Right hand downwind for Tenerife-South ✈️🇪🇸
More views from the Las Palmas trip over the past two days, I flew as a passenger with @binternt from Gran Canaria to Tenerife-South. Seen here whilst sat in a great window seat is the mountain ‘Pico del Teide’ at 3,718m / 12,918ft. 🇪🇸✈️
You asked for it, so here comes a #weatherwednesday#flightplanning example!
For a general overview, I checked satellite images and SIGMET against today‘s North Atlantic Tracks (A). After a glimpse at the HIL (hold item list) I knew my #plane was fully fit for #flight (B) - but that particular #aircraft was not PBCS (performance based communication / surveilance) certified, so I wouldn‘t be able to plan tracks S/T/U.
Next, I checked NOTAM and #airport weather for departure, destination and possible Alternate #aerodrome (C) - eventually selecting CGN as 1st ALTN (D), given all operating minima were met (D).
After adjusting the ZFW (zero fuel weight) and setting the CONT (contingency fuel) policy, I performed a brief pre-calculation of take-off / landing performance, finding no restriction.
Now, it was route planning time! I routinely calculated a minimum fuel, charge, time track, plus the available NAT tracks (pic 2, A). Murphy‘s law struck: most efficient routes were tracks Y -Z...which looked fine on the significant weather chart (SIGWX, A). However, once again weather didn’t stick to the forecast, and thunderstorms with tops above #flightlevel 400 (B) affected those optimum tracks.
I quickly ruled out a routing slightly further north, as severe turbulence was forecast around Newfoundland (see A). A routing along the east coast and a northern track proved some 30 mins longer (let alone the additional fuel/cost).
So I tried some options further south - and there it was: the best alternative I‘d get! At just some 3-5 mins slower (C), the red route (A) was south and clear of both tracks and thunderstorms (B) and turbulence.
I checked on possible enroute NOTAM/restrictions (none) and adjusted the flight profile to avoid the tropopause (as this tends to be bumpy; D).
Then, I released the #flightplan, attaching some #briefing remark for the #pilot and the NAT track message.
So all done? Well, no - there was another Florida #flight waiting to be planned 🤷🏼♀️
Did you know the fourth Freedom of the Air is the right or privilege, in respect of scheduled international air services, granted by one State to another State to take on, in the territory of the first State, traffic destined for the home State of the carrier?
Who knows how many there are? 🤔
