Slam-Dunk
We’ve all had ATC issue a descent clearance that came later than we would prefer. Pilots have labeled this a slam-dunk: throttles to flight idle, set the speed command to the fastest number ATC will allow, throw out the speed brakes and dive-dive-dive. This type of maneuver, how- ever, is suggested as a possible contributing factor in the 2013 crash of Asiana flight 214 in SFO. When necessary, a response of “unable” to ATC can solve a multitude of problems. If you attempt compliance, the slam-dunk will assuredly increase the feeling of being behind the airplane and possibly contribute to a serious error in judgment.
And finally, even if you fly the same approach often, a good review will help to catch changes to the approach or missed approach procedures. A commonly skipped check is a RAIM prediction if planning a GPS approach. If the number of GPS satellites available is 23 or fewer, RAIM availability must be checked using ground-based prediction software. Otherwise, you are reliant on your onboard system to discover insufficient RAIM at the last minute during the approach. Don’t forget to take note of inoperative components, such as the glide slope (making it a localizer approach) or part of the approach lighting, like runway centerline lights or the VASI or PAPI. Often the transition from landing to a high-speed taxiway is very busy as ground control issues a catalog of rapid-fire instructions. So, take note in advance of any closed taxiways, particularly ones you intend to use for exiting the runway.
Terror, Thrombosis, and Snakes
The view out our window is compelling. It’s easy to di- vert your attention from the cockpit to the world outside – the view is, after all, one of the reasons we fly. And it’s normal to be distracted by onboard events as well. Let’s not neglect preparation for the descent and approach, though. For a variety of reasons, this phase of the flight has become increasingly demanding with opportunities to commit errors of omission and commission at every turn (pun intended). Prepare for the descent and approach by increasing your alertness, circulating some blood and warming up your brain. Be careful out there. None of us want our boredom in cruise to be followed by minutes of terror or arterial thrombosis. Unless that is, you carry some stimulants and a snake in your kitbag. If so, never mind everything I said.
