Recuerde las 5 T´s para vuelo IFR

The 5 T’s
Turn, Time, Twist, Throttle, Talk -Taught to generations of instrument students, it details the actions to take at various points in an approach or entry into holding. Not all of the T’s will be needed at every point, but running through the list will save you from an embarrassing omission.
·       Turn – turn to the desired heading. You may need to turn to an intercept heading to get on the desired radial or bearing.
·       Time – start your timer, if needed.
·       Twist – twist the OBS to the proper setting, either required radial or the reciprocal to eliminate reverse sensing.
·       Throttle – reduce your airspeed
·       Talk – if asked to report, do so.

TITS -the mammary gland check, used to set a navigation radio and not forget something critical while doing so.

·       T – tune in the correct frequency
·       I – identify the VOR or NDB. That Morse code is there for a reason, so use it to make sure you have tuned in a properly working VOR or NDB.
·       T – twist the OBS to the correct setting
·       S – select the correct source, GPS or land-based VOR. Since the advent of GPS, the most common installation relies on a single VOR head to display either GPS information or VOR information. Make sure you know what is driving the VOR display.

One of the most common mistakes I see, as an instrument instructor, is failure to select the proper source. Some GPS units will switch from GPS to VLOC if the active frequency is a localizer, but don’t depend on the box to do it for you. You are PIC in the airplane, not the GPS, so make sure the signals driving the VOR display are coming from the desired source.

  1. Sigo pensando que el viraje, por ejemplo en un viraje base, el twist debe hacerse antes que el turn, de manera de tener un scan apropiado en está fase donde el piloto con poca experiencia tiene a no prestar atención a su escora sobrepasando la máxima permitida en vuelo IFR (30°) si mientras lo realiza, ejecuta un cambio de frecuencia o de flecha en el HSI.

  2. Yo pensaba igual, pero no hay que olvidar que todo esta pensado en función de la aviación comercial: Cuando uno vuela con Autopilot conectado, y comienza el viraje al nuevo rumbo, se inicia moviendo lentamente el HEADING BUG en el sentido del viraje....
