More than just North America

While most of Direct Approach’s work is in North America, we also have extensive experience with designing IFR approaches and departures around the world.

We have designed new procedures based upon PANS-OPS in Australia, Peru, and The Republic of Guinea in Western Africa.

For Rio Tinto at Beyla, Guinea we created the first GNSS based approaches and departures in that country. These were created in cooperation with HART Aviation, l’Agence de la Navigation Aerienne (ANA) and flight checked together with ASECNA (the Agency for Aerial Navigation Safety in Africa and Madagascar ).

Also on behalf of Rio Tinto and HART Aviation we designed a high altitude helicopter approach near their exploration site at La Pampa, Peru.

Would your flight operations benefit from the consistency and reliability offered by having GNSS based IFR approaches and departures? Direct Approach can design to all of the recognized standards contained in ICAO’s PANS-OPS, FAA’s TERPS, and Canada’s TP308.

Sturgeon Falls – West Nipissing General Hospital

Direct Approach recently completed a periodic review of the COPTER RNAV (GNSS) 193° instrument approach to the West Nipissing General Hospital helipad at Sturgeon Falls, Ontario.

All sponsored instrument approaches in Canada, regardless if they are published in the Canada Air Pilot (CAP) or Restricted Canada Air Pilot (R-CAP), must undergo a full periodic review every 4 years to ensure approach design criteria and regulatory compliance. This review also ensures that all obstacles, either manmade or natural, or properly accounted for.

In the case of WNGH, it was found during the flight check and post flight check review that the normal land use documentation for the town’s new water tower was not properly completed and therefore this obstacle was not accounted for. This was remedied, and an adjustment to the approach subsequently made.

The approach is therefore renewed for another 4 years to serve the emergency medical air access needs of the West Nipissing region.

Direct Approach is proud to have been of service to the Sturgeon Falls / West Nipissing General Hospital.

Vancouver Harbour 5 Departure

Direct Approach recently completed the latest regulatory review of the Vancouver Harbour (Heli) Public – CBC7 – Harbour Five Departure.

All sponsor supported instrument flight procedures must be routinely reviewed for accuracy and criteria compliance. In the case of the Helijet sponsored Harbour 5 Departure, there is no helicopter departure design criteria. Therefore a special Transport Canada exemption has been used to permit the use of prominent geographic points, the Shoal Marker and Lions gate Bridge (mid span), to substitute for the normal Departure End of Runway (DER). From there a standard heading to intercept a VOR track type construction is used.

With the renewal of this specialized helicopter IFR departure procedure, Helijet International continues to maintain its operational advantage of all weather operations between its Vancouver and Victoria Harbour bases.

Vanderhoof, BC – New GPS approaches and departures

On 15 December 2011 new GNSS approaches and departures, which were developed by Direct Approach, were published in the Canada Air Pilot. As described in an article recently published in the Vanderhoof Omineca Express ( http://www.ominecaexpress.com/news/137100488.html ) these new instrument approaches will greatly improve all weather air access to the region.

Direct Approach congratulates the District of Vanderhoof on being proactive in enhancing aviation safety and improving the level of service to their airport.

Neepawa – New GNSS approaches

On behalf on our client HyLife Foods, Direct Approach was commissioned to design two new RNAV GNSS approaches for Neepawa Manitoba. The Neepawa airport is located approximately 26 nautical miles north east of Brandon, and 90 nm west of Winnipeg. It has a single paved and lighted runway 3508 ft in length.

 Two standard “T” style GPS “LNAV” approaches were designed, one to either runway end. The proposed approach minima for the RNAV (GNSS) RWY 04 is approximately 540 feet HAT (height above touchdown), while the RNAV (GNSS) RWY 22 approach HAT is slightly lower at approximately 450 ft.

 Direct Approach completed the standard flight verification on December 19th 2011. The approaches will now be submitted for publication in the Canada Air Pilot (CAP). These approaches, once published by Nav Canada, will provide improved all weather access into Neepawa, and not only for HyLife’s current flight operations, but for all IFR capable flights.

 Direct Approach congratulates HyLife on their significant efforts to improve the efficiency of their flight operations, as well as to improve their overall flight safety through establishing these new IFR GNSS approaches!

Thor Lake, NT

On behalf of Det’on Cho Logistics and Avalon Precious Metals, Direct Approach Consulting was commissioned to design a new GPS instrument approach to the Thor Lake (NT) runway.

Thor Lake is an exploration site currently with a 1006 ft private gravel runway. There are plans to lengthen the runway once the site actives increase, with the potential for much larger aircraft.

Direct Approach assisted CBR Technologies in having the aerodrome registered and published in the Canada Flight Supplement (CFS). Normally only runways over 1500 ft in length are registered and published in the CFS. However because registration is required to obtain an ICAO site identifier, a special case to have this site processed was required. The Thor Lake registration is complete, and the new identifier CTH2 issued.

The straight-in RNAV (GNSS) RWY 23 approach is a standard “T” design GPS approach to a minimum descent altitude (MDA) of 512 ft above aerodrome elevation, or just above the minimum permissible for an aerodrome that does not meet any TP312 OLS standards.

A standard flight check was completed on September 7th 2011 using a DHC-6 “Twin Otter” from Air Tindi. The approach checked perfectly, and is ready for submission to Nav Canada for publication in the R-CAP.

Direct Approach Consulting provides all types of instrument approach and departure design services, specializing in GNSS (GPS) fixed wing and helicopter approaches, and is qualified in TP308, TERPS, and PANS-OPS criteria. More information can be found at http://www.directapproach.ca

Edit: The unfortunate recent air accident at Yellowknife involving Thor Lake personnel in no way involved the new instrument approach described here.

Creston, BC (CAJ3)

Direct Approach recently completed the required periodic review of the Creston BC (CAJ3) instrument procedures. Included in this cyclic review were the RNAV (GNSS) RWY 15 approach, and BOXAT RNAV (GNSS) Departure. Both these are published in the Restricted Canada Air Pilot (R-CAP)

Transport Canada regulations required that all R-CAP approaches and departures undergo a full review every 4 years. In addition to a review of the TP308 design criteria, this also includes the requirement to complete a flight check.

These GPS based approach and departure procedures have been updated and will be re-submitted to Nav Canada for renewal.
