Sandel Tech Note on GTN Software

From Sandel Product Support: Charlie here, I have found a problem with the current software level 5.0 on the Garmin GTN 750/650 series units when interfaced to Sandel displays. The problem is when you have to configure any GAMA output port.

Transport Canada Aircraft Certification Policy Letter (ACPL)

Posted Wednesday, August 14, 2013 Posted in Canada TAWS Mandate

Terrain Awareness and Warning System

Transport Canada Aircraft Certification Policy Letter (ACPL)

1.0 Purpose

1.1 The purpose of this Aircraft Certification Policy Letter (ACPL) is to provide Transport Canada Aircraft Certification personnel, including delegates with guidance for the certification of Terrain Awareness and Warning System (TAWS) and Enhanced Ground Proximity Warning System (EGPWS) on Canadian registered aircraft. This policy is provided with the consideration that there is no firm TSO standards or advisory material for the certification of TAWS at the present time.

1.2  For the purpose of this Policy Letter, the term EGPWS is meant to be used interchangeably with TAWS. This Policy Letter is not intended for the certification of conventional Ground Proximity Warning System (GPWS).

Canada Gazette Regulatory Impact Analysis Statement

Regulations Amending the Canadian Aviation Regulations (Parts Ⅰ, VI and VII)

Canada Gazette Regulatory Impact Analysis Statement

Issue: From 1977 to 2009, 35 airworthy aeroplanes were flown into the ground while under pilot control. The aviation industry refers to these as controlled flight into terrain (CFIT) accidents. There have been 100 fatalities and 46 serious injuries as a result of these CFITs. To date, risk information alone has not motivated all of the Canadian aviation industry to voluntarily equip key passenger aircraft with existing technologies that would help mitigate risks associated to CFITs.

Description: The proposed regulatory amendments would introduce requirements for the installation of Terrain Awareness Warning Systems (TAWS) equipped with an Enhanced Altitude Accuracy (EAA) function in private turbine-powered aeroplanes configured with six or more passenger seats, excluding pilot seats, and in commercial aeroplanes configured with six or more passenger seats, excluding pilot seats. Operators would have two years from the date on which the Regulations come into force to equip their aeroplanes with TAWS and five years to equip with EAA.

Cost-benefit statement: The vast majority of Canadian passenger aeroplane operators already respect these proposed amendments. The present-value cost of equipping and retrofitting the remainder of the fleet with TAWS and EAA is estimated to be approximately $59M ($43M for TAWS and $16M for EAA). The present-value benefit (e.g. prevention of fatalities, serious injuries, and material loss) is estimated to be approximately $216M. These proposed amendments should yield a net benefit of approximately $157M over a 10-year period from full implementation.

Business and consumer impacts: There would be some cost associated with the implementation of these proposed amendments, but the risks associated with CFIT accidents would be reduced, resulting in fewer deaths, serious injuries and material loss. Businesses and consumers would therefore benefit from the increased safety of aircraft. Moreover, airlines travelling to the United States and to the European Union would be

in compliance with similar regulations in those jurisdictions, strengthening Canada’s ability to compete economically in those markets.

Domestic and international coordination and cooperation: These proposed amendments would align the Canadian regulation with those of other jurisdictions. The United States, the European Aviation Safety Agency (EASA) and the International Civil Aviation Organization (ICAO) have all introduced legal requirements and standards regarding TAWS. Canadian aircraft operators operating in other jurisdictions are expected to comply with the more restrictive regulations of these jurisdictions. Impacts on imports of new aircraft would be minimal.

Avionics Upgrades

Article by James Careless via Rotorcraft Pro, August 2013 

The Bell 212 Twin Huey is a venerable rotorcraft, with 45 years of history underits blads.  Unfortunatley, a decades-old helicopter cockpit experiences a lot of wear and tear.  Add analog 'steam gauge' displays, and the result can be a visually shabyy, technologically-obsolete cockpit that can compel all but the hardiest of helicopter enthusiasts to pay more for brand new aircraft - even if the older model still has lots of life in it!
