FSX Grumman X10F-1 Jaguar Review / Phase 1 Flight Test By PhrogPhlyer This article will document a Phase 1 flight test for the FSX Grumman X10-1F Jaguar. The model was developed by uenoshing and is available on FlightSim.com (download here). His eight years of development are immediately apparent in the high level of photo quality texturing and a detailed and functional VC (3D cockpit). My initial impression when flying was that this is an excellent example of the transitionary aircraft of the jet age. Early jet engines were very low powered compared to newer engines. These aircraft were slow and heavy. And their flight characteristics were similar to the later model propellor driven fighters. If you want to fly at Mach and near Mach speeds, this generation of jets is not for you. The XF-10F is a fun and very visually and functionally detailed aircraft. It belongs in the hangar of anyone who enjoys early jets. The aircraft, being very realistic when initially flow, made me wonder what its full range and capabilities were. This is when I decided to do a full Phase 1 fight test. I will be following a very abbreviated version of the Phase 1 process used for actual aircraft. Some sections have been removed since they either do not apply to this particular aircraft or are not well reproduced in FSX. I referred to Naval Fighters Number Twenty-Six, Grumman Swing-wing XF-10F-1 Jaguar by Ginter Books, and modeled this test program loosely around that actual flight tests. http://www.ginterbooks.com/NAVAL/NF26.htm The specific tasks performed, and observations made, are recorded on test cards, one for each area that is being investigated. PRE-FIGHT / CONTROLS CHECK LOW SPEED TAXI and GROUND HANDLING HIGH SPEED TAXI and GROUND HANDLING INFLIGHT TESTS AIRCRAFT DATA CHECKLISTS Test Flight Location Edwards Air Force Base in California was chosen for the location to perform the test flights for the XF-10. It has been the scene for so many test flight activities through the years, most notably the historic breaking of the sound barrier by Chuck Yeager flying in the Bell X-1 rocket plane. Edwards also offers a unique location, away from population centers, stable clear weather, and distinct visible landmarks along its 125 miles of ranges. These are depicted on the aviation Sectional Chart as Restricted Areas (R-2515, R-2524, and R-2502, and R-2502N. Time to get to work. As with every flight, pre-flight is an essential, and regulatorily required activity to ensure that the aircraft is physically safe to fly. Flight #: 1 -- PRE-FLIGHT / CONTROLS CHECK (1 hour) Objectives Validate Pre-flight Condition Ensure Control Functioning As with real aircraft, preflight is a critical activity to make sure that the aircraft is ready for flight. This is when you can look at areas you cannot while flying and verify that all controls and switches are working correctly. For simulator aircraft, you verify that movable features are functioning. PRE-FLIGHT Cockpit Switches Canopy Full Range Open/Close Pitot Extend/Retract Tailhook Extend/Retract CONTROL FUNCTIONING Ailerons - Free/Correct (Correct refers to ensuring that the control surfaces move in the correct direction they should with movement of the cockpit controls Horizontal Stabilizer - Free/Correct Rudder - Free/Correct Wing Retraction Angle - 13.5° minimum sweep Wing Retraction Angle - 42.5° maximum sweep Landing Flaps and Tail Bumper Spoilers Trim (observe full deflections on cockpit indicators) NOTES Controls smooth, no friction or binding felt, minimal force required Aircraft ready for ground handling and flight Flight #: 2 -- LOW SPEED TAXI and GROUND HANDLING (1 hour) Objectives: Validate Ground Handling and Taxi Characteristics Explore Steering and Braking Characteristics Especially for aircraft you have never flown, low speed taxi and ground handling test give you an initial feel for the responsiveness of the aircraft. It also allows you to determine ramp space needed to maneuver around other aircraft and into parking spots. RAMP BRAKING Release parking brake Increase power to start taxi Full brake Record brake action Strong TURN RADIUS Release parking brake Increase power to start taxi Full differential brake in turn direction Full brake and stop after 180 deg of turn Record nosewheel displacement/radius 11 feet LOW SPEED TAXI Release parking brake Increase power to start taxi ?15 KIAS Taxi per Ground Control directions from ramp to runway via taxiways Make small S-turns along taxiway Stop at approach to runway Record taxi characteristics Stable NOTES Aircraft is slow to accelerate from a full stop. Brakes are firm with no apparent fading with full brake application. Turn radius is tight with no lean into outboard gear shock absorber. Immediate response to rudder inputs (nosewheel) without any oversteering or lagging after rudder application. Flight #: 3 -- HIGH SPEED TAXI and GROUND HANDLING (2 hours) Objectives: Validate Ground Handling and Taxi Characteristics Explore Steering and Braking Characteristics High speed taxi gives the pilot an opportunity to become familiar with the aircraft's handling without actually getting airborne (or with very minor lift offs with immediate landings. Acceleration times and runway length requirements are determined during these tests. Keep in mind that runway length requirements should include the length needed to get to takeoff speed AND what is needed then bring the aircraft to a stop. Many pilots have attempted to take off from a short field without considering the second part, stopping distance, with other than optimal results.
