A Cessna Citation Mustang CE-510 Very light jet (VLJ) makes a visual approach and landing to runway 31 at the Nashville, Tennessee airport. Once cleared for the visual approach we follow a Boeing 767 visually to the runway. In this case, a wake turbulence encounter while following the heavy 767 is a very real concern. Its wake vortices are an invisible hazard and flying into the vortices of an aircraft of the size of the Boeing can cause the temporary loss of control or worse for a smaller aircraft. Our strategy to deal with this possibility is to stay above the wake vortices of the preceding aircraft. These vortices sink at 300 to 500 ft per minute and can last up to 2 minutes before dissipating. Since we can’t actually see these spinning horizontal tornado like columns of air that come off the wingtips of the heavy we stay one dot high on the glide slope as we descend to the runway. There is a fair amount of air traffic control communications in the video. Another interesting thing about the video is that this landing is just before the sun comes up. You can still see all the airport lighting and the two bright flashing lights on the approach end of the runway are the Runway End Identifier Lights (REIL’s) their purpose is to aid in identifying the end of the runway at night when the runway is surrounded by bright city lights.
The Cessna Citation 510 is a 4 passenger business jet. It’s powered by two Pratt & Whitney PW615F turbo fan engines and has a max ramp weight of 8,730 lbs. It can climb to 41,00 ft and cruise at 340 ktas with a range of 1,150 NM. Apologies for typo, the mustang has the Garmin 1000 avionics package.
