Radio Comms - what 5 over 5 actually means

The signal quality is reported on two scales; the first is for signal strength, and the second for signal clarity. Both these scales range from one to five, where one is the worst and five is the best. The listening station reports these numbers separated with the word "by". Five by five therefore means a signal that has excellent strength and perfect clarity — the most understandable signal possible.

FROM THE TOWER SIDE

 

Into the circuit

It is already the end of January and almost everyone is back from their holidays as it is sometimes going crazy at Cape Town International.

It is back to holding outside the CTR for far too long to your liking to wait for the arrival and departure sequence to finish. When you finally get to downwind, you probably need to orbit a bit more to get the last schedule traffic in or out. That’s when it is always a good idea to keep that circuit as tight as it is safely possible. Most of the regulars here from Cape Town normally do know that ATCs will find it easier to squeeze you in from close downwind. If you are too wide, it sometimes just take too long for you to land and vacate before the next schedule catch you up from behind.

Not too long ago, a light aircraft based at Cape Town Intl. was given an instruction to land-after the traffic vacating the runway at Charlie intersection. The pilot then proceeded and landed the aircraft after the Charlie intersection, obviously misunderstanding the ATC instruction. This then lead to extended runway occupancy time since they had to vacate at the end onto Bravo taxiway. The aircraft following was a schedule aircraft and fortunately agreed to execute a land-after with the light aircraft about to vacate on Bravo taxiway. Without the confusion, the light aircraft would have vacated the runway at Charlie taxiway and entered Hotel taxiway by the time the following aircraft touched down on the runway.

There have been instances where GA pilots acknowledge the instruction to plan for Charlie taxiway on landing and completely overshoot the Charlie intersection or pass it at too a high speed to turn off. Recently a pilot overshot the intersection in his light aircraft and unfortunately on that occasion the following schedule aircraft had to execute a missed approach.

Tell ATC if you are not comfortable or unable to fly close circuits or to land deep to vacate at an intersection when you ask for joining. This will enable ATC to make safer decisions in the airspace we battle to help keep safe. There are pilots out there, and we have an idea of the voices, which really make life easier for all of us with their professionalism and skill. I am sure it is the same from you’re side too towards ATCs. Most ATCs work really hard to let GA traffic in and land in between arriving and departing schedule traffic. The rules of the company and the SACAA dictate that schedule traffic has absolute priority over GA traffic. When things go wrong, ATC has to explain why they gave priority to the GA traffic and not the schedule traffic. That is why it is important to always keep up your situational awareness and work with ATC.     

Things can go crazy within a moment’s notice and both ATC and pilots need to be aware that we cannot afford to make mistakes. Most of the time it is the simple things that cause unsafe situations for example, lack of situational awareness, non-compliance with ATC instructions, incomplete and uncorrected read-backs, pilots and ATCs alike.

DENSITY ALTITUDE

Caught out by the density altitude recently? Temperature and humidity have a huge effect on density altitude as witnessed recently at Morningstar where the high temps.and humidity played havoc with what pilots are accustomed to. Using the DA calculator (see right) the density altitude at Morningstar was over 3000ft! This reduced aircraft engine and airframe performance to such an extent that a few pilots even had to abort take off.

The conditions even resulted in carb icing! Get with the programme and familiarize yourself with the DA calculator to see just how radically high temperatures and humidity can affect your aircraft.

When last did you do a really thorough pre-flight inspection?
