicable, be equal to that of the graded portion of the associated runway strip.

ICAO Annex-14 Extract on width of the Runway Strip


Width:

Width of runway strips
3.4.3 A strip including a precision approach runway shall, wherever practicable, extend laterally to a distance of at
least:
140 m where the code number is 3 or 4

Legal meaning of Practicable means available and capable of being done after taking into consideration cost, existing technology, and logistics in light of overall project purposes.

Runway Excursion Risk Reduction ICAO Aerodrome Best Practice
 

Airport Authority of India has issued a tender in 2019 for grading of the area beyond the runway strip with 330 days set as the work period. This clearly indicates that a 140m runway strip as mandated by ICAO is practicable but was not implemented for reasons which need to be probed. The tender amount seems miniscule compared to the cost involved though.

Tender for grading work on the runway strip

Therefore the Kozhikode runway is compliant for 1&2 aircraft's only since the Runway strip is 75 m either of the centerline and the Annex 14 requirement is 70m.

The runway is non compliant for aircraft's like B-737, A-320 and bigger.

  1. They can reduce RW length by ten meters and add it to RESA. But that won't solve the problem of tailwind landing.

    1. RESA is a distraction, why is there a big debate about it. Focus on why SOP's don't work. If it is about RESA then technically, they are falling short of 10m width.

  2. CCJ has RESA of 93*90 on one end and 92*90 on the other end which Is twice the Width of runway (45mts). 10 mts shortage ? It also looks symmetrical with 45 mts on either side of the centreline. Correct me if I am wrong.
