J’ai appris à piloter en région parisienne. C’était il y 7 ans maintenant. Lorsque j’ai commencé, le “transit nord du Bourget” qui permet de contourner Paris par le nord n’était déjà plus qu’un doux rêve ou un vague souvenir. On passait par 3 ou 4 points de report en VFR et sous clairance. Il fallait certainement voler droit, connaître et ne pas improviser. La trajectoire existe encore sur toutes les cartes.
“Oulala, même en demandant gentiment, tu sais depuis Septembre 2001, ce transit n’est plus du tout accordé” me disait-on au bar de l’aéroclub. Il y a bien quelques évènements exceptionnels (comme les anciennes journées aéronautiques de la femme) avec moulte dérogations et préparations. Il faut montrer patte blanche. Du coup, à part quelques rares privilégiés VFR, on fait le tour beaucoup plus au nord et on ne survole pas le Bourget. “C’est bien trop dangereux cela monsieur, vous comprenez”.
Dont acte.
Il y a quelques jours, j’ai reçu une notification pour un message posté sur le forum de PlusOne, mon autre aérclub à San Diego. Le sujet était “Taxiway Delta transition”. Et cela m’a vite rappelé ce message sur ce même blog. La “Taxiway Delta Transition” est une procédure publiée permettant de traverser dans un axe nord-sud au dessus… de l’aéroport international de San Diego (KSAN). Ah oui, j’oublie de préciser que cette procédure permet de passer à 1000 ft et qu’il faut être en contact radio 
Bon gardez tout de même le moral.
Je vous recopie le message du forum PlusOne qui vous explique comment faire une Lindberg Delta Transition South :
Delta Transition (South)
To make a smooth transition, on your initial call to MYF Tower, don't say you are a straight out departure, tell them you are doing the "Lindberg Delta Transition, South" so they can coordinate your left turn with in/out going traffic. MYF will give you an early freq change to 118.3. Tell Lindberg tower your alt & position (departed MYF at 1000)and say you want the "Delta Transition South". You don't have to ask for the Class B clearance, they know & will provide it. Lindberg tower may ask your intentions after crossing the Delta; tell them "after crossing the bay bridge, descend to 500 agl Westbound along the coastline to Point Loma, Northbound along the coast". They will contact North Island and tell them you are coming. When 'berg switches you to "Island Tower" 135.1(?) tell them the same thing you told 'berg. "over the bridge, wb @ 500 agl, nb thru Bravo". They are military and don't care why you want to go, keep it short, crisp and confident...Direction and Altitude is all they want to hear. Once you pass Pt. Loma and are northbound, Island Tower will send you back to Lindberg again. Ask "Lindberg Tower" for the "Bravo Route NORTH, 500 and below". They will expect you to stay over the water, 500 agl and below, and report reaching Crystal pier. If there is traffic between OB pier and Crystal pier, be prepared to circle @ or below 500 agl until you find them.
I flew the Delta taxiway transition last night and Lindberg was awesome. MYF tower was too busy to coordinate but I called Lindberg just east of Soladad and they gave me a quick clearance at 1500 AGL all the way to the bridge. Caught a great view of the Fedex heavy on short final. Island was happy to clear me to 500 AGL WB to Point Loma. When Island terminates around PLNU, don't forget to call Lindberg to get clearnance for 500' and below over the water. Awesome and easy sight-seeing flight for any level of flight experience.
Whiskey Route
Stay over I-8 @1000 msl westbound to the ocean. This route starts at either San Diego State or Qualcom stadium, depending on where you departed. After SEE freq change, tell MYF you want the "Whisky Route"; they will hand you off to Lindberg Tower @ Qualcom. Follow the freeway all the way to the coast. Usually 1000-ish descending to 500 agl. From MYF, in the Qualcom area ask for the Whiskey Route and expect a hand off to Lindberg.
Echo Route
"Echo Route" is the opposite of the Whiskey Route; Start with an eastbound turn at the Jetty by the roller coaster. Follow the San Diego River eastbound to I-8 Eastbound. If you are southbound along the coast, contact Lindberg at Bird Rock. Ask for "the Bravo Route Southbound, Echo route at the Jetty to MYF(or SEE)". If you are Northbound at Point Loma, when Island Tower sends you to Lindberg, ask for "Bravo Route Northbound, Echo Route at the Jetty to MYF (or SEE). Lindberg will hand you off to MYF at Qualcom and MYF will release you to SEE at Lake Murray. This route is very handy if the fog is closing in fast. I-8 is an easy landmark to follow and will usually lead you out of the fog. Bravo airspace visibility requirements are considerably less than what is required if you try to turn eastbound at Solodad.
