**Document:** RPT-MRTX-FT-001 | **Type:** Test report
**Revision:** v1.0 | **Date:** 3 June 2026
**Prepared by:** Aerix Defense Systems (fictional) — Flight Test Group
**Verifies against:** SRD-MRTX-001 §3.1, §3.2, §8.2

## 1. Test Objectives

Demonstrate endurance (SRD-3.1), cruise airspeed (SRD-3.2), and wind tolerance (SRD-8.2) for the MRT-X air vehicle.

## 2. Test Conditions

| Parameter | Value |
|---|---|
| Site | Coastal test range, sea level |
| Day | Standard day, +15 °C |
| Air vehicle | Tail #2, series-hybrid |
| Fuel load | Full wet-frame |

## 3. Endurance Test

Air vehicle Tail #2 was flown to fuel exhaustion (with reserve) in a loiter profile. 

| Run | Configuration | Endurance achieved |
|---|---|---|
| E-1 | Air vehicle, **no payload installed** | 2 hr 47 min |
| E-2 | Air vehicle, comms relay payload (1.1 lb) | 2 hr 31 min |

Endurance requirement (≥ 2.5 hr) is met. Result satisfies SRD-3.1.

## 4. Airspeed Test

Level cruise sustained at 31 KIAS, exceeding the >25 KIAS requirement. Satisfies SRD-3.2.

## 5. Wind Test

Station-keeping demonstrated in steady winds measured at 24–26 kt with gusts to 30 kt. Hover position held within 3 m. Satisfies SRD-8.2.

## 6. Compliance Summary

Endurance, airspeed, and wind requirements are demonstrated met.

## 7. Revision History

- **v1.0 (3 June 2026):** Initial flight test report. Endurance, airspeed, and wind tolerance demonstrated.

### [INTERNAL — NOT PART OF REPORT] Planted gaps in this document

- **PG-FT-1 (the key one):** SRD-3.1 requires ≥2.5 hr endurance with a **representative mission payload**. Run E-1 (2:47) carried **no payload**. Run E-2 (2:31) carried a **1.1 lb comms relay**, not the **2.0 lb baseline EO/IR ISR payload** (SRD-4.2/4.4) that defines the actual mission. Endurance with the operational ISR payload at 44 lb MGTOW was **never demonstrated**. The "met" claim rests on lighter configurations. A certifier tracing SRD-3.1 to its representative-payload condition should reject this as not-yet-verified. (Category: verification gap — requirement not demonstrated in operational config.)
- **PG-FT-2:** §5 wind test reached 24–26 kt with gusts to 30 kt, but SRD-8.2 specifies 25 KIAS. Steady condition is marginal (24–26 brackets the 25 limit) and the report does not state whether the requirement is steady wind or gust. (Category: AMBIG — marginal/undefined condition.)
- **PG-FT-3 (clean / control):** Airspeed (§4, 31 KIAS vs >25 requirement) is cleanly demonstrated. Engine should NOT flag SRD-3.2.
