AP127 Flight-Training Ecosystem

01The five websites

Plus one experimental optimizer (flight-scheduler) that is local-only and not part of the deployed set.

flight-scheduler — experimental optimizer (not deployed)

02Cloudflare Workers — 3 services

All free-tier, all in account ae38e04e56d0ae52d3ec47ad29977587.

ap127-data-api worker source

export default {
  async fetch(request, env) {
    const allowedOrigin = env.ALLOWED_ORIGIN || '*';
    if (request.method === 'OPTIONS') return new Response(null, { headers: {
      'Access-Control-Allow-Origin': allowedOrigin,
      'Access-Control-Allow-Methods': 'GET', 'Access-Control-Max-Age': '86400' }});
    if (request.method !== 'GET') return new Response('Method not allowed', { status: 405 });
    const data = await env.KV.get('ap127_slice', 'json');
    if (!data) return new Response(JSON.stringify({ error: 'No data' }), { status: 503,
      headers: { 'Content-Type': 'application/json' }});
    return new Response(JSON.stringify(data), { headers: {
      'Content-Type': 'application/json', 'Cache-Control': 'no-store',
      'Access-Control-Allow-Origin': allowedOrigin }});
  },
};

03Data sources & feeds

Operations feed → flight-data.js

A Google Apps Script web-app renders the academy Flight Operations Portal. The schedule lives in a JS object flightCache inside a sandboxed cross-origin iframe — so a headless Playwright browser is needed, not a plain GET.

Progress feed → cache.json

Google Sheets published as per-batch CSV, read through a second Apps Script relay (CORS bridge = the RELAY_URL secret).

const CSV_URLS = {
  AP124: "docs.google.com/spreadsheets/d/e/2PACX-1vRQK_to…/pub?gid=416854743&output=csv",
  AP126: "docs.google.com/spreadsheets/d/e/2PACX-1vQB8PiZ…/pub?gid=416854743&output=csv",
  AP127: "docs.google.com/spreadsheets/d/e/2PACX-1vQNxzCi…/pub?gid=416854743&output=csv",
};
function doGet(e){
  const url = CSV_URLS[(e.parameter.batch||"").toUpperCase()];
  if(!url) return json({error:"Unknown batch"});
  return ContentService.createTextOutput(UrlFetchApp.fetch(url).getContentText("UTF-8"))
           .setMimeType(ContentService.MimeType.TEXT);
}

runScheduler — greedy capacity simulator (not a fetch)

After parsing the CSVs, update-cache.js projects every student's future lessons forward to compute planned[] · finish · monthly.

04Auto-fetching mechanism

End to end, every 5 minutes, driven by the dispatcher worker.

Reliability features

05Telegram notification system — Watchdog

The Telegram system is entirely the ap127-watchdog Cloudflare Worker (repo CMDV2/watchdog/). No Telegram code exists anywhere else in the repos. Every 5 min it fetches AP-127 flights, diffs vs the previous snapshot, and sends one Telegram message per change to the affected student.
