16.8.4 LD Speeds<br />
Landing speeds are determined by Flaps Setting and AUW<br />
SPEED Definition RMK & Specifications<br />
VREF Reference Landing Speed<br />
Speed at SH in a specific LDG<br />
config (cf. manual)<br />
VREF=1,3.VS VAT Target Threshold Speed Speed at whitch ACFT cross the THR at Screen Height (SH)<br />
V AT0 All # 5% Slope V ATO ≥ 1,3. V S0<br />
V AT1 1 # out VAT1 ≥ V AT0<br />
V MCL<br />
Min. Contr. Speed on the Air (LD config)<br />

16.8.5 Micellaneous Speeds<br />
VIMD Speed of Minimum Drag (cf Drag-Speed curve)<br />
VIMP Speed of Minimum Power (cf Power-Speed curve)<br />
VX Max AoC Speed<br />
VY Max RoC Speed ≈ VX+10kts<br />
Max Tire Speed: VLOF,GS= R*(2π. RPM)/60 RPM=…<br />
16.8.6 Limiting Speeds<br />
VMO<br />
Speed at which it is still possible to decrease Thrust->Idle or<br />
Increase it-> Max TO without encountering dangerous flight<br />

MMO Same as VMO but in Mach. At High Altitide, when climbing at C ste IAS => M⇑…<br />
VNO Normal Operating Speed. Max permitted speed for normal operations..~=V RA<br />
VNE Never Exceed Speed (General Aviation-Jar23).<br />
VLO Max Speed for Lowering Landing Gear.<br />
VLE Max Speed with Landing Gear Lowered (extended) ≈ VLO depend upon design.<br />
VFE Max Flaps Extending Speed.<br />
VRA Max Rough Air Speed.~=V NO<br />
VA Design Manoeuvring Speed (Full Aerodyn Ctl without overstress)<br />
MFS Free Stream Mach Number. Mesurée à un point non affecté par l’onde de pression.<br />
ML Local Mach Number. Idem MFS mais mesurée à un point spécifique.<br />
MCRIT Local Mach Nbr=1… at any point of the ACFT.<br />
MLIM=MCD Critical Drag Mach Number. Liée à l’augmentation de drag dans la zone trans<br />
sonique. MLIM=1…1,5.MCRIT<br />
