Flight training organisation: ATO or DTO file

Flight training organisations must identify their course scope before preparing organisational approval or declaration. ATO and DTO frameworks cover different activities and requirements. French DGAC and Swiss FOCA guidance distinguish their relevant routes; the Swiss legal framework must be read in its applicable version. Connect syllabi, responsible functions, instructors, aircraft, sites and manuals. This organisational dossier does not establish an individual trainee’s licence.

Example question

Which courses and privileges belong to the organisation's actual scope?

Julie Illustration

France: map each licence course and rating course to the organisation’s documented privileges. Switzerland: identify the actual OFAC scope and any limits; teaching a rating to an existing professional pilot is not the same task as providing every professional-licence course.

Answer

Does the proposed course activity require ATO approval or permit a DTO declaration?

France: compare actual courses with ATO approval or the limited DTO.GEN.110 declaration scope. Switzerland: make the same course-based analysis under the aircrew provisions incorporated by the air agreement; a school’s marketing description does not determine its permission route.

Answer

What training programmes and syllabi must be submitted?

France: ORA.ATO.105 addresses ATO programmes and manuals, while DTO.GEN.230 requires a programme for each relevant course. Switzerland: use the incorporated scope and actual submission, separating an ordinary programme from any branch requiring specific approval.

Flight training organisations must identify their course scope before preparing organisational approval or declaration. ATO and DTO frameworks cover different activities and requirements. French DGAC and Swiss FOCA guidance distinguish their relevant routes; the Swiss legal framework must be read in its applicable version. Connect syllabi, responsible functions, instructors, aircraft, sites and manuals. This organisational dossier does not establish an individual trainee’s licence.

Answer

How are aircraft, sites and training facilities tied to that scope?

France: connect aircraft, relevant devices and operating sites with the courses actually provided. Switzerland: preserve the same course-to-resource map and authority records. An advertised aircraft or location is not proof that it belongs to the permitted scope.

Answer

What manual versions and changes require authority attention?

France: distinguish drafted, submitted and retained manual versions; a certificate change requires the relevant application information under ORA.ATO.105. Switzerland: compare the applicable incorporated change route and actual OFAC correspondence rather than importing every later EU amendment automatically.

Answer

Which surveillance and training records demonstrate continuing organisational control?

France: link surveillance findings, responses and training records with responsible roles and completion evidence. Switzerland: retain the corresponding authority follow-up and open observations; an internally closed action is not automatically an accepted response or an extended approval.

Answer

What separates the school's permission from an individual student's licence?

France: the school’s approval or declaration concerns its organisation and course scope, while the student applies separately for a personal licence. Switzerland: preserve the same distinction with OFAC; course completion alone does not issue the student’s title.

In order

Which preparation steps come first?

Editorial preparation order, not a popularity or success-probability ranking. Rank preparation by dependency: course scope, syllabi, responsible functions and resources, then controlled versions and organisational follow-up.

  1. Define the courses and ATO or DTO route

    Actual course scope determines the preparation file. A programme based on the wrong route must be corrected before gathering resource evidence.

    EASA: Easy Access Rules for Aircrew : ORA.ATO.105, DTO.GEN.110, DTO.GEN.115, DTO.GEN.230DGAC : organismes de formation aéronautiqueLoi fédérale sur l’aviation (LA), RS748.0 : 60Accord Suisse–Communauté européenne sur le transport aérien, RS0.748.127.192.68 : 1

  2. Connect each course with a controlled programme

    Objectives, syllabus and version make the intended training concrete. This relationship precedes assigning instructors and aircraft to that training.

  3. Document responsible roles and instructor qualifications

    Each course needs identifiable, evidenced roles. An individual instructor qualification alone does not establish the school’s organisational permission or full course scope.

  4. Map aircraft and sites to the programme

    Resources are examined against the actual course requirements. An unallocated inventory cannot show which training activity the proposed resources support.

  5. Reconcile versions, changes and follow-up findings

    With scope established, compare submitted versions and surveillance responses. Keep open authority observations separate from actions considered closed internally.
