Operating context

The available TB9 information states that the type may be equipped for day/night IFR when the applicable supplement and installation are present. Flight into known icing is prohibited. This reference does not yet establish that G-SCOP's serial-specific paperwork and present equipment satisfy every condition for IFR dispatch.

The conventional panel is valuable for learning attitude/performance flying, instrument scan and raw-data navigation. Modern equipment should fill actual capability or resilience gaps rather than replace serviceable independent equipment without reason.

Known discrepancies and work in progress

Ref Item Status Required disposition
DEF-001 Fuel quantity gauges reported inoperative Open; potentially grounding for VFR and IFR Enter/confirm the defect, diagnose gauges, senders, wiring and power, calibrate as required, and obtain proper release to service.
DEF-002 Garmin GPSMAP 295 failed Remove/scrap; not to be counted as backup No approved IFR capability is lost. Remove obsolete installation cleanly and update records as required.
WORK-001 Existing 25 kHz COM replacement/upgrade Reported in progress Record final model, 8.33 kHz capability, interfaces and release to service.

Baseline evidence to establish

  1. Confirm the AFM/POH and applicable supplements permit the intended day/night IFR operations.
  2. Reconcile the physical panel with the equipment list, modification records and weight-and-balance schedule.
  3. Verify pitot heat, static system, altimeter, ASI and VSI condition and test status.
  4. Verify attitude, turn/slip and stabilised-heading instruments, including gyro power or failure warning.
  5. Confirm OAT, accurate time display, low-voltage/charging indication and practical electrical endurance.
  6. Identify every NAV indicator, glideslope channel, source selector, flag and annunciator.
  7. Test COM, NAV, DME, ADF, transponder and antenna systems in their installed configuration.

Useful model-level figures

The available TB9 pilot-information manual includes the following points. They remain subject to serial, revision and configuration applicability:

  • Total fuel 41.7 US gal, stated usable fuel 40.2 US gal.
  • A demonstrated crosswind of 25 kt; the handbook definition says this certification demonstration is not itself a limit.
  • Landing distance increases quoted for surface and wind conditions, including 7% hard sod, 10% short grass and 25% high grass.
  • A flapless landing calls for an 80 KIAS approach and approximately 60% greater landing distance.
  • The IFR/ILS supplement contains TB9-specific power and speed guidance and warns of possible KING localiser indication interference around certain engine speeds/frequencies.

These are reference prompts, not a substitute for checking the approved handbook pages carried for G-SCOP before flight.

Working principles

  • Repair and document the airworthy baseline before optional avionics work.
  • Understand the installed source, display, power supply and failure mode before replacing equipment.
  • Preserve useful independence between conventional radio navigation and GNSS.
  • Keep certified aircraft functions separate from portable situational-awareness functions.
  • Obtain an installed price and approval path, not merely a box price.
