Challenges during localizer performance with vertical guidance (LPV) approach procedures

Approach procedures that offer localizer performance with vertical guidance (LPV) minima are found at many airports across Canada. Despite the occasional challenge, LPV procedures continue to markedly increase airport accessibility and offer pilots and aircraft operators a safe way to carry out vertically guided approaches to many runways in Canada.

Are you planning an air show this summer?

Canadian airshows, or “special aviation events,” truly do come in all shapes and sizes and are as diverse as aviation and the people attending. CAR 603.01 states that you cannot conduct a special aviation event other than a fly-in unless you have been issued and comply with the conditions of a special flight operations certificate (SFOC). Not sure whether your aviation event needs an SFOC? As with most things in aviation, if you aren’t sure, ask the experts!

TSB Final Report A22C0016—Collision with Terrain

Cessna 208 Caravan. Continued flight under VFR into areas with reduced visual cues, such as areas with deteriorating weather or whiteout conditions, can lead to spatial disorientation and potentially a loss of control. All pilots—no matter how experienced they are—need to plan ahead and consider strategies to avoid such conditions, as well as have alternate plans should such conditions be encountered.
